Showing Recent Changes for Company Procedures

Hey all,

I'm looking for some suggestions on different ways that we can display recent changes made to a company procedure, which are most often word documents. Many employees have been with the company I work for a long time, and miss simple changes made to a procedure; I am hoping to find a way to show any changes that have been recently made to the document.

I have played with Track Changes a little, but it seems that once they are approved they go away. 

Any tips on showing recent changes so the employees don't have to re-read the procedure every time there is a change?

Thank you!
