What is a Product?
A product is any good or service that serves to satisfy the needs or wants of customers.
- Tangible products — physical goods (e.g. a phone, a car)
- Intangible products — services (e.g. a haircut, a streaming subscription)
- Consumer products — bought by individuals for personal use
- Business (B2B) products — bought by organisations for use in production or operations
The Product Life Cycle (PLC)
The PLC describes the stages a product goes through from launch to withdrawal.
| Stage | Sales | Profit | Investment | Cash Flow | Typical customers |
|---|---|---|---|---|---|
| Development | None | Negative (losses) | Very high (R&D) | Strongly negative | None yet |
| Introduction | Low and growing slowly | Negative or very low | High (launch marketing) | Negative | Innovators |
| Growth | Rising rapidly | Turning positive and rising | Moderate (brand building) | Improving | Early adopters |
| Maturity | High but slowing/stable | At peak | Lower (maintenance) | Strongly positive | Early & late majority |
| Decline | Falling | Falling | Minimal or divesting | Reducing | Laggards |
Each element of the marketing mix changes across the PLC. For example, pricing may be premium at launch (skimming) and then reduced in maturity; promotion is heaviest at introduction and growth.
Extension Strategies
When a product enters decline, a business may try to extend its life rather than withdrawing it. Extension strategies aim to halt or reverse falling sales.
| Strategy | How it works | Example |
|---|---|---|
| Price reduction | Attract price-sensitive customers who had not previously bought | Reducing a console's price years after launch |
| New markets | Sell the same product to a new geographic or demographic segment | Selling an existing product to a new country |
| New uses | Promote new ways to use the product | Arm & Hammer promoting baking soda as a fridge deodoriser |
| Rebranding/redesign | Update packaging, formula, or image | Updated packaging on an established food brand |
| Promotions | Increased advertising, sales promotions to re-engage customers | Supermarket deals, limited-edition versions |
| New distribution channels | Make the product available in new places | Selling online when previously only in-store |
Key question: Can extension strategies continue indefinitely? In principle, no — eventually a product may become obsolete, be replaced by a superior alternative, or fail to find new customers no matter the strategy.
BCG Matrix and the PLC
The BCG Matrix classifies products by market share and market growth rate, and maps roughly onto the PLC:
| BCG Quadrant | Market growth | Market share | PLC stage | Cash flow |
|---|---|---|---|---|
| Question Mark (Problem Child) | High | Low | Introduction | Negative — needs investment |
| Star | High | High | Growth | Broadly neutral — earns but also requires investment |
| Cash Cow | Low | High | Maturity | Strongly positive — funds other products |
| Dog | Low | Low | Decline | Low or negative — candidate for withdrawal |
Branding
A brand is a name, symbol, design, or combination of these that identifies a product or business and distinguishes it from competitors.
| Dimension | Meaning |
|---|---|
| Brand awareness | The extent to which consumers recognise and recall a brand — the foundation of all other brand dimensions |
| Brand development | The process of building and strengthening a brand over time through consistent messaging, design, and experience |
| Brand loyalty | The tendency of consumers to repeatedly purchase from the same brand — reduces price sensitivity and churn |
| Brand value | The financial and strategic premium a brand generates — the amount by which a brand name increases what customers are willing to pay |
A strong brand creates: barriers to imitation; customer loyalty; pricing power; credibility for new products; reduced marketing costs over time.
Packaging
This section is pending teacher review.
Packaging is more than a container — it is the last point of contact between the brand and the customer before purchase, and the first physical experience after it.
- Protects the product during storage and transport
- Provides legally required information (ingredients, safety warnings, country of origin)
- Enables handling and convenience (resealable, portion-controlled, easy to open)
- Attracts attention on the shelf or screen (colour, shape, typography)
- Communicates brand values and positioning at a glance
- Differentiates the product from competitors with similar contents
- Reinforces brand identity and supports premium pricing
Redesigning packaging can also function as an extension strategy — refreshing an ageing product's image without changing what's inside. Environmental considerations are increasingly important: whether packaging is recyclable, proportionate to the product, and whether sustainability claims are genuine or greenwashing.
The Marketing Mix and the Product Life Cycle
This section is pending teacher review.
