software life cycle

1. waterfall

   • INCREMENTAL LIFE CYCLE MODEL The Incremental life cycle model builds an iterative approach into the Waterfall model. Development projects are divided into several smaller,
     • Advantages of the Waterfall model As a formalized approach to software development, the Waterfall model is simple and easy to use.
     • Disadvantages of the Waterfall model Although the Waterfall model provides a good introduction to software life cycle models, its usefulness is limited.

2. V-SHAPED

3. Incremental life

   • The phase test plans are developed during each level of development, and once coding is completed
     • Advantages of the V-Shaped model Like the Waterfall model, the V-Shaped model is relatively simple and easy to use. Specific goals are defined for each phase
     • Disadvantages of the V-Shaped model The rigidity of the V-Shaped model makes it inappropriate for most projects. Like the Waterfall model, all requirements must be stated at the beginning of the project,
