What does the life cycle of a product mean?

Product life cycle is a theory related to a product of the company first introduced in the 1950s. This theory was formulated to explain the expected life cycle of a typical product. It covers the entire lifecycle from the start to its ending, a period divided into the 4 phases of product. It includes introduction, product growth, maturity, and decline.

The main motive of this theory is to optimize the value at each stage of a product. It is a marketing theory.

Product Life Cycle Stages

Introduction Stage – This is a stage wherein the product is introduced in the market. This stage is preceded by ample research and study of the market. In this stage the product might not sell out at its best so, it may incur losses. This is a risk-taking stage. Promotion and advertising plays an important role.

Growth Stage – In this stage, the company grows. The sales increases and the company begins to benefit from the profit margins and the overall amount of profit, will increase. Thus, investment increases and the product is given a boost in this stage.

Maturity Stage –The product is well established during the maturity stage. Now, the aim for the manufacturer is to maintain the market share. This stage is characterized by competition and wise investment strategies. Innovation and modification is needed here.

Decline Stage – It so happens that the product in the market, its demand begin to shrink. This is called as the decline stage. This generally happens because the product has reached the level of saturation and the customers are or may have stopped buying the product. This happens usually when people get bored of the same product, or a better product comes in the market with less price and better technology. This is the final stage for a product.

  • The theory does not talk about product redesign.
  • There is nothing said about reinvention of a product.
  • There is no evidence which says that all products must die. Some products can mature again from decline stage. There are exceptions always/
