Abstract - Agile methodology is an approach used for the development of a project which helps to respond to the unpredictability of building software through incremental, iterative work cadences. But nowadays developers face various problems while using it to develop a software. Each incremental part is developed over an iteration. Please use, generate link and share the link here. Each iteration involves a team working through a full software development life cycle including planning, requirements analysis, design, coding, and testing before a working product is demonstrated to the client. The agile model is a combination of both incremental and iterative models and promotes more involvement of customers during software development. Toward the beginning of each … A software development life cycle (SDLC) model is a conceptual framework describing all activities in a software development project from planning to maintenance.
