The development lifecycle of software Comprises of four major stages namely Requirement Elicitation, Designing, Coding and Testing. A software process model is the basic framework which gives a workflow from one stage to the next. This workflow is a guideline for successful planning, organization and final execution of the software project. Generally, the authors have many different techniques and methods used to software development life cycle. Project and most real word models are customized adaptations of the generic models while each is designed for a specific purpose or reason, most have similar goals and share many common tasks. This paper will explore the similarities and difference among these various models.
