Difference between water fall model incremental model?

Answer 1

Water fall model

1. waterfall model always attempt to start with full requirements
2. Waterfall model is linear process flow execution.
3. Each five framework activities in sequentially flow beginning with communication and culminating with deployment.
4. In this linear process you can't go back.
5. Doesn't response to resources.
6. Inefficient used of resources.
7. The waterfall model some time called the classic life cycle as well as linear process model/sequential model.
8. In waterfall model more time spend in documenting

Incremental model

1. Incremental model is process of repetitions developed in smaller chunks.
2. An iterative life cycle model doesn't attempt to start with full requirements.
3. This process is repeated

   producing a new version of software for each cycle of the model.

4. In this incremental process you can go back.
5. we are build the product step by step. W

   e can track the defects at early stages.

6. This avoid the down word flow of the defects.
7. In iterative model less time spend on documenting.
8. example:
