Frank Dick one of my mentors shared this basic concept to give a context to debrief of training or performance.
Why are you doing what you are doing?
What exactly are you doing? Is that reconciled with the reason?
What did you learn from what you did? Be as specific as possible here.
What are you going to do differently? This should consist of specific actions based on the reflection.
This is a simple process that can be used to make your daily coaching more effective.
