What is the term used to describe the stages a product goes through?

The marketing mix refers to the combination of marketing tools used to promote a product, typically summarized by the four Ps: product, price, place, and promotion. While the marketing mix is essential for positioning and selling products, it does not specifically describe the stages a product goes through over time.

The marketing planning process involves the strategic planning steps a business takes to achieve its marketing objectives. Although it is crucial for overall marketing success, it does not focus on the life stages of a product itself. Instead, it encompasses broader activities, including market research and the formulation of strategies.

Product width refers to the variety of different product lines a company offers. It is a measure of the breadth of the product portfolio but does not convey information about the stages a single product undergoes from launch to decline. Thus, it is unrelated to the concept of the product life cycle.
