📦 The Product Life Cycle
The product lifecycle describes the stages a product passes through from development to withdrawal from the market. Each stage requires different marketing and pricing strategies.
The product life cycle shows how a product's sales change over time: Development → Introduction → Growth → Maturity → Decline. Understanding which stage a product is at helps businesses make the right marketing decisions.
🔬 Development
Product being created. No sales, high costs.
🚀 Introduction
Product launched. Low sales, high promotion spend.
📈 Growth
Sales rising fast. Profits begin.
🏆 Maturity
Peak sales. High competition. Profits plateau.
📉 Decline
Sales falling. Consider withdrawal or extension.
💡 Why Does the Product Lifecycle Matter?
- Different stages require different pricing strategies (skimming at launch, competitive at maturity)
- Promotion spend should be highest at introduction and at extension strategy points
- Cash flow is typically negative at development and introduction — positive at growth and maturity
- Businesses with a product at decline need to launch new products to replace revenue
📈 The Five Stages in Detail
🔬 Development
Sales: Zero — product not yet sold. Costs: High R&D expenditure. Cash flow: Negative. The business invests heavily in creating and testing the product before launch. Market research is done here. Risk is high — many products never make it to launch.
🚀 Introduction
Sales: Low and rising slowly. Profits: Usually negative (launch costs exceed revenue). Strategy: Heavy promotion to create awareness. Pricing may be high (price skimming for innovative products) or low (penetration pricing to build market share). Distribution is limited.
📈 Growth
Sales: Rising rapidly. Profits: Turn positive. Strategy: Expand distribution, maintain promotion spend. Competitors start entering the market, attracted by profits. Price may begin to fall as competition increases.
🏆 Maturity
Sales: At peak, then plateauing. Profits: Highest — but beginning to plateau. Strategy: Competitive pricing, promotion focused on differentiation from rivals. Market is saturated. Businesses fight to maintain market share. Extension strategies may be applied.
📉 Decline
Sales: Falling. Profits: Declining. Strategy: Price cuts to clear stock; reduce promotion spend; consider withdrawal OR apply extension strategy to revive the product.
🔄 Extension Strategies
Extension strategies are used to prolong the life of a product in decline or late maturity — delaying withdrawal and protecting revenue.
An extension strategy is any action taken to extend the sales life of an existing product that is entering decline — delaying the need to withdraw it from the market.
🔄 Common Extension Strategies
- Price reduction — attract price-sensitive customers who previously chose competitors
- New packaging — refresh the product's appearance without changing the product
- New markets — sell the product in new countries or new segments
- New uses — promote new ways to use the product (e.g. Lucozade repositioned from hospital drink to sports drink)
- Product modification — add new features or variants (e.g. diet versions, larger sizes)
- Increased promotion — new advertising campaign to remind lapsed customers
- New distribution channels — e.g. selling online for the first time
🎯 Marketing Mix at Each Stage
The marketing mix (4Ps) must adapt as the product moves through its life cycle.
📋 Product Lifecycle and Pricing Strategy
- Introduction: Price skimming (high price for early adopters) OR penetration pricing (low price to build market share quickly)
- Growth: Price remains competitive; competitors entering may force slight reductions
- Maturity: Competitive pricing — businesses fight to maintain share
- Decline: Price reductions to clear stock and retain any remaining customers
📣 Product Lifecycle and Promotion
- Introduction: Maximum promotion spend — building awareness from zero
- Growth: Continued promotion to maximise the growth curve
- Maturity: Promotion focuses on differentiation from competitors
- Decline: Reduced promotion OR major campaign as extension strategy
🏢 Product Lifecycle in Real Business
⚡ Lucozade — A Classic Extension Strategy
- Original positioning (1920s–1980s): A glucose drink sold in pharmacies for people recovering from illness — a niche, declining market
- By the 1980s the product was in clear decline — associated with illness, hospital visits and the elderly
- Extension strategy: Completely repositioned as a sports and energy drink — "Lucozade replaces lost energy"
- New packaging (bright, energetic colours), new target market (young active adults), new promotion (athletes, sport sponsorship)
- Result: Sales massively increased — a declining product became a growth product again

📱 iPhone — Managing the Product Lifecycle
- Apple launches a new iPhone model approximately every year — each new model essentially restarts the product lifecycle for that product line
- Introduction: High price (price skimming), heavy promotion, limited distribution
- Growth: Wider distribution, maintained premium price, competition begins from Android
- Maturity: Competitive pricing vs Samsung, Galaxy etc; promotion focused on differentiation
- Decline avoided: Previous iPhone models are discounted as new ones launch — serving price-sensitive segment

⚠️ Common Mistakes
- Confusing the stages — especially Introduction (low sales, high costs) vs Growth (rapid sales increase)
- Forgetting that cash flow is typically negative in Development and Introduction
- Not knowing the Lucozade extension strategy example — the examiner loves it
- Only naming one extension strategy — aim for two or three
📝 Model Answer
"Explain one extension strategy a business could use for a fizzy drink in decline." (3 marks)
"A business could use repositioning as an extension strategy by targeting a new market with updated branding and promotion (1), which means the product appeals to a group of customers who were not previously buying it (1), which could result in a revival of sales and an extension of the product's profitable life. (1)"
