Which are the stages of the product life cycle?

• A. Introduction, Growth, Maturity, Decline
• B. Development, Launch, Saturation, Sunset
• C. Inception, Expansion, Optimization, Obsolescence
• D. Seed, Growth, Harvest, Renewal

Answer: (A)

The stages of the product life cycle are Introduction, Growth, Maturity, and Decline. This sequence mirrors how a product typically progresses in the market, with each phase bringing its own objectives and challenges. In the introduction stage, the goal is to build awareness and encourage trial, since many potential customers haven’t heard of the product yet and sales are modest. During growth, demand accelerates, sales rise quickly, and profitability improves as economies of scale kick in and distribution expands. In the maturity phase, the market becomes saturated, growth slows, competition intensifies, and marketers often focus on differentiation, loyalty, and efficiency to defend share and margins. Finally, in the decline stage, demand wanes due to shifts in consumer needs or technology, leading to declining sales and often a decision to discontinue, reinvent, or harvest the product.

Other phrasing like Development, Launch, Saturation, Sunset or Inception, Expansion, Optimization, Obsolescence uses terms that aren’t the standard sequence of stages used in this model, and they describe conditions or alternative concepts rather than the classic four-stage progression. Likewise, terms like Seed, Growth, Harvest, Renewal align more with broader business life cycles than with the established product life cycle.
