The verification and validation is a sort of best efforts to ensure the software system is constructed without malfunction, but limited to software area, meaning there could be extension to system, hardware and interfaces. IEEE 1012, IEEE 7-4.3-2, NUREG/CR-6430 and NUREG/CR-6463 for coding guidance are major codes and standards. This is a source for standardization efforts for other domains such as aviation, railway, military and automobile which has their own codes respectively.
