In many life situations, much of our success depends on our ability to understand and act on the personality dynamics of situations. If I am working as part of a team towards a goal, how I work as part of the team depends largely on how my personality fits in with other team members, and how I modulate my communication and actions based on the personality of others. If I am trying to sell someone a product or an idea, my success depends largely on how I pitch to their needs and personality. Because of this, there have been several personality tests developed by various researchers, each with their strengths and weaknesses. Since I plan on using a personality assessment in my work with individuals and teams, I did some research into the most popular assessments and in this series of articles, I'll explain more about the one that I chose and why.
