RBI Treasury Bills (T-Bills) are considered a good investment primarily because they offer an exceptional combination of safety, high liquidity, and predictable, short-term returns, making them ideal for risk-averse investors and for managing short-term financial needs.

Treasury Bills (T-bills) are short-term money market instruments issued by the Government of India through the Reserve Bank of India (RBI) to meet the government’s short-term funding requirements. Considered one of the safest investment options in the financial market, T-bills are backed by a sovereign guarantee and offer high liquidity with predictable returns. These instruments are issued at a discount to their face value and redeemed at full face value upon maturity. The difference between the issue price and the redemption value represents the investor’s return.

This article explains the meaning of treasury bills, their types, features, benefits, limitations, and working mechanism.

Treasury Bills Meaning

Treasury bills are short-term debt instruments issued by the RBI on behalf of the Government of India in the form of promissory notes. They do not carry any coupon or interest payments and are therefore classified as zero-coupon securities.

The primary objective of issuing treasury bills is to meet the short-term financial requirements of the central government. For investors, T-bills are among the safest investment avenues, offering the highest level of liquidity among government securities.

Types of Treasury Bills in India. Treasury bills in India are issued in four fixed tenures:

1. 14-day Treasury Bills
2. 91-day Treasury Bills
3. 182-day Treasury Bills
4. 364-day Treasury Bills

While the tenure of each category remains fixed, the issue price and yield fluctuate depending on factors such as total bids received, prevailing interest rates, RBI’s monetary policy stance, and the government’s funding needs.

Features of Treasury Bills:

1. Zero-Coupon Instruments

Treasury bills do not offer periodic interest payments. Instead, investors earn returns through capital appreciation—the difference between the discounted purchase price and the face value received at maturity.

2. Short-Term Tenure

With maturities ranging from 14 days to 364 days, T-bills are ideal for investors seeking short-term parking of funds with high liquidity and minimal risk.

3. Low-Risk Investment

Backed by the Government of India, treasury bills carry virtually no credit risk. They are considered safer than fixed deposits and often provide better post-tax efficiency for similar tenures.

4. High Liquidity

T-bills can be easily sold in the secondary market before maturity, making them highly liquid instruments.

Who Issues Treasury Bills? In India, treasury bills are issued by the Reserve Bank of India, which has been conducting T-bill issuances since 1917. These bills are issued through periodic auctions held on RBI’s electronic platform known as E-Kuber. Participants in these auctions include banks, primary dealers, financial institutions, mutual funds, trusts, and individual investors.

Banks also use treasury bills to: 1. Raise funds through repo transactions with RBI 2. Fulfil their Statutory Liquidity Ratio (SLR) requirements 3. Minimum Investment in Treasury Bills 4. The minimum investment amount for treasury bills is ₹10,000, and additional investments must be made in multiples of ₹10,000. Upon maturity, the maturity value is automatically credited to the investor’s linked bank account.

Conclusion

Treasury bills are an excellent investment option for conservative investors seeking safety, liquidity, and predictable short-term returns. With sovereign backing, flexible tenures, and ease of access, T-bills play a crucial role in both government financing and investors’ short-term financial planning.

The combination of a product and a service is a product-service hybrid. For example, the iPod and iTunes were a famous example of this approach. Yet, they were complementary hybrids – it was possible to use an iPod without iTunes and vice-versa.

Goods are the material items that the customers are ready to purchase for a price. Services are the amenities, benefits or facilities provided by the other persons. Goods are tangible items i.e. they can be seen or touched whereas services are intangible items.

The Service Quality Model or SERVQUAL Model was developed and applied by the American marketing gurus Valarie Zeithami, A. Parshuraman and Leonard Berry in 1988. It is a method to capture and measure the service quality experienced by customers. They developed it to provide a structured way for businesses to assess and understand potential problems in service quality. The core idea of the model was built on the concept that service quality is a function of the gap between what a customer expects and what they perceive to be delivered.  The model was conducted across four different service industries: Banking, Credit Cards, Repairs and Maintenance and Telecommunications.

The reliability depends on to what extent the service is accurate and honest. Responsiveness is about promptly and adequately responding to customer questions or complaints. Competence relates to the expertise an organization has, and the access determines if a customer can quickly and efficiently contact the right department.

The first studies according to the SERVQUAL Model, were carried out exclusively for the services of a telecommunications, a banking and a maintenance company. The previously mentioned researched surveyed consumers and their perceptions of the experienced service quality of these three organisations. The model was later refined to the five dimensions commonly known by the acronym RATER (Reliability, Assurance, Tangibles, Empathy, and Responsiveness). The application of SERVQUAL to electronic commerce and online services (e-service quality) occurred much later, with researchers developing adapted scales like E-S-QUAL in the 2000s to address the specific characteristics of the electronic service environment. To clarify the model I am giving hereby Indigo Airlines example.

Five Dimensions of SERVQUAL Model:

Reliability

The ability to perform the promised service dependably and accurately. Indigo Airlines’ reliability is a mixed bag, with opinions divided on its punctuality and service quality. The airline’s focus on punctuality is a key operational attribute, which, while a process, provides a consistently reliable, almost “tangible”, result for customers in the form of on-time arrival. IndiGo has a reputation for a solid safety record with well-trained pilots.  While recent reports suggest a decline, some travellers have experienced on-time flights. IndiGo also claims a strong record in this area. The airlines have maintained its operational efficiency. Their domestic check-in and boarding are efficient. It’s a no-frills, low-cost airline.

Assurance

The knowledge, courtesy, and competence of employees that instil trust and confidence. Indigo Airlines’ assurance includes optional add-on services like Domestic TravIensure insurance for medical emergencies and trip cancellation and Delayed and Lost Baggage Protection for compensation if checked-in bags are delayed or lost. However, “assurance” can also refer to the airline’s overall commitment, which, according to some consumer reports, has led to recent legal action due to service deficiencies and broken promises, particularly concerning flight cancellations and compensation. Assurance in aviation services is a continuous process of monitoring, evaluating, and verifying that safety and quality standards are met across all operations, including flight operations, maintenance, and ground services. It involves activities like audits, data analysis, and corrective actions to ensure that safety management systems are effective and that the organization complies with regulatory and internal requirements. The goal is to ensure consistent safety and quality to protect passengers, maintain customer trust, and drive continuous improvement.

