The four stages Introduction, Growth, Maturity and Decline describe which concept?

• A. Market Segmentation
• B. The Marketing Mix
• C. Competitive Pricing
• D. Product Life Cycle

Answer: (D)

Think about how a product goes from being new to the market all the way through to being withdrawn. The four stages Introduction, Growth, Maturity and Decline describe the Product Life Cycle. In Introduction, sales start slowly as people first learn about the product and costs run high from development and promotion. In Growth, sales rise rapidly as more customers buy and the business benefits from economies of scale. In Maturity, sales peak or grow slowly because the market is crowded and competition is strong, so firms push on features, branding, or price to maintain demand. In Decline, sales fall as market preferences shift or new alternatives emerge, leading to reduced investment or discontinuation. This sequence specifically maps the life of a product over time, rather than other concepts like dividing markets (market segmentation), the overall Marketing Mix, or pricing strategies.
