When dealing with worksets communication is critical.
You need to be able to communicate with your colleagues so there is no overlap of duties and that everyone is all "on board" with how the Job Captain wants things done.
Remember the Job Captain (or Project Leader) assignees who does what however there is occasional overlaps where some people may need to temporarily adjust worksets owned by other people.
I have found that the Revit Editing Request process is too slow so in our office we looked for another messaging process. We looked for a faster messaging system but didn't want to go with a open Web messenger such as MSN. so we found a LAN messenger that seems to work really well for us.
Squiggle is a free (I love that!) open Source (I also love that) LAN Messenger program that looks and feels similar to MSN, it's easy to set up and easy to use. http://squiggle.codeplex.com/
With Squiggle we can send requests for workset editing as well as send messages about the project etc much quicker.
Seems to be working great for us. :-)