Tangibles

The physical appearance of facilities, equipment, and personnel. Tangibles are the physical elements of a service, providing visible cues about its quality. IndiGo Airlines, like any service-based company, uses tangibility to provide physical evidence of its service quality and brand promises. This helps customers evaluate the intangible service they are purchasing (air travel).  Key tangible elements of IndiGo’s service include modern and well-maintained fleet. IndiGo is known for operating a single, modern fleet type (primarily Airbus A320s and A321s, with A350s on order). The physical aircraft, their clean interiors, and consistent appearance provide a strong tangible cue of reliability and professionalism. Appearance: Staff wear neat and professional uniforms, which contributes positively to customer perception of the airline’s tangibility and service quality. Every physical touchpoint is consistently branded, from the airport counters and boarding passes to in-flight materials like seat headrests and air sickness bags. This consistency reinforces the brand image and promise. The user-friendly website, mobile app, and self-check-in kiosks are considered tangible aspects of the service, providing a seamless and efficient experience. On ground facilities include clearly identifiable check-in counters, baggage handling systems, and other airport facilities that help manage the physical process of travel.

The airline’s focus on punctuality is a key operational attribute, which, while a process, provides a consistently reliable, almost “tangible”, result for customers in the form of on-time arrival.

Empathy

The degree of caring, individualized attention provided to customers. Indigo Airlines’ reputation for empathy is mixed, with recent viral stories highlighting positive customer interactions, particularly with differently abled staff members, while other passengers report negative experiences of inflexibility and lack of compassion in difficult situations. While some customers and observers have praised the airline for employee empathy, a 2024 study also found empathy to be a contributing factor to their service quality, suggesting a perception of empathy is present, even if inconsistent. A passenger shared a heartwarming experience with a hearing and speech-impaired staff member who provided an exceptionally smooth check-in and went above and beyond with extra perks, leading to praise for the airline’s “true inclusion in action”.

Responsiveness

The willingness to help customers and provide prompt service. IndiGo Airlines’ responsiveness is a mixed picture, as it is known for its strong on-time performance but receives criticism for its customer service responsiveness in areas like communication and handling complaints. While the airline emphasizes its commitment to punctuality and customer satisfaction, some studies have highlighted gaps between customer expectations and the airline’s responsiveness, particularly regarding keeping passengers informed and resolving demands promptly.

How is the model used?

Questionnaire

A survey is used to ask customers about their expectations and perceptions of a service.

Gap analysis

The difference between the perception score and the expectation score for each dimension is calculated. A negative gap indicates that the perceived service is worse than expected, while a positive gap indicates it is better. Actionable insights are studied by analysing the gaps across the five dimensions, businesses can pinpoint specific areas that need improvement, such as investing in customer service training (to improve empathy) or updating physical facilities (to improve tangibles). The gaps are based on following parameters:

Knowledge gap

A gap arises when an organisation’s knowledge of customer expectations is lacking, preventing them from approaching consumers in the right way.

Standards gap

The organisation has already formed its own idea about what the customer expects from their service. If this idea is wrong from the start and does not correspond to what customers expect, there is a significant risk that the organisation will translate it wrongly into a quality policy and corresponding rules.

Delivery gap

A gap can also occur when the organisation offers service that is different from what the consumer had expected. This also involves an incorrect implementation. For instance, in the way employees carry out policy.

Communications gap

Sometimes, the external (marketing) communication that the organisation sends out, can create the wrong expectations among customers. It also happens that the organisation communicates and promises things that are not in line with what they can deliver.

Satisfaction gap

Dissatisfaction results from a (significant) difference between the service a customer expects and the service they experience. Eventually, this will lead to the biggest gap in the experience of quality.

Olfactory Marketing (or Olfactory Branding) is the strategic use of fragrance to define and enhance the identity of a space such as a hotel, home, restaurant, banquet hall, theatre, clinic, or retail store. It is an immersive and multisensory marketing approach, where brands create deeper connections with consumers by engaging the five human senses—sight, sound, smell, touch, and taste. Among these, smell is the most direct pathway to the human psyche, as it is closely linked to memory and emotion.

A carefully designed fragrance can bypass rational thinking and act as a powerful emotional language, instantly triggering feelings, associations, and memories. Because of this unique ability, olfactory cues can strongly influence perception, mood, and behaviour. Olfactory branding harnesses the emotional weight of scent to communicate a brand’s personality and values, making the brand identity more memorable, enchanting, credible, and persuasive. When used effectively, it transforms ordinary spaces into distinctive experiences that customers subconsciously recognize and trust.

The aroma of freshly baked cookies is a classic example of scent marketing in a bakery or restaurant, while floral fragrances are commonly used in women-oriented service environments such as salons, spas, and clothing stores. Hotels strategically diffuse different aromas in various areas to create a sense of luxury and relaxation, improve guests’ comfort, and motivate them to return. New cars are also associated with a distinctive “brand-new” smell. Dealerships and manufacturers use artificial, long-lasting fragrances so that buyers can experience this sensation when purchasing a vehicle. The brand Rolls-Royce owes part of its success to the introduction of a signature fragrance in the Silver Cloud model in 1965, which is still sprayed under the seats today to recreate the original aroma and convey a sense of luxury to drivers. Similarly, in-store aromas at Café Coffee Day and the world’s first registered smell trademark for rose-scented tyres demonstrate how scent is used as a branding tool. These methods aim to evoke nostalgia, enhance premium experiences, and create immediate, Pavlovian emotional responses to products.

While visual merchandising primarily appeals to the sense of sight through elements such as colour, lighting, and spatial layout, integrating scent (olfactory merchandising) significantly enhances the retail atmosphere, influences consumer behaviour, and strengthens brand identity. Scent directly interacts with the limbic system; the part of the brain responsible for emotions and memory making it a powerful subconscious driver of shopper responses.

Increased dwell time

Pleasant, mild, and relaxing fragrances such as lavender, vanilla, or citrus encourage customers to remain in the store longer. A well-calibrated aroma can elevate mood and shopping enjoyment, with several studies suggesting that scent marketing can increase impulse buying by up to 40%.

