In Course 7 - Develop Effective Teamwork and Enrich Work, you learn how to develop effective teamwork or group interaction, to get more done.
If you only focus on individuals, you miss the huge benefit of people working together, because there is a multiplier effect from effective teamwork. Obviously, when you have people working together, you encounter different personalities, preferences, and approaches. So, leaders need to know how to help individual members develop complementary relationships, reduce conflict, and collaborate for enhanced results. Of course, teams are not appropriate for all organizations, but any leader needs to know how to help individuals work together better and that is what you learn here.
