Once the code is developed they will release the build to the testing team where they will perform all the levels of testing. Once the build is stable it will be delivered to the client. The phases in SDLC will be performed in the form v shape, hence we will call it as Advantages: The testing activities are started from the requirement phase onwards so that we can ensure for quality. For each and every phase the verification team and validation team will check the phases so that we can ensure for quality. The risk can be identified at the early stage because we have a parallel testing activity, so it can be prevented. We can accept the requirement change at the middle of the phase. Disadvantages: It's a time consuming and costly process but we can ensure for quality. Fish model: It is same like v-model. In fish model we will have multiple Verification teams from the client and company to check the process and to provide more quality and security. It is more expensive than v-model. It provides more security and is applied in high level security projects like NASA, Air force, Navy, Army etc. Note: Validation team will review unit test cases results when the build is under development
