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

The marketing mix encompasses the 4 Ps: product, price, place, and promotion, which are essential components for successfully marketing any product. However, it does not specifically address the stages a product undergoes throughout its existence, making it unrelated to the question's context about product lifecycle stages.

The marketing planning process involves the steps taken by a company to create a marketing strategy, including market research, segmentation, and positioning. While this process can utilize insights from the product life cycle, it does not describe the stages of the product itself but rather the planning activities a company undertakes.

Product width refers to the number of different product lines a company offers, which is a measure of variety rather than a description of the stages a single product goes through. This term is focused on product assortment rather than the lifecycle phases of individual products.
