in a nutshell, IV is a documented process that all users of an instrument must follow. These guidelines are written in a very clear, easy to follow way so anyone can apply them. Consistency is of the utmost important when performing the validation of an instrument. The goal of the established guidelines is to make sure that all equipment is up to spec before any work is done. This allows all the operators of the equipment the peace of mind that all the work they are performing is at 100% capacity.
