I believe it is more than the mentors.

As a mentor myself I think there is more than being good. But for engineers it is the ability to recycle the knowledge, establish and pass on good processes, examine where organization can improve and above all else remember that we all work together.

The process is important documentation of what a team does from year to year will help the team grow and improve. Thus within a few years a team will know what works and what does not. Helping to improve the general planning.
