    - The above statement is true.

    - The product of testing is planned in parallel with a corresponding phase of development.

    - V-V model means Verification and Validation Model, just like waterfall model, but its execution process is different from waterfall model.

    - It has a sequential process path of an execution of processes.

    - Each phase must be completed before the next phase begins.

    Advantages of V-V model :

    - It is simple and easy to use.

    - Testing activities like planning, test designing happens well before coding. This saves a lot of time and has higher chance of success over the waterfall model.

    - It avoids the downward flow of defects.

    When to use V-V model :

    - It should be used for small to medium sized projects where requirements are clearly defined and fixed.

    - It should be chosen when technical resources are available with needed technical expertise.
