  - 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.
