Computer System Validation (CSV) is a core requirement for several industries. The aim of Computer System Validation is to ensure, through documentation, that the computer systems function the way they are intended to, consistently, repeatedly and reproducibly, somewhat in the manner expected of scientific experiments. So, the validation, meaning authentication or corroboration, is something that has to be done right from the start, that is, defining the computer system, to their use and going all the way right up to the time the computer system is retired.
