Software Development Life Cycle
Software Development Life Cycle: The software development life cycle begins with the identification of requirement for software and ends with the formal verification of the development software against that requirement. In V-Shaped model the development and testing phase are carried out parallel sequence i.e. Verification on one side and validation on other side. Advantage : As the verification and validation are done along with the test management. The outcome of V shaped model is a quality product. Drawback : Time consuming and costly model. Water fall model : in this model the development and testing phase are carried out step by step process and a base line document is prepared. Advantage : It’s simple model and easy to maintain, project implementation is very easy. Drawback : Can’t incorporate new changes in the middle of the project development. Base line document. Prototype Model (Rapid Prototype model) :- This is cyclic version of the linear model. In this model once