Reduced anxiety

Calming scents help create a comfortable shopping environment, lowering stress levels and motivating customers to explore the store more freely. Perhaps one of the best examples of marketing scents whether the mark is Starbucks, which aromatizes its cafes with the aroma of freshly brewed coffee to the people passing outside what they perceive and feel the urge to go for a coffee and to live the experience of the brand.

Choosing the right business aroma requires aligning scent with brand identity

It’s for target audience, and desired emotional response to create a memorable customer experience. Key steps include defining the intended mood. The business must determine how they want customers to feel e.g., relaxed, energized, luxurious, or nostalgic. This scent becomes a non-verbal communicator, a sensory logo that evokes emotion, communicates quality, and strengthens brand loyalty. For example: A wellness brand might lean into herbal, spa-like aromas to promote tranquillity. A luxury retailer might use warm, musky notes that evoke exclusivity and sophistication.

Five-star hotel brands use olfactory marketing to create a lasting, emotional, and memorable brand identity, often boosting guest loyalty and enabling higher perceived value. They deploy custom, branded scents through HVAC (heating, ventilator and air-conditioning) systems in lobbies, spas, and corridors, designed to evoke specific emotions such as relaxation or energy and enhance the overall sensory experience. Hotels curate unique fragrances that align with their brand identity (e.g., modern, luxurious, or tranquil). Examples include: Taj, Westin, Sheraton, Leela,  they use a white tea and cedar scent for a refreshing, calming, and consistent brand experience globally. Westin uses “Bliss,” a citrusy, energetic, and modern scent to match their, high-energy, boutique, “always-on” brand. Sheraton uses bergamot, jasmine, and freesia to foster a calm and relaxing environment. Bulgari Hotels & Resorts uses a specialized green tea fragrance for a healing, luxurious atmosphere.

Restrooms maintain with consistent, high-quality, and often, automated scent systems to maintain a high-end feel throughout the property. Consistent Brand Experience: Brands use technology to ensure a uniform scent experience across all locations, reinforcing, and extending, the brand, and encouraging, return, visits. A luxury brand might use rose or jasmine , while a youthful brand might prefer fruity scents.

Conclusion

Olfactory marketing, or scent marketing, has indeed become a common and highly effective strategy across various industries to boost brand recognition, enhance customer experience, and drive sales. It’s become a strategic tool in modern movie theatres, flights, trains to enhance the audience experience, and create memorable brand associations. While popcorn scent is the most classic example, theatres now use advanced technology for broader, more immersive scent strategies. By leveraging the fact that the sense of smell is closely linked to the brain’s limbic system which manages emotion and memory. Brands use tailored fragrances to create lasting impressions.

In the modern world, particularly in large cities, a growing lack of trust and heightened awareness of potential threats such as scams and violence have made people more withdrawn and less willing to engage with strangers. Despite these challenges, several initiatives and tools have emerged to foster human connection and rebuild social trust. One such initiative that stands out is an experiential marketing campaign by Nescafé in Germany. In 2015, Nescafé installed temporary coffee vending machines in Berlin that encouraged interaction among strangers. These machines were not permanent fixtures across German roads but were part of a short-term campaign designed to promote social connection through shared experiences.

Nescafé, the world’s most popular coffee brand owned by Nestlé, has a legacy dating back to 1938. In 2015, Nestlé launched REDvolution, a global marketing campaign aimed at rejuvenating the Nescafé brand. The initiative sought to unify global branding, modernize the brand’s image to appeal to younger consumers, and strengthen its competitiveness against fresh coffee chains such as Starbucks. Central to the campaign was the introduction of new products and formats, including Dolce Gusto coffee machines, alongside the adoption of the slogan “It all starts with a Nescafé.” REDvolution standardized Nescafé’s visual identity worldwide, increased its focus on digital and social media engagement, and positioned the brand as contemporary and socially relevant. Through innovation and consistent branding, the campaign aimed to ensure that Nescafé’s instant coffee remained relevant within an evolving global coffee culture.

Nescafé installed two coffee vending machines at opposite sides of a busy pedestrian crossing. Each machine had a button with the message “Push Together”. To receive a free cup of coffee, two strangers one on each side of the street had to press the button simultaneously. When they succeeded:

• Both machines dispensed a free coffee
• A video screen activated, allowing the two participants to see, smile, wave, and interact with each other in real time
• The moment transformed an ordinary street crossing into a shared social experience

The marketing objectives were to humanize the brand by associating it with warmth and connection. Reinforce Nescafé’s brand promise: coffee starts conversations, create emotional engagement, not just product awareness, generate shareable content for social media and PR coverage.

The campaign was built around the insight that modern urban life discourages spontaneous human interaction, even though people crave connection. Nescafé positioned itself as the catalyst that brings people together even strangers.

The goal of the act was to encourage spontaneous social interactions among strangers in a city that Nescafé’s research suggested was one of the world’s “loneliest”. The campaign was successful in its intent, reportedly leading to numerous waves, smiles, high fives, and conversations, but the special machines were specific to this temporary campaign and not a common feature of German roads.

Nescafé’s Instant Connections campaign, that shows strangers in Berlin how they can connect over a cup of coffee, has received over a million views on Facebook and more than 85,000 on YouTube. Hidden cameras filmed commuters on either side of a busy road, each pressing what looked like a regular pedestrian crossing button – except that the buttons were labelled ‘push together’.

When two people figured out they had to press the button at the same time, they were both rewarded with a cup of Nescafé that was delivered automatically by vending machines camouflaged beneath the pedestrian crossing button. In one day, the campaign has helped over 600 people connect over Nescafé coffee.

“We are delighted to have triggered so many spontaneous social interactions that otherwise would not have happened. A great cup of Nescafé is a natural way to start real connections, and we wanted to bring this to life in an unexpected, innovative, and enjoyable way,” said Michael Chrisment, Global Head of Integrated Marketing for Nescafé.

This approach clearly reflects Nescafé’s reinvigorated REDvolution strategy, which aims to unify product innovation and brand communication across more than 180 global markets. By emphasizing human connection, shared experiences, and contemporary consumer engagement, the campaign demonstrates how Nescafé translates its global brand promise “It all starts with a Nescafé” into meaningful, real-world interactions.

