What are the stages of the product life cycle and strategic implications for marketing?

• A. Introduction, growth, maturity, decline; affects pricing, promotion, distribution, and product updates.
• B. Growth, decline, introduction, maturity; affects only packaging.
• C. Introduction and growth only; marketing strategy does not change later.
• D. Maturity, introduction, growth, decline; no effect on product updates.

Answer: (A)

The product life cycle describes how a product moves through four stages—Introduction, Growth, Maturity, and Decline—and each stage calls for different marketing actions across the mix. In the Introduction stage, sales are just starting, costs are high, and you focus on building awareness through promotion and selectively distributing the product while experimenting with pricing. In Growth, demand accelerates, you widen distribution, differentiate your offering, and adjust pricing and promotions to capture market share. In Maturity, sales peak and competition intensifies, so you emphasize cost-efficient distribution, competitive pricing, and promotions that defend share while considering product updates or line extensions to keep interest alive. In Decline, demand falls, and you trim costs, reduce the assortment, scale back promotion, and may discontinue or harvest the product while focusing on the most profitable options.

This perspective explains why the best answer lists all four stages and acknowledges that pricing, promotion, distribution, and product updates are affected as the product progresses. The other options miss or misorder stages, or wrongly limit the scope (such as only packaging or suggesting no changes to marketing strategy at later stages).
