The article presents information about a model to improve human performance. Wilson Learning Worldwide Inc.'s Integrated Leadership Model is the essence of leadership character. Although some people think that leadership character can't be developed, the Wilson white paper asserts that not only can people develop it but also they must be in order to improve leadership performance. Doing so means "getting leaders to acknowledge their value systems, to increase their self-awareness, to experience the impact of character in their lives, and to break old patterns of thinking." The Integrated Leadership Model groups the skills for effective leadership into four distinct roles: Visionary, Facilitator, Contributor and Tactician. Each role has a unique mission and tasks to achieve it. The Visionary sets direction; the Tactician puts plans and processes in place; the Facilitator ensures that team members and stakeholders are on board; and the Contributor makes sure the leader's own talents are being used. A leader's ability to integrate the four roles, added to the foundation of leadership character, has a dramatic influence on workers' performance.