The collegial model in organizational behaviour (OB) is a framework built on partnership and teamwork, where managers and employees collaborate as colleagues, fostering mutual respect and shared responsibility. Collegial is an adjective describing a work environment where responsibility and authority is shared equally by colleagues. This model encourages a sense of partnership, with managers acting as joint contributors and employees feeling a sense of fulfilment and responsibility, leading to self-discipline and moderate enthusiasm for high-quality work. Managers are called joint contributors because their role involves a blend of individual contributions (their own specific tasks, plans, and expertise) and the collective contribution of the teams they lead. They facilitate the work of others while also making individual, specialized contributions to the organization is an extension of the supportive model and works effectively in dynamic environments like a creative team. 

Samsung has an organizational culture that emphasizes innovation through empowering employees and fostering teamwork. This collegial model utilizes flat hierarchies, shared decision-making, and cross-functional teams to promote collaboration and innovation. The collegial model in organizational behaviour focuses on promoting teamwork and a sense of shared responsibility among colleagues. Samsung incorporates several elements of this model into its operations. Samsung utilizes flatter organizational structures to encourage open communication and reduce status-based conflicts. Managers are encouraged to act as coaches or team members, promoting team performance and ensuring a positive, motivating work environment rather than a strictly hierarchical one.

Collegial models work the best in educational Institutions. Schools and colleges, particularly at the primary level or within specific departments like university faculties like faculty of science, faculty of commerce, management, law etc. They often adopt a collegial approach for policy and curriculum decisions.

Similarly in the non-profit organizations (NGOs) like Goonj, Nanhi Kali, CRY, and the Akshaya Patra Foundation, which rely on volunteerism and shared humanitarian goals, inherently leverage the self-actualization and teamwork principles of the collegial model to drive their initiatives. The most famous examples of universities that primarily use the collegial model of governance are the UK’s ancient institutions, the University of Oxford and the University of Cambridge.

Some of key principles of the collegial model are as follows:

Partnership:

The foundation is a partnership between employees and management, where everyone is a “colleague” working towards common goals. In the collegial model, partnership is the foundation where managers and employees work together as colleagues with a shared purpose. This approach emphasizes teamwork and mutual contribution, fostering a collaborative environment where responsibility and decision-making are shared, leading to greater employee motivation and commitment.

Teamwork:

A team-based approach is emphasized, with a focus on collaboration and shared responsibility. This model emphasizes collaboration, shared decision-making, and self-discipline over traditional hierarchical structures, motivating employees by meeting their psychological needs for self-actualization and contribution.

Mutual respect:

The model promotes a culture of mutual respect between managers and employees, breaking down traditional hierarchical barriers. Mutual respect is not merely an optional courtesy but a core, driving force for motivation and a strong, positive organizational culture. Without it, the model struggles to function effectively, as trust and open communication are essential for its success.

Managerial role:

Managers are seen as joint contributors and facilitators, focusing on guiding employees and promoting a sense of participation and cooperation.

Employee orientation:

Employees are oriented toward responsible behaviour and self-discipline, driven by an internal obligation to produce high-quality work.

Psychological result:

Employees experience a sense of fulfilment and self-actualization, which leads to moderate enthusiasm and commitment to the organization’s success. Psychology in organizational behaviour is the application of psychological principles to understand and improve the workplace. It studies how individual, group, and structural factors influence behaviour within organizations, focusing on areas like employee motivation, job satisfaction, productivity, and well-being.

Examples of organization using collegial model:

The Murugappa Group is a Chennai-based Indian conglomerate with diverse businesses in engineering, agriculture, financial services, and manufacturing. Founded in 1900, the group is one of India’s oldest business legacies and is managed by the Murugappa family, with prominent companies including Carborundum Universal, Cholamandalam Investment and Finance, Coromandel International, and Tube Investments of India. Its business interests span a wide range, from abrasives and auto components to bicycles, fertilizers, sugar, and tea.  It is a family-promoted conglomerate with over 125 years of history; the Murugappa Group has grown from a banking and money lending business to a diversified industrial powerhouse. Murugappa group uses the collegial OB model.

Dabur India Ltd operates with a work environment and talent management practices that are described as fostering a culture of collegiality. This approach emphasizes teamwork, mutual trust, and a cohesive work environment rather than strictly following a formal, top-down “collegial model” as a rigid organizational structure. Dabur India Ltd. is a leading Indian multinational consumer goods company, founded in 1884, that specializes in Ayurvedic and natural healthcare products. Headquartered in Ghaziabad, it is one of the world’s largest Ayurvedic and natural healthcare companies and has a vast portfolio of over 250 products across hair care, oral care, health care, and foods. Dabur has a global presence in over 120 countries and is known for its flagship brands like Dabur, Vatika, Hajmola, and Real.  

PERT – Program Evaluation and Review Technique and CPM (Critical Path Method) are project management tools for scheduling and controlling projects by breaking them into smaller tasks and analysing their dependencies. PERT is used for projects which usually are run with uncertain activity durations. PERT charts are used using a probabilistic model with optimistic, most likely, and doubtful time estimates. CPM is used for projects with known, deterministic durations, focusing on time-cost by balancing  trade-offs to find the critical path. 

Kingfisher Airlines didn’t give importance to PERT charts. The airline’s eventual collapse was ascribed to a lack of proper PERT procedure in terms of delegation, scheduling of flights, food arrangements and other services in flights. Aircraft maintenance, pilot and aircraft staff duties, scheduling of their work, misbehaviour of staff, and a lack of attention from the owner, highlighting fundamental failures in project management that no planning technique could overcome without proper execution and governance.

A study of ten failed PPP highway cases in India cited issues such as unreasonable traffic and revenue estimates, inflexible contracts, unbalanced risk allocation, regulatory hold-ups, and limited oversight. These systemic flaws in planning and risk management directly relate to the potential pitfalls of relying too heavily on initial PERT estimates without continuous monitoring and adjustment. PERT requires regular monitoring. The projects include the Delhi-Mumbai Expressway, Nagpur Metro Rail, Navi Mumbai International Airport, GIFT City, and the development of Multi-Modal Logistics Hubs in Greater Noida. Other examples include the Operation, Management and Development (OMD) of Multimodal Terminal (MMT) at Varanasi, the development of the Indian Institute of Management (IIM) – Udaipur infrastructure, the Redevelopment of Gwalior and Amritsar Railway Stations, and the construction of Eco-Tourism Resorts in the Andaman and Nicobar Islands and Lakshadweep.

