By definition management is getting things done through people. It is, and always has been, a team concept. A manager's beliefs about people determine his management style, and the style used in moments of stress is extremely important. The paper describes seven management styles-critical and demanding, supportive and encouraging, informed and problem solving, angry and put-upon, clever and manipulative, spontaneous and uninvolved, and combinations of these-stating that most managers use some combination of these styles. The relationship of managerial style to team effectiveness is then evaluated.
