Creativity Question:

Training someone to develop their creativity is similar to how we would train someone to play tennis.

A tennis coach would start by diagnosing your approach - they would ask you to hit some balls, serve a few and examine your backhand and forehand. They would then develop a customized program to address weaknesses and build on your strengths.

This principle of a diagnosis before training should also be applied to training and developing creativity.
After a diagnosis each person or team can choose creativity tools and exercises that play to their strengths and develop their weaknesses.
