If your goal is to level up the performance of a senior leadership team. There are many models and frameworks available to assess team behavior and performance. Each of them has pros and cons in different situations.
One of my favorites comes from the psychologist David Kantor and is called the Four-Player Communication Model. It applies to any team solving problems and collaborating to reach common goals. Each role is fairly simple to understand, yet getting them working together on a team can be a balancing act.
