Our team has had our control systems mentor spend an entire day(s) during build season at other schools, the last several years.
Or our machinist make simple parts for other teams, due to the lack of resources of the other school, while they observe and learn the process of making them.
I'd constitute that as mentoring and not just providing advise on what the team should do.
If at some point, the team cannot be successful without the assistance of the team offering its assistance while teaching them something, I'd call that mentoring. If its reciprocating, then perhaps the term partnership or collaboration might be more appropriate.
