5. Differentiate between V-shape model and spiral model.

Answered by Sneha

The difference between V- model and Spiral model are as follows:- V - MODEL 1. V model is software development model but development and testing are not concurrent. 2. In V-model testing activities start with the first stage. 3. Cost of V-model is expensive. 4. Flexibility of V model is little flexible. 5. Guarantee of success through V model is high. 6. User involvement in V-model is also only in beginning. 7. It is not iterative. Spiral Model 1. Spiral model is a software development model and is made with features of incremental, waterfall or evolutionary prototyping models. 2. Testing is done in spiral model at the end of the engineering phase. 3. While cost of spiral model is also very expensive. 4. Flexibility to change in spiral model is not that difficult. 5. Guarantee of success through Spiral model is low. 6. In this user Involvement is only at the beginning. 7. It is iterative