PERT requires detailed purpose. Projects with uncertain timeframes, such as research and development, by focusing on minimizing project completion time are dangerous. PERT timeline uses a probabilistic approach with three time estimates for each activity: optimistic, most likely, and pessimistic.  It is concerned primarily with time and risk assessment, allowing for contingency planning.  It is best for projects with a high degree of uncertainty and a non-linear or unpredictable flow of activities.

The Critical Path Method (CPM) is crucial in project management because it helps identify the longest sequence of dependent tasks to determine the minimum project completion time. This allows project managers to effectively prioritize tasks, allocate resources, track progress, and proactively mitigate risks to ensure timely project delivery. By highlighting critical tasks that cannot be delayed, CPM provides a clear roadmap and facilitates better communication, helping to avoid bottlenecks and schedule delays.

The Bullet Train Project (Mumbai-Ahmedabad High-Speed Rail project has been analysed using both CPM and PERT in research papers to examine critical activities, interdependencies, and estimated timelines, demonstrating the application of these tools in large-scale, high-value infrastructure planning. For construction of rail tracks, the general application of CPM and PERT in the construction of railway lines has been studied, showcasing how these techniques help optimize schedules, manage costs, and ensure timely completion of complex track-laying activities.

The purpose of CPM is to manage projects with predictable activity durations and focuses on balancing time and cost. It uses a deterministic approach with a single, fixed time estimate for each activity. CPM focuses and identifies the critical path—the longest sequence of tasks to ensure timely project completion and explores time-cost trade-offs. It is best for projects with well-defined tasks and durations, such as construction and manufacturing.

While working on large infrastructure and construction projects publicly detailed PERT charts are less common in general descriptions, the nature of India’s major infrastructure drives, such as the Bharatmala Pariyojana (a massive national highways program), the Mumbai Trans Harbour Link, and various other large-scale building and engineering projects, necessitates the use of robust project management methodologies like PERT/CPM for effective planning and execution. Software tools like Primavera P6 (commonly used for engineering and construction) are leveraged for such high-budget projects, which inherently integrate PERT-like functionalities for risk and uncertainty visualization.

Conclusion

Both tools of project management PERT and CPM are often used together because they are complementary. They both involve creating a project network diagram to visualize tasks and dependencies. They help project managers break down large projects, determine the critical path, make decisions, coordinate teams, and analyse if the project will be completed within budget.

In the corporate world bandwidth refers to the capacity of an employee to complete a task in give time frame with accuracy. An organization expects their employees to complete a task with available resources, handle tasks alertly, handle projects with finesse, maintain transparency and proper flow of information within a business context. It can refer to the physical capacity of a network to communicate the flow of data related to workload and the ability to address a complex situation. To me, a high-bandwidth person is one who can rapidly intake information, synthesize it, and communicate efficiently. To explain bandwidth in HR I have given example of Mr. Punit Chatwal a renowned Hospitality Industry champion.

Puneet Chatwal of Indian Hotels Company Ltd MD & CEO has large bandwidth of multitasking and ambition to grow IHCL since 2017, the company got on board a very aggressive target of 50 percent growth in the number of hotels. Since then, they have added 70 new hotels to their portfolio. Primarily, this has been driven through strategy, focus, a change in business model, and a culture of rewarding performance. As the company has grown, they have been strengthening the culture of the company. Chatwal is  disciplined and a visionary.

Networking is vital for professional and personal development because it raises connections, facilitates knowledge sharing, and creates opportunities for growth. It expands a person’s   reach for opportunities, provides valuable advice and support, and enhances his  professional reputation. Human bandwidth refers to the amount of mental and emotional capacity a person has available to process information, make decisions, and handle various tasks and challenges at any given time. It’s a limited resource, like time or physical energy, and when it’s depleted, individuals may have trouble focusing, making decisions, or managing stress. Puneet Chhatwal is a people’s man; he is frequently described as a leader who values people and is focused on building strong relationships within his organization and in the hospitality industry.  

Bandwidth is often used as a metaphor for the available time, energy, and resources to take on new responsibilities. When someone says, “I don’t have the bandwidth,” they often mean they don’t have the capacity and energy to handle additional work. This can relate to the number of ongoing projects, workload, or the complexity of tasks.

As leaders, manager, it is very important to know that everyone has a different capacity. For example, if it takes one person to complete a certain task in one hour, it can take the other 3-4 hours. Managers must assign the work to each team member according to what they can handle.

Bandwidth in HRM signifies an employee’s ability to manage a workload, process information, and make decisions within a specific timeframe. It includes mental energy, emotional stability, and time that an employee can allocate to work. Bandwidth affects an employee’s ability to prioritize tasks, meet deadlines, and handle the complexities of their role. When an employee’s bandwidth is stretched thin (e.g., due to excessive workload, high stress, or lack of support), it can lead to burnout, decreased productivity, and reduced decision-making quality. 

Puneet Chatwal says that his people are fundamental to the desirable brand equity enjoyed by IHCL. He involved 40 of our senior leaders in creating the ambitious 5-year business strategy. This was supported by ‘culture meets’ that helped in fostering an environment of collaboration and teamwork. It has helped people to take accountability and become highly engaged and invested in the company’s success. Chatwal is known for understanding people he is future proofing the talent to ensure they are ready for the growth that is coming from within the industry and IHCL’s aggressive pipeline. He believes in Leadership Pipeline Model of HR. The model does not need to hire stars from outside for the key positions. Outsiders clog the pipeline because of the culture they bring does not go well the organizational culture. 

Conclusion: Bandwidth is not will power, a person can’t just think harder to get more.  Bandwidth is not intelligence or knowledge you can’t educate yourself into more. Bandwidth is not time; we can’t control it so easily. Bandwidth is more like the physiological limit of how much “thinking” we can do in one moment.  When bandwidth demands are high, but bandwidth availability is low, what happens then?  Usually it means we are weaker, we are experiencing a burnout, we are fagged out and we will fall short of the expected quality of work.

