I may be misunderstanding your question, but revised documents should always be updated. If any other document references the changed document, then that document should also be checked for any necessary changes. No document should be outdated, especially in a heavy FDA regulated industry. Outdated documentation can lead to safety issues and problems during a future audit. However, if you are speaking about an automated system that updates all preceding documents then that can be a time saver. However, these documents should also be check for accuracy and any other necessary changes.
