8 Fundamental SDLC Models Every Developer should know about Planning your “to-do” list is always a good idea. It can save time and keep you informed about any last-minute changes. It is indeed true for software development projects as well. In fact, some fundamental software development models can simplify a developer’s job to a large extent. Developing and maintaining software is a rather complex process with multiple stages. Software Development Life Cycle (SDLC) models are a set of structured models that guide the developers during the formidable stages of software development. These SDLC models take various attributes, including project objective, timeline, budget, stakeholders’ feedback, etc.
1. Waterfall Model The Waterfall model is probably the simplest software development model. As its name suggests, this model has been inspired by a natural phenomenon – waterfall. Like any waterfall, this particular SDLC model maintains a linear approach throughout. Developers who follow this web development model believe in completing and documenting the scheduled tasks in each phase as they continue to move downward.
2. Incremental and Iterative Model The incremental and iterative SDLC model takes an evolutionary approach when it comes to developing software. Under this software development model, the initial stage starts by creating a product with a limited set of considerations and requirements. Afterward, the developers keep developing the product with new iterations. Each of these iterations adds new features/design updates to the product.
3. V-shaped Model The next SDLC model in our list is the V-shaped model, also known as the Validation model. It is like an extension to the Waterfall SDLC model. If you’re following the V-shaped model for your software development process, you’ll see that progress doesn’t move in a straight line here. Instead, it rides in the upward direction after the implementation and coding stages.