The Bottom of the Pyramid (BOP) refers to the poorest two-thirds of the global population which is over 4 billion people living on less than $2 or $5 a day. Popularized by C.K. Prahalad in 2004, it represents an untapped, high-volume market. Businesses target this segment with affordable, high-volume, low-margin products (e.g., small shampoo sachets) to ease poverty while generating profit.  Roughly two-thirds of the population, or about 68%, live on less than $5 per day. The global Bottom of the Pyramid (BoP) consists of approximately 4 billion people living in poverty, typically defined as those with incomes below $2.50 to $3.00 per day. This segment represents the largest, yet poorest, socio-economic group, often characterized as a major market opportunity. Roughly 4 billion people, representing the bottom two-thirds of the economic pyramid. This segment is characterized by subsistence-level income, high levels of informality in labor, and low literacy rates. It’s the lowest income tier (tier 3 and 4) of the global economic pyramid.

Market Opportunity

The collective purchasing power of the poor is immense, its voluminous creating a “fortune” for companies that can design sustainable, scalable business models, such as small-packet shampoos, low-cost banking, or affordable health services. The market size is roughly 4 billion people, primarily in Asia, Africa, and South America. The BoP is highly price-sensitive, often with irregular income streams.

While offering immense growth potential as a battleground for corporate revenue, BoP markets present challenges like poor infrastructure, which makes distribution costly.

Micro-distribution

Using local, community-based networks (e.g., selling through local women in rural areas) eg. Project Shakti of HUL. Even a kiosk (tapari)  business is a high-traffic, low-overhead retail model located in busy streets, offering products or services through small, often self-service booths. It offers a cost-effective entry for entrepreneurs, with opportunities in food, retail, or tech, often allowing for flexible, mobile, or fixed setups. Key success factors include prime location, eye-catching design, and efficient inventory. Allowing consumers with daily income to purchase products they cannot afford in large, upfront quantities in sachets.

Kiosks allow utilizing technology to offer services like telecom or solar power in small, manageable increments. They act as local solutions leveraging local knowledge and resources to create sustainable local enterprise networks.

FMCG products are the top-selling category

FMCG products are often sold in micro-packaging to reduce upfront costs for low-income consumers. Sachets, or single-use, small-unit packaging, are a foundation of marketing to the Bottom of the Pyramid (BoP)the largest but poorest socio-economic group. These products are designed for consumers with limited daily cash flow, allowing them to purchase branded goods in small quantities at affordable prices. Personal care products such as shampoos, soaps (e.g., Lifebuoy), toothpastes (e.g., Colgate), hair oils, and fairness creams. Detergents and cleaning soaps powder detergents (e.g., Nirma) and dishwashing soaps. And, edible items such as cooking oils, tea, spices, and sugar. To make the product accessible to BoP, Maggi introduced smaller packs at low, affordable price points, such as ₹5 (Chotu Maggi) and ₹10, allowing for impulse purchases. Companies such as Hindustan Unilever (HUL), Procter & Gamble (P&G), CavinKare, Dabur, Britannia, and Nestle use this approach to penetrate rural markets and, increasingly, to combat the rising cost of living in urban areas. Examples include small pouches for detergent (Surf Excel), shampoo sachets (Sunsilk), and small biscuits/snack packs (Good Day).

In many developing markets, small neighbourhood stores (“sari-sari” stores in the Philippines, kirana stores in India) are the primary source of goods, which perfectly suits the distribution of single-use sachets.

Functional and affordable technology

BoP consumers are eager to adopt technologies that improve their quality of life or productivity. Low-Cost mobile handsets: Budget-friendly, feature-packed mobile phones, especially from brands like Micromax, Spice, and Nokia. Solar-Powered lights and devices like D. Light provide essential, sustainable, and portable lighting and phone charging capabilities. Low-Cost household appliances low-energy products like the “ChotuKool” refrigerator. Chotukool is an innovative approach to tackling the problem of food storage in India, a country in which around one-third of all food spoils and an estimated 80 percent of households do not have access to or use a refrigerator. Chotukool is the brainchild of Gopalan Sunderraman, Executive Vice President of Godrej & Boyce Manufacturing.

Success at the BoP often requires reinventing the business model, not just the product. The model emphasizes that innovations should be co-created with the BoP consumers, shifting from “selling to the poor” to “working with the poor”.  For example, Tata Nano, Tata Ace is re-engineering automobiles for affordability. Aravind Eye Care System is  High-volume, low-cost eye surgeries. The strategy has made the eye-care hospital stand out as an ethical when it provides products that improve quality of life, such as basic health, hygiene, or connectivity solutions.

Bottom of Pyramid Business Model is Huge

Consisting of over 4 billion people, this market is not small; it constitutes most of the global population. BoP consumers are highly price-sensitive, yet value-conscious. They often require specialized products (e.g., smaller packaging) and yet are value-conscious. They exist in rural and informal urban economies. The market is estimated at around trillion annually, grows faster than the global GDP. It is considered a source of innovation, offering opportunities for companies to create shared value. Most of this population is concentrated in developing nations, with significant populations in China, India, Brazil, and Indonesia. Consumption at the BoP is often described as “frugal in size but voluminous in total,” meaning products are sold in small quantities like sachets to a vast number of people, leading to high total sales revenue. The population at the bottom of the pyramid is projected to swell to more than 6 billion people over the next 40 years as global population growth remains concentrated in this segment.

Conclusion

The “fortune” at the bottom of the pyramid, popularised by C.K. Prahalad, suggests that businesses can simultaneously drive profits and lessen poverty by treating this segment as consumers rather than merely as victims of poverty.

Studying international business theories is essential to steer, strategize, and succeed in a globalized economy, enabling professionals to understand complex trade dynamics, manage cross-cultural risks, and identify international growth opportunities. These theories provide the analytical tools needed to optimize supply chains, enhance competitiveness, and formulate effective, sustainable global strategies.

The theories can be classified into: Classical Country-Based Theories: Mercantilism, Absolute Advantage, Comparative Advantage and Heckher-Ohlin Theory. Modern Firm-Based Theories: Country Similarity, Product Life Cycle, Global Strategic Rivalry and Porter’s National Competitive Advantage.

