SDLC_Model_Incremental

Incremental Model

1. This model is viewed as a modification to the waterfall model.
2. Divide the large projects into smaller components, which many be developed incrementally and iteratively.
3. Provide a certain amount of risk containment.

• Advantages

1. Customer value can be delivered with each increment so system functionality is available earlier.
2. Early increments act as a prototype to help elicit requirements for later increments.
3. Lower risk of overall project failure.
4. The highest priority system services tend to receive the most testing.

• Disadvantages

1. Make the decoupling of the parts into independently implementable components difficult.
2. Require a deep understanding of the problem, the solution, and the usage environment.
