Changes "Sign-off" for documents related to my position

When a process, subprocess, or task instructions related to my position changes, I should be notified of those changes and sign off that I have read and understood the changes. The owners of the processes, subprocess, or task instructions should be able to monitor who has signed off that they have read and understood the changes. This feature is dependant on a feature that allows users to see the differences between the previous version and the current version with changes.
