The general procedures and program files of the quality manual are the requirements of broadening the operation process, and compatibility is irrelevant. If some contents of the quality manual and procedure documents are changed once (individually), even if it is the first time, the date will be indicated and a revised resume will be made. Unmodified files should be marked with the original state. Of course, in order to maintain unity, some of them don't need to make all the amendments, which is a waste of resources.
