Managers have often to manage teams that they haven't chosen but they still have to do it.

They generally know how to communicate with two third of the members of their team.

The last third is consuming lots of their energy. There are many ways to deal with this last third: neglecting them, confronting them harshly and regurlarly, feeling guilty for not being able to deal with them...

When you understand the inner energy of each color, you save time and energy while getting good results with all members of your team. Managers have then time to choose members with different energies and then increase the individual and general results of their teams.
