We’re still talking about building your confidence and self-efficacy.
So far we have talked about Mastery and learning vicariously.   Today our topic is Coaching for self-efficacy.  If we are trying to push a team to achieve mastery in multiple tasks or job functions, we need to provide that team with effective coaching in the form of present and principled leadership.
The hallmark of an effective, professional, coaching leader is that they talk less and listen more.  That might not be what you see with sports coaches, but it’s what works best in a work environment.
Too many leaders think coaching is primarily about feedback, and we’re taught to always start with something positive before you destroy their morale with all the stuff they should be doing better.
Instead, remember that coaching is primarily about improvement.  To improve someone’s performance, they need to know what’s expected, so the coach helps the performer to set high standards that really challenge their skills. 
With any challenge, you should expect several failures because a good challenge exceeds their current skill level.  The coach supports the performer with the resources they need to build those skills.  That might be in the form of time or tools.
Coaching leaders also have to correct a performer.  We do this with compassion and again by asking questions and listening more.  Let the performer explain the result they got and what happened to get the result.  If they have failed, they know it.  You don’t have to point that out!  Help them reflect on their performance to find where things went wrong and what they could do better next time.  Again – talk less, listen more.
Finally, a coach is the main source of encouragement.  If we are setting challenges that drive higher performance, there will be lots of failures along the way.  The coach helps the team persist through those failures by encouraging them to try again and to keep finding new ways to try the work until they can achieve the challenge.
The relationships you build as a proper coach will last a lifetime.  Remember:  Challenge, Support, Correct, and Encourage.  Four key skills for coaches.  Four key skills for leaders.
