There are many Software Development life cycle (SDLC) models that articulates series of steps, tasks, and dependencies for developing software [7]. T. Life-cycle cost analysis (LCCA) is a method for assessing the total cost of facility ownership. In this model, we can easily change requirements at later phases and can be incorporated accurately. In the Agile model, the work is done over small (2-4 weeks) iterations with having their own. In short, each software development life cycle comprises the following stages: requirement analysis, UX/UI design, development and testing, implementation, documentation, and maintenance. Some project management teams will merge, separate, or skip specific tasks, depending on the scope. They define a set of guidelines which are to be followed during the development. Among other traditional methodologies, the Waterfall, Iterative and Spiral models are the backbone of most software lifecycle models [4]. System/Software Development Life Cycle, SDLC -. Flexibility in requirements. Iterative Waterfall Model: The Iterative Waterfall model is probably the most used software development model. 3. The waterfall is a widely accepted SDLC model. In STLC, less number of members (testers) are needed. Software Development Life Cycle Models are frameworks used to design, develop and test the software. Standards allow customers to compare among and evaluate cloud providers [9]. As the name suggests, predictive SDLC assumes you can predict the complete workflow. Predictive (or waterfall) life cycle.
