The idea

Extension strategies aim to lengthen the life cycle of a product that is reaching maturity or decline. Common approaches include modifying the product, changing packaging, finding new market segments, targeting new geographical markets, refreshing promotion or adjusting price. Effectiveness depends on whether the strategy generates enough extra sales and contribution to justify its cost, and whether it fits the brand and the target market. For example, a soft drink brand might launch a sugar-free version to attract health-conscious consumers, extending maturity sales. Suitability varies: extension may work when the brand is strong and demand still exists, but it can fail if the product is obsolete, if competitors have moved on or if the spend merely delays an inevitable decline.

What earns the marks

• Identifies extension strategies such as product modification, new packaging, new market segments, new geographical markets, promotional refresh and price changes.
• Explains how an extension strategy can lengthen the product life cycle by sustaining or increasing sales during maturity or decline.
• Assesses effectiveness by comparing the extra revenue and contribution generated with the cost of implementing the strategy.
• Evaluates suitability in context, considering the strength of the brand, the nature of demand, competitor activity and the product's stage in its life cycle.
• Reaches a supported judgement on whether extension is worthwhile or whether the business should instead let the product decline or replace it.

Common mistakes and how to put them right

• Confusing extension strategies with launching a brand-new product.

  Put it right: Extension strategies modify or reposition an existing product to prolong its life cycle.

• Assuming any extension strategy will succeed.

  Put it right: Evaluate costs, demand and competition, and to recognise that some products cannot be revived.

• Describing an extension strategy without linking it to the product life cycle.

  Put it right: Explain how the strategy affects sales at the maturity or decline stage.

Exam tips

• Use a specific product example, such as a breakfast cereal adding a new flavour or a car manufacturer updating a model, to show how extension works in practice.
• Structure the evaluation by weighing benefits against drawbacks and then stating a clear, justified conclusion about suitability.
• Refer to the business context given in the case, including its objectives, target market and competitors, rather than giving generic advice.