Each element of the marketing mix should shift as a product moves through its life cycle:
| P | Introduction | Growth | Maturity | Decline |
|---|---|---|---|---|
| Product | Core product only; features still being refined | Variants added; quality improvements | Full product range; strong differentiation | Product range reduced; extension strategies considered |
| Price | Skimming (premium) or penetration (low) depending on strategy | May reduce as competition enters | Competitive pricing; price wars possible | Price cuts to clear stock or premium maintained for loyal customers |
| Promotion | Heavy spending to build awareness; informative advertising | Persuasive advertising; word-of-mouth growing | Reminder advertising; loyalty programmes | Minimal spend; targeted at remaining loyal segment |
| Place | Selective distribution; limited channels | Distribution expands rapidly | Intensive distribution; maximum availability | Distribution reduced; only most profitable channels retained |
Appropriate Marketing Mixes
This section is pending teacher review.
There is no single correct marketing mix. The right combination depends on the nature of the product, the target market, and the competitive context.
| Context | Key mix considerations |
|---|---|
| Goods vs services | Services rely more heavily on People, Processes, and Physical Evidence — the three extra Ps exist precisely because services are intangible, variable, and consumed at the point of delivery |
| B2C markets | Promotion and branding are central; emotional appeals matter; place (convenience and availability) is often critical |
| B2B markets | Personal selling and relationships matter more than mass advertising; price is negotiated; product specifications and reliability are paramount |
| Premium / luxury products | Premium pricing reinforces brand perception; selective distribution protects exclusivity; promotion focuses on aspiration |
| Mass market products | Competitive pricing; intensive distribution; heavy above-the-line promotion |
| New market entry | Penetration pricing and heavy promotional spend to build awareness; selective distribution until supply chains are established |
- PLC stages: Development → Introduction → Growth → Maturity → Decline
- BCG matrix: Question Mark (intro), Star (growth), Cash Cow (maturity), Dog (decline)
- Extension strategies delay decline — price cuts, new markets, new uses, rebranding, promotions, new channels
- Brand = name/symbol that identifies a product; brand value = premium customers pay for it
- Packaging serves both a functional and a promotional role
- The right marketing mix depends on context: product type, market, PLC stage
Question: With reference to CrunchTime (a granola bar brand moving from maturity towards decline), explain how promotion can be used as an extension strategy.
Model answer:
In the short term, promotion can attract and persuade customers to buy the granola bars again, helping slow falling sales. For example, limited-time supermarket discounts and free samples at school sports events encourage students to try a product they may have stopped buying — directly addressing the decline by stimulating trial and purchase.
In the long term, promotion can reposition the product in customers' minds, extending the life cycle by attracting new segments. For instance, CrunchTime could use social media marketing to link the bars to fitness culture — targeting adults aged 25–35 who value convenient nutrition — rather than relying solely on their existing teenage audience who are switching to "healthier" alternatives. This repositioning would require consistent messaging across multiple channels over time to shift brand perception.
However, promotion alone may not be sufficient if the core product has become outdated. Without a genuine product improvement or reformulation, customers attracted by promotion may try the product but not repurchase — making promotion only a short-term fix. A more sustainable extension strategy might combine promotion with product development (e.g. a new "high protein" variant) to give customers a genuine reason to switch back.
When asked about the PLC in an exam, always link it to the other elements of the marketing mix — not just sales. Examiners want to see that you understand how investment, pricing, and promotion strategy all change at each stage.
Draw a graph with time on the x-axis. Plot four lines: sales revenue, profit, investment, and cash flow. Label each stage of the PLC. Then annotate where different types of customers (innovators, early adopters, early majority, late majority, laggards) would first appear.
- How does each BCG quadrant link to the stages of the PLC?
- Why is the "Problem Child" also called a "Question Mark"? Which name do you find more useful, and when?
- A business has one Cash Cow, two Question Marks, and no Stars. What does this tell us about its product portfolio? What should it do?
Zenith Gear (ZG) manufactures fitness trackers. Its current portfolio:
- Titan 5: 40% market share in a market growing at 2% per year. Generates massive cash flow but requires little investment.
- Pulse-Z: 5% market share in a rapidly expanding (15% growth) entry-level market.
- Aura Ring: 2% market share in a high-growth sector (25% growth), launched six months ago.
- Zenith Classic: Market growth is negative; ZG's share is less than 1%.
- Categorise each product into the BCG Matrix and explain your reasoning.
