Artifact is generally used to represent cohesive information that is created and reviewed as a single entity. They compare the different software development models that have been carried out in this paper, the mathematical approach cannot be made with certainty the value or physical in the present age of the software system models are incomplete. In the Agile model, the work is done over small (2-4 weeks) iterations with having their own. A life cycle model map the different activities performed on a s/w product from its inspection to retirement. This study make SDLC selection process easy and effective for the system. Different types of projects life cycle model. Software quality models play an important role in the measurement of software quality. As its name recommends, developers and operations teams work together as a single team. Documentation focuses on the end product not the evolution of the product. It is important to note that SDLC may have different forms depending on the model (eg. An Agile startup methodology is a specific approach to managing projects applied in the development of a software. the coding of the application logic. In stark contrast to the fixed nature of the V-shaped model, Agile embraces the chaos and flexible nature of software development. It is concerned with the software management processes that examine the area of software development through the development models, which are known as software development life cycle. In this paper we compare software. PDLC consists of identifying a problem or. different models of software development and make a comparison between them to show the features and defects of each model. Software made using Waterfall model, the number of defects are less in comparison of software. There is a misunderstanding that commonly affects project managers working on software development projects: Many believe that PMI's PMBOK Guide supports only a non-agile, waterfall approach to managing projects.
