Software Development Life Cycle

Software Development Life Cycle

1. Waterfall Life Cycle Model

   • Advantages of the Waterfall model
     • easy to use. This model can be easy to implement and manage because each phase has an El development occurs in one phase at a time.
   • Disadvantages of the Waterfall model
     • its usefulness is limited. Due to the rigidity of the model, all requirements must be declared explicitly before development begins

2. Software Development Life Cycle Model

   • Implementation
     • This facet takes care of what was done in design that aga reality as it passes to decoding.
   • Design
     • is in charge of machining and designing the sofwar
   • Testing
     • this part already takes care of putting everything that iso formerly iso ready
   • Requirements-gathering
     • is in charge of managing the users that have or use the plaraform

3. V-Shaped Life Cycle Model

   • Advantages of the V-Shaped model
     • The rigidity of the V-shaped model makes it unsuitable for most projects. Like the Cascade model, all requirements must be established at the beginning of the project, making it possible to difficult to add or change requirements later in the development process
   • Disadvantages of the V-Shaped model
     • Like the Waterfall model, the V-shaped model is relatively simple and easy to use.

4. Spiral Life Cycle Model

   • Advantages of the Spiral model
     • The risk avoidance approach makes the Spiral model ideal for large-scale missions. products critics. At its core, the Spiral model is based on a previous software development and is taken from the models Waterfall and Incremental
   • Disadvantages of the Spiral model
     • The spiral model can cost considerably more than other life cycle models. The phase of Risk analysis requires a high degree of specialization and project success. depends on the output of this phase. The Spiral model is not suitable for use in small and medium-scale projects that are not suitable for small to medium-size projects. are mission-critical.

5. Incremental Life Cycle Model

   • Advantages of the Incremental model
     • Unlike the Waterfall and V-Shaped models, the Incremental model generates an operation prototype in the early stages of the development process. The iterative nature of Incremental makes more flexible when adding or modifying requirements.
   • Disadvantages of the Incremental model
     • Like the Cascade model, the Incremental model exhibits some rigidity in those phases cannot overlap. Because the requirements gathering and design are done during each iteration and not before development begins, the projects developed using the method