Mercantilism

It is a form of economic system and nationalist economic policy that is designed to maximize the exports and minimize the imports of an economy. It seeks to maximize the accumulation of resources within the country and use those resources for one-sided trade.

It is also known as “commercialism,” which is a system in which a country attempts to amass wealth through trade with other countries, exporting more than it imports and increasing stores of gold and precious metals. It is often considered an outdated system.

The biggest example being Passed by the British Parliament in May 1773, the Tea Act was a mercantilist policy designed to bail out the struggling British East India Company by granting it a monopoly on tea sales in the American colonies. It allowed the company to ship tea directly to America, bypassing merchants and reducing costs, while enforcing a three-cent tax to assert Parliament’s taxing authority. The Act aimed to save the financially troubled British East India Company by allowing it to dump 17 million pounds of unsold tea in American markets, creating a practical monopoly.  Ships carrying tea were also turned away or had their tea destroyed in New York, Philadelphia, and Charleston. The Tea Act was effectively the world’s first corporate bailout (often helping by paying money in difficult situation) the act was designed to save the East India Company from bankruptcy.

Mercantilist economic policies rely on government intervention to restrict imports and protect domestic industries. Modern-day mercantilist policies include tariffs, subsidizing domestic industries, devaluation of currencies, and restrictions on the migration of foreign labor.

Modern-day mercantilism in India is reflected in policies prioritizing domestic manufacturing, reducing import dependency, and fostering a trade surplus, often termed “neo-mercantilism” or economic nationalism. Key examples include the Atmanirbhar Bharat (Self-Reliant India) initiative, the Production Linked Incentive (PLI) schemes, high tariffs on imports, and the decision to stay out of the RCEP (Regional Comprehensive Economic Partnership)  trade agreement to protect domestic sectors.

Absolute Advantage

The ability of a country to produce more of a good with the same resources than another country is absolute advantage. India has an absolute advantage in the production of wheat over China and China has an absolute advantage in the production of cloth over India. Absolute advantage in international business occurs when a country can produce more of a good or service with raw material or technology which the country enjoys. It represents superior efficiency due to factors like better technology, climate, or lower labor costs.

Due to abundant oil reserves, Saudi Arabia can produce oil at a much lower cost and in higher volume than most countries, giving it an absolute advantage. China has historically held an absolute advantage in textile production due to a large workforce, lower labor costs, and efficient manufacturing capacity. Japan possesses an absolute advantage in high-end electronics manufacturing owing to its advanced technology and highly skilled workforce.

Comparative Advantage

It is the ability of a country to produce goods at a lower opportunity cost than another country by achieving  economies of scale. Reductions in average costs due to increased production levels. For example, China’s low labor costs give it a comparative advantage as a manufacturer over many Western trading partners. South Africa has a comparative advantage in mining because of its mineral wealth.

Brazil has a comparative advantage in coffee production due to climate, while South Africa holds an advantage in mining due to mineral abundance. Germany and Japan have a comparative advantage in automobile manufacturing and high-end machinery due to advanced technology and highly skilled labor, despite higher production costs. India has a comparative advantage in software development and IT services due to a large pool of educated, English-speaking, and cost-efficient professionals, which the U.S. imports.

Eli Heckscher and Bertil Ohlin Theory

It is also known as factor-proportions theory. Both prepared a theory explaining international trade patterns by focusing on differences in factor like cheap labor, raw material, and capital between countries, suggesting that countries export goods using their abundant, cheaper factors and import goods which are scarce.

Bangladesh specializes in clothing (labour-intensive), while Germany exports machinery (capital-intensive). A country with abundant labor (e.g., India) tends to produce and export textiles, while a capital-abundant country (e.g., Germany) specializes in automobile production. While South Korea was historically labor-abundant, it successfully transitioned to capital-intensive exports (electronics) by investing in infrastructure.

Modern & Firm based theories:

Raymond Vernon’s Product Life Cycle (PLC) theory

This explains how trade patterns shift as products evolve from innovation in developed nations to mass production and standardization in developing countries, moving through introduction, growth, maturity, and decline stages. The theory explains how a product’s production and trade patterns shift over time, eventually leading the original innovating country to become an importer of the very product it invented. As the name suggests, this theory talks about a product that goes through different stages. This theory only focuses on the developed nation, not on the developing nation.  According to this theory, when a product is in its early life cycle stage, all the raw material and the labor used in making and producing that product belong to the place where the product has been invented or produced. But when that new product is introduced in the world market, then its area of origin shifts to different places

PC Personal computer) were introduced to world by US; its mass manufacturing in low-cost Asian countries declined production in US. Now US purchases Pcs from Asian countries.

Country Similarity Theory (Steffan Linder)

Trade within similar development stages (intra-industry trade) occurs due to similar consumer preferences. states that countries with similar income levels, consumer habits, and industrial development trade similar, high-quality manufactured goods with each other (intra-industry trade). Key examples include massive trade in automobiles between Germany and France, or electronics between the US and Canada.

Global Strategic Rivalry (Krugman/Lancaster)

Firms gain competitive advantage through innovation, R&D, and economies of scale, influencing trade patterns. Competition for leadership in semiconductors, artificial intelligence, and 5G networks, often involving sanctions, export restrictions, and investments in critical infrastructure.

Porter’s Diamond Model

National competitive advantage stems from four interconnected factors: factor conditions, demand conditions, related/supporting industries, and firm strategy/rivalry. Germany’s automotive industry, showcasing strong national advantage through skilled engineers (Factor Conditions), demanding consumers wanting high-performance cars (Demand Conditions), a robust supply chain (Related/Supporting Industries), and intense rivalry between BMW, Mercedes, and Audi driving innovation (Firm Strategy/Rivalry).

The Easterlin Paradox, formulated by Richard Easterlin formulated in 1974, describes the evident contradiction between increased national wealth and increased average happiness levels. While individuals with higher incomes tend to report higher happiness levels within a specific time frame, a country’s average happiness does not necessarily increase over time as its overall income grows.  We apply common corelation between accumulated wealth and happiness.  People with higher incomes tend to be happier than those with lower incomes.

Despite the positive correlation within a point in time, the average happiness levels in a country do not consistently increase as the country’s overall income rises. This is the paradoxical part: while individuals may be happier at higher income levels, the overall happiness level of a country doesn’t necessarily follow fit as the country’s income grows. 

