Product hierarchy in marketing and effects on Product Life Cycle of a Product

Product hierarchy– the concept

In marketing management, a product hierarchy is a framework for organizing products and services into a logical structure, from the most fundamental customer needs to specific, individual items. Developed by Philip Kotler, this model helps businesses understand how their products deliver value to customers and how they can be used to inform strategic decisions, such as new product development and branding.

The six levels of the product hierarchy

The product hierarchy consists of six levels, moving from broad needs to specific items:

Need family: The most basic level, representing the core need the product family addresses. For example, the need family for a mobile phone is communication and connectivity.

Product family: Includes all product classes that can satisfy the core need. This could include mobile phones, computers, and tablets for communication devices.

Product class: A group of products within a family with functional coherence, such as smartphones within the product family of devices.

Product line: Products within a class that are closely related by function, customer groups, or price range. An example is Apple’s iPhone line within the smartphone class.

Product type: A group of items within a product line sharing a specific form of the product. The iPhone 15 Pro Max is a product type in the iPhone line.

Item/stock-keeping unit (SKU): A distinct unit within a brand or product line, differentiated by features, size, or price, representing the specific item purchased. A 256GB, blue titanium iPhone 15 Pro Max is an example SKU.

Importance in marketing management

The product hierarchy is important in marketing management for several reasons:

• Customer understanding: It provides a customer-centric view by considering the core benefit customers seek.
• Inventory and portfolio management: It helps businesses organize and manage their offerings, ensuring new ideas align with the overall strategy.
• Product innovation: Marketers can identify innovation opportunities by considering potential future product enhancements.
• Market strategy and positioning: It aids in crafting effective marketing messages and positioning strategies by highlighting relevant features and benefits for target segments.
• User experience and SEO: A structured hierarchy improves website or app navigation and helps with search engine optimization.
• Competitive advantage: It assists companies in differentiating their products from competitors through unique features, services, and experiences.

3. How Product Hierarchy Affects the Product Life Cycle

• Need family level: Needs (like communication, food, transport) rarely decline, so products aligned with deep needs often have longer PLCs.
• Product family/class level: Shifts in technology can shorten the life cycle (e.g., the decline of landline phones in the communication family).
• Product line/type level: Within a line, one type might decline faster than another (e.g., sedans declining faster than SUVs in passenger vehicles).
• Brand/product item level: Specific items face the fastest cycle—new models replace old ones quickly (e.g., iPhone 14 was replaced by iPhone 15 within a year).

4. Key Implications

• Strategic planning: Companies manage product portfolios at different hierarchy levels to balance short- and long-life products.
• Innovation: To extend the PLC, firms often innovate within the product line or type.
• Brand management: At the item level, lifecycle management is most intense, requiring updates, rebranding, or discontinuation.
• Diversification: Operating at multiple hierarchy levels helps spread risk—if one product type declines, another can sustain growth.
• Portfolio Strategy: Understanding where products within the hierarchy are in their PLCs helps manage the entire portfolio. Mature products can support the introduction of new items.
• Targeted Management: The PLC guides specific strategies for different levels of the hierarchy, such as tailoring marketing for a particular product type or brand.
• Strategic Forecasting: Analyzing existing product PLCs aids in predicting portfolio performance, resource allocation, and planning for new product development.

 

Why PLC is Especially Relevant in India Today

• Rapidly Evolving Marketing: India’s market is characterized by fast-changing trends, with consumers quickly adopting new products and ideas. The PLC helps businesses identify these shifts and adapt their products and strategies accordingly.
• Diverse Consumer Base: India’s diverse population presents a complex market with varying needs and preferences. Understanding the PLC allows companies to tailor products and marketing to different consumer segments effectively.
• Intensifying Competition: As more domestic and international companies enter the Indian market, competition is increasing. Proactive PLC management helps businesses differentiate their offerings and stay ahead of competitors.
• Strategic Resource Allocation: The PLC guides businesses in allocating resources for different stages, from initial R&D and marketing to manufacturing and potential product updates. This ensures efficient use of capital for optimal returns.
• Need for Continuous Innovation: To maintain a competitive edge, especially during the maturity and decline stages, businesses must innovate. The PLC highlights the need for product improvements and new strategies to extend product life and avoid decline.
• Brand Building and Customer Loyalty: By effectively managing each stage of the product life cycle, companies can build stronger customer relationships and foster brand loyalty.
• Adaptability to Global Trends: The Indian market is increasingly influenced by global trends. The PLC provides a framework for companies to respond to these external factors and adapt their products and strategies to remain relevant.
• Rapid adoption + faster obsolescence: Products move through PLC stages more quickly (e.g., smartphones upgrade cycles).
• Diverse market: Some products may be in maturity in metros but still in growth in rural India.
• Innovation-driven competition: Indian startups and global brands use PLC insights for survival and growth.
• Regulation & sustainability: Government policies (like EV subsidies, plastic bans) accelerate PLC shifts.
