The document discusses the V-model, a sequential software development process where each phase must be completed before the next begins and testing occurs in parallel to development phases. It notes the V-model is simple, allows early defect detection, and works well for small projects with fixed requirements, but is rigid with no early prototypes and changes can require updating many documents. In conclusion, the V-model is best for small-medium projects when requirements are clear and resources are available, but high customer confidence is needed as there is risk with no prototypes.

- 2. V- model means Verification and Validation model. Just like the waterfall model, the V- Shaped life cycle is a sequential path of execution of processes. Each phase must be completed before the next phase begins. Testing of the product is planned in parallel with a corresponding phase of development.
- 3. Steps in the V-Shaped Model
- 4. Simple and easy to use. Testing activities like planning, test designing happens well before coding. This saves a lot of time. Hence higher chance of success over the waterfall model. Proactive defect tracking – that is defects are found at early stage. Avoids the downward flow of the defects. Works well for small projects where requirements are easily understood.
- 5. Very rigid and least flexible. Software is developed during the implementation phase, so no early prototypes of the software are produced. If any changes happen in midway, then the test documents along with requirement documents has to be updated.
- 6. The V-shaped model should be used for small to medium sized projects where requirements are clearly defined and fixed. The V-Shaped model should be chosen when ample technical resources are available with needed technical expertise. High confidence of customer is required for choosing the V-Shaped model approach. Since, no prototypes are produced, there is a very high risk involved in meeting customer expectations.
