It is not an instantaneous program. It does not try to communicate great revelations but, on the contrary, it encourages reflection, analysis of your own behavior and of conduct seen in leaders. Above all, it puts into practice what is learned for the purpose of making you a good leader.
Basically, it is a personal and professional growth program. And, even better, the improvement is evident as well as subtle. You become a better leader without realizing it! Your collaborators will take notice, your company will take notice and (in this order) you will take notice.
