The concept of the product life cycle

The product life cycle describes the progression of sales for a product over time, from its initial development through to its eventual withdrawal from the market.

Key terms in the product life cycle:

• Product life cycle - The pattern of sales levels at various stages that a product experiences over time.
• Skimming (also known as creaming) - Setting a high initial price for a product, which is later reduced.
• Penetration pricing - Introducing a product at a low price to quickly gain market share, with potential price increases once the product is established.
• Extension strategies - Techniques employed by businesses to lengthen a product's time in the market.
• Launch - The formal introduction of a new product to the market.

The five stages of the product life cycle

Products typically pass through five distinct stages, each characterised by different sales patterns, costs, and strategic considerations.

Development stage

Sales remain at zero while the product undergoes research, design, and testing. Businesses face high costs that can strain cash flow, with no revenue to offset expenses. Many products fail here, leading to potential loss of investment if the concept does not advance.

Introduction stage

The product enters the market, often marked by an official launch. Costs stay elevated due to investments in production setup and promotional activities.

Businesses may adopt different pricing approaches:

• Skimming - To target early adopters willing to pay more.
• Penetration pricing - To build a customer base rapidly.

Growth stage

Sales rise steadily for successful products, often showing a sharp upward trend. Revenue begins to cover earlier development expenses, potentially leading to profitability. Production costs tend to fall as economies of scale are achieved. The arrival of competitors can slow the rate of growth over time.

Maturity and saturation stage

Sales stabilise and eventually plateau as the market reaches capacity. The product generates strong profits, with development costs fully recovered and improved cash flow. Increased competition saturates the market, often driving down prices. Businesses may shift promotional tactics and introduce extension strategies to maintain interest.

Decline stage

Sales fall progressively until the product is discontinued. Factors such as evolving customer tastes, technological advancements, or superior rival products contribute to this downturn. Businesses typically phase out the product and introduce replacements to sustain their portfolio.

Different types of product life cycles

Not all products follow the same life cycle pattern; variations depend on the product's nature and market dynamics.

Fad products

These have extremely brief life cycles, with rapid sales growth followed by a swift drop-off. They are often seen in novelty goods, such as electronic toys or collectable items that capture short-term trends.

Long-established products

These maintain sales over many years or even decades, showing extended maturity phases. Examples include classic soft drinks or staple food items that become enduring market fixtures.

Extension strategies for products

Extension strategies aim to extend a product's maturity phase and prevent or delay decline. They involve adapting the product or its marketing to sustain consumer interest.

Common extension strategies:

• Expanding to new markets - Entering international territories to access fresh customer bases.
• Discovering new applications - Promoting alternative uses, such as a cosmetic firm branching from skincare to hair products.
• Updating the product - Making modifications, like a car maker refreshing a popular model with new features.
• Broadening the range - Adding variations, for instance, a food producer launching additional flavours.
• Altering appearance or packaging - Introducing new designs, such as a drinks company varying bottle sizes or styles.
• Promoting increased usage - Encouraging more frequent consumption, like a sauce brand suggesting uses across multiple meals.

Benefits of extension strategies

Implementing extension strategies can provide several advantages, helping businesses maximise returns from their products.
