In a multi-year study conducted at Stanford University, researchers examined the annual performance appraisals of hundreds of presidents and chief executive officers of Fortune 1000 companies, some of the most successful executives in every business or industry. This study revealed that top executives had two dominant qualities in common. The first was the ability to function well as a member of a team. When they were starting out, they were good team players, making valuable contributions to the teams they were on. As they were promoted to more senior positions, they demonstrated the ability to bring together winning teams of talented people and organize them to accomplish important goals and results for their companies.
