The Kolbs Theory
The first stage of the cycle is having an experience then you reflect on the experience so this is where you reflect on what went good and what went bad. Learning from the experience is the next stage so you can improve on your weaknesses and then trying out what you have learned is the last stage.
This theory helps us to improve on our experience that we've had and our weaknesses so we know what to do next time so this doesn't occur again.
