We have a team that wants to use a wiki to store design documents for various applications. In PPM, we will have an approval process to review and approve the design documents. The need in PPM is to have a specific revision of the design document associated with the request so that the design document isn't changed mid-approval.
Is anyone currently doing anything like this? If so, are you linking to specific revisions of the wiki articles or are you extracting the documents then attaching to PPM? Have you had any other challenges?
