Software life cycle

According to Cem Kaner, "The full business, from initial thinking to final use, is called the product's life cycle." A life cycle is the sequence in which a project specifies, prototypes, designs, implements, tests, and maintains a piece of software. Explicit recognition of a life cycle encourages development teams to address development issues at the appropriate time; for example, to establish basic software requirements before design or coding begins. We recommend that developers roughly follow …

…without the entire project being abandoned. That is why incremental Model provides the approach which practice experience at users during a software process, and also provides the maintenance periodically.
