I'm not quite clear on your situation. "Change control" is an an ambiguous term in that it can apply to something like:
- the orderly processing of a design change to a device
or, in a broader sense, to
- the orderly processing of a change to the operation of an entire organization.
Sometimes folks are a little bewildered by the need for a systematic process of
- (recognizing need for change) wanting a change in design or process (reasons can be myriad, ranging from cost to more effective product for end user.)
- (authoring) assigning an individual to draft the change, making sure ALL the allied processes will continue to match, sometimes making it necessary to change them, too.
- (approval) having other individuals check the changes to assure they are workable and match all other processes
- (issue) issuing the change, simultaneously withdrawing the previous version
- (notice & implementation) notifying all interested parties of the change and confirming they are aware and will implement the change
- (evaluation) evaluating the change down the road to assure it works as intended
Change for medical devices adds a special step in the approval process - making sure the change is notified to regulators and their approval added before issuing and implementing the change.
There are countless books, consultants, and courses (seminar type) which address the philosophy and/or management of change. Tell us more about your personal situation so we can narrow the focus of our answers.
