A good coach puts some pressure on you to do better and demonstrates his belief that you can do better in you. But more than that, the coach makes sure that what is expected of you is clearly communicated so that you have a clear vision of yourself accomplishing it. The ‘video’ that can be played in your head is important. If the resolution of this video is poor, then it is harder for the coachee to perform. And putting pressure on the person by reminding him or her of the deadline or final prize is pointless.
A coach doesn’t review a race with the runner telling that him or her that at different point of the race, how far or near he/she is still from the finish line. He tells the runner about his or her gait to improve, the rhythm of breathes. The how is more important than the what; but the why even more so. The good coach then reminds the runner of why he or she is running.
It is not possible for managers to help a team thrive without these coaching capabilities. Most managers would just be churning output without developing the team or sustaining the right motivation for the team to go on. Often this could lead to burn-out and poor morale. This is where a strong individual contributor needs to learn new skills to move into manager position and not thinking that he or she can just keep doing what they are good at.
