Leaders identify talents and groom these individuals for increased levels of execution by equipping them with skills for starting and finishing projects squarely. The most effective tool a leader uses to change individuals to prepare them for greater responsibility and creativity is coaching and mentorship.
The difference between coaching and mentorship is in both scope and duration. While coaching is for a limited time to enable the individual being coached acquire specific skills to perform an act, mentoring is a long term activity that is more encompassing.
The difference is in the aim of the two initiatives: coaching is to better what exists by helping the individual become a better performer, and mentoring creates a pathway for building creativity processes on a long term basis in order to link the mentee to facilities/institutions, and raise their profile.
