However, despite its advantages, the original method suffers from a certain rigidity that complicates its use for small projects. This is why the V-cycle has evolved to become the " XT V-cycle " for " Extreme Tailoring " in English, meaning extremely flexible. Much more flexible, the XT V-cycle can now integrate an Agile approach since it involves the client from the design phase. In addition, it can finally be easily applied to small projects. In fact, the XT V-cycle is so popular for complex systems that it has become the standard in almost all industrial sectors.
Thus, the V-cycle method includes three main phases:
Design phase : The design phase forms the left side of the V-diagram and is the top-down flow. After a thorough analysis of the customer's needs, the finished product is designed from the synthesis of customer requirements to the detailed design of each of the individual components of the final system.
The implementation, located at the meeting point at rcs data romania the bottom of the V, is the stage where each component necessary for the product is actually developed according to the specifications established during the design phase.
Validation phase : The validation phase follows the right branch of the V, which is the ascending flow. It includes various tests to ensure the quality and conformity of the product with the initially defined functional specifications.
