Coordination, communication, and basic awareness of what is being mapped are what we had to do. Just some best practice hints that I learned:
1) Define a set of standards for name mapping so that all users are using the same general rules
2) Make sure you are not including in your name mapping anything that is environment specific. As mentioned, IP addresses that are local to the current machine, user names, user profile directories, etc, should be avoided unless you have a generic envirornment that is common for everyone.
3) Use "Find" methods whenever possible within your script code and keyword tests. That way you will mind map only those things that are "static" throughout your tests and then use the "Find" methods to grab those more dynamic and volatile components.
