Life Cycle Models for Software Development
Life Cycle Models for Software Development The life-cycle model is one of the key concepts of Software Engineering . A life cycle for a system generally consists of a series of stages regulated by a set of management decisions that confirm that the system is mature enough to leave one stage and enter another. We will talk about two main types of Life Cycles. The Product Life Cycle The Software Life Cycle 1. The Product Life Cycle The product life cycle is the pattern of stages that a new product or service goes through in its lifetime . Any product goes through a life cycle similar to living things. According to the product life cycle theory, products go through four defined stages: introduction, growth, maturity, and decline. Each product has a different curve on the graph for sales and time spent in each stage. THE PRODUCT LIFE CYCLE In the field of engineering, there are many sequences of stages that go through any product. In general, we ca...