Richard Easterlin, then professor of economics at the University of Pennsylvania is the first economist to study happiness data. The paradox states that at a point in time happiness varies directly with income both among and within nations, but over time happiness does not trend upward as income continues to grow. Higher incomes don’t produce greater happiness over time. One explanation is that one’s happiness depends on a variety of other factors such as family and social connect, pollution less environment, hobbies of life, sufficient food, get together with friends etc.

In the short run, everyone perceives increases in income to be correlated with happiness and tries to increase their incomes. However, in the long run, this proves to be an illusion, since everyone’s efforts to raise standards of living lead to increasing averages, leaving everyone in the same place in terms of relative income. Various theories have been advanced to explain the paradox, but the paradox itself is solely an empirical theory. The existence of the paradox has been strongly disputed by other researchers.

Richard Easterlin has updated the evidence and description of the paradox over time. His most recent contribution is from 2022. This article is corelation between Easterlin’s Paradox and happiness index.  

According to the World Happiness Report and various other sources, Finland is consistently ranked as the happiest country in the world. In the 2025 report, Finland has been ranked number one for the eighth year in a row. Possibly, this happiness comes because Finns enjoy simple pleasures like clean air, pure water and walking around the woods, they enjoy their lives to the fullest. They enjoy a calm and peaceful life. it’s their appreciation for how things work and the ability to pause and admire the little things in life. In Finland, anyone can pick berries, collect mushrooms or fish with a simple fishing rod. It is part of  each citizen’s rights, which state that everyone is free to enjoy nature responsibly. Finland is cleanest in the world. The food that grows wild is delicious and fresh. Finding the luxury produce in the wild  like porcini mushrooms or cloud berries is considered a delightful moment and makes for an even more heavenly dinner. Finnish happiness is explained by the high levels of trust and freedom in its society, which research shows contributes to well-being and productivity.

In the 2025 World Happiness Report, Afghanistan consistently ranks as the unhappiest country in the world. Specifically, in the 2025 report, it is ranked 147th out of 147 countries. This ranking indicates that Afghanistan has the lowest happiness score and experiences the most frequent negative emotions, as well as the lowest frequency of positive emotions. 

The World Happiness Index Report is an annual publication of the United Nations Sustainable Development Solutions Network which contains rankings of national happiness and analysis of the data from various perspectives. The first World Happiness Report was released in April 2012. In a high-level meeting of UN well-being and Happiness were defined as new economic paradigms which drew international attention.

An Internet report suggested that if you want happiness, buy a scarf and gloves and head to Norway to experience real happiness.  Norway is well-known for its good public services and political stability. Denmark is another country which is famous for happiness nurtured in its culture. Danes have a stable government, little public corruption, and access to high-quality education and health care. The country does have the highest taxes in the world, but the citizens happily pay the taxes because they believe higher taxes can create a better society. Let’s understand what Happiness Index is.

What makes people of a country happy? Is it economy? Is it environment? Is it education? Is it government policies? We’ll all of these do contribute to people’s happiness in a country. But it is not necessary to be higher economic pace and growth always. People are happier when they don’t experience inequality in distribution of wealth; people don’t mind paying taxes when there is fairness in tax structure. People are happy when government practices transparency in the implementing policies. People want safety, people want welfare, people want gooinfrastructure, hygiene and people want good quality education.

Corruption undermines government revenue and, therefore, limits the capacity of the government to invest in productive areas.  Corruption distorts the decision-making in public investment projects. It’s been observed the higher the level of corruption in a country, the larger the share of its economic activity that will go subversive, beyond the reach of the tax authorities. Corruption discourages entrepreneurship and innovation; it only encourages inefficiency. It dislocates the human resources.  It creates uncertainty among the citizens. And it diminishes legitimacy in all walks of life and increases crimes.

In all countries there are rich and poor; but when the levels of inequality are low, and the welfare systems are strong, the citizens are happy. People don’t mind paying higher taxes for living a happier life.

The report primarily uses data from the Gallup World Poll. Gallup is a credible polling organization. It is respected highly in media. Nevertheless, all research including polling have some weaknesses which depend on the various methodologies and details of the poll and its questionnaires. Each research has few statistical limitations. Gallup ensures that each annual report is available to the public to download on the World Happiness Report website.

Happiness index is measured using parameters like Housing, Income, Work, Community, Civic Engagement, Education, Environment, Health, Life Satisfaction, Safety and Life-Work balance etc. Each report is organized by chapters that delve deeper into issues relating to happiness. The chapters also include mental illness, the objective benefits of happiness, the importance of ethics, policy implications which lead to subjective wellbeing. The report is based on how strong a country’s social foundation and social trust is.

Bhutan is one of the Buddhist Kingdoms in the World and so far, has preserved much of their culture since the 17th century. Even with globalization, Bhutan follows its Buddhist culture. It allows a certain number of foreigners into the country each year, and the two hundred dollars a day that must be paid by every traveller is a deterrent for many. Internet, television, and western dress were banned from the country up until ten years ago. But over the past ten years globalization has proved to be a challenge to this tiny nation. Things have begun to change, but they are trying to balance things in their own way.

Bhutan is the only country in the world that has a ‘GNH’ which is “Gross National Happiness.” The process of measuring GNH began when Bhutan opened to globalization. It measures people’s quality of life and makes sure that both material and spiritual development happen together in its citizen’s lives. Bhutan has balanced it rightly so far

Conclusion

Happiness is very important to both individuals and as a country. A happy individual is productive and creative. As human beings, although we possess cognitive abilities and are highly “thought” oriented, the quality of our lives is determined by our emotions. The Easterlin Paradox states happiness varies directly with income, both among and within nations, but over time the long-term growth rates of happiness and income are not significantly related. The principal reason for the contradiction is social comparison. A happy human is emotionally strong because happiness protects heart, it strengthens immune system, it helps in combating stress, it found that happy people have fewer aches and pains. The idea that “money can’t buy happiness” is a widely held belief, often attributed to the belief that true happiness comes from things like relationships, personal fulfilment, and a sense of purpose. .  In  the World Happiness Report 2025, India is ranked 118th out of 147 countries.
