They’re all skills. You measure them the same. What if you wanted to improve your coaching skills? Why? You increase the effectiveness of those who work for you?
What happens now? You give others the answer or do it for them. What if you trained them to do it themselves through your improved coaching?
How much do you make? How much of your time do you feel you spend giving answers or doing something for someone else you are paying to do a job for you?
How much of your time do you want to recapture if you could improve your coaching? 10%?
We have just made improving your coaching skills measurable (tangible, intangible and periphery value).
