This means that for every single phase in development cycle there is directly associated testing phase. This is highly disciplined model and the next phase starts only after completion of previous stage. Advantages : 1. Very high stability of product. 2. Testing team is involved from the start. 3.

Waterfall model was the first software development process model to be introduced. It is also known as Linear Sequential Life Cycle Model. It is very easy to understand and adapt. There is no overlapping between the phases in this model. Every phase must finished before next phase can began. Applications : 1. For short and simple projects. 2. whenever requirement is not going to change. Advantages : 1. Easy to adapt and learn. 2. The product is highly stable. 3.
