This paper investigates the association of leadership roles’ competencies as well as managerial effectiveness profiles with gender and job outcomes (job satisfaction and performance). In addition, the influence of leadership competencies on individual effectiveness of managers is explored, providing a course for action toward managerial excellence. Drawing upon a sample of 132 male and female managers in Greek firms, a structured questionnaire was developed adopting the Competing Values Framework (CVF) in order to measure both leadership roles’ competencies and managerial effectiveness.

revealed that managers characterized by high levels of job performance excel in practicing all leadership competencies, while gender does not exert significant impact. A similar pattern emerged for managerial effectiveness profiles. Moreover, leadership competencies associated with the innovator, director and mentor roles found to contribute most to managerial effectiveness, thus specific directions for managerial action has been derived.
