I-CONTEXT

The product life cycle (PLC) concept suggests that a product passes through four stages of evolution. As a biological circle or a human being’s life, a product has got several phases: conception, introduction, growth, maturity and decline. PLC can be defined as the analysis of the great steps of his life: from his concept to the final decision to withdraw it from the market. A product evolves and passes through theses stages, its profit is affected and different strategies have to be employed to ensure that the product is a success within its market. The product life cycle is a rudiment of the evolution of a product through the space.
