Like Boyatzis (1982) before him, Ivancevich (1998) identified communication skills and other interpersonal skills as among the most necessary competencies for supervisors and managers. Integral to the management or supervision function in the view of both of these analysts are the functions of planning, organizing, controlling, motivating, and coordinating. Each of these managerial functions is accompanied by specific tasks and requires the deployment of specific competencies. For example, planning is a function involving such tasks as determining the goals of the organization and establishing action plans to achieve those goals. To succeed, supervisors and managers must possess the ability to use logic and systematic thought processes to identify and then solve problems (Boyatzis, 1982; Ivancevich, 1998).
