XS Global Models

The Software Development Life Cycle (SDLC) is a process used in software development to plan, design, build, test, and deploy a software product. The SDLC model defines a series of stages that guide the software development process. There are different SDLC models, each with its own set of stages. Some of the common SDLC models are: 1. Waterfall Model:  The waterfall model is a linear sequential model that follows a sequential approach in which the output of each stage becomes the input for the next stage. The stages in the waterfall model are Requirements, Design, Implementation, Testing, Deployment, and Maintenance. 2. Spiral Model:  The spiral model is a risk-driven model that focuses on addressing the risks associated with the software project. The stages in the spiral model are Planning, Risk Analysis, Engineering, Evaluation, and Maintenance. 3. Prototype Model:  The prototype model is an iterative model that focuses on building a working prototype of the software t...
