This learning unit on supervising in the system is one in the Choice Series, a self-learning development program for supervisors. Purpose stated for the approximately eight-hour-long unit is to enable the supervisor to understand organizations as systems, understand how authority and responsibility work in the workplace, distinguish between types of work relationships, and clarify the position of the supervisor in the system. An introduction provides an overview of the unit and lists unit objectives. Parts A through D contain informative material, activities and answer keys, self-checks and answer keys, and a summary. Topics include what a system is, the supervisor's position, results for others, and results through others. Part E contains performance checks--an end check to be completed alone and a tutor check and work-based project. Part F consists of a brief unit review, extensions (print sources of additional information, such as units or sections in books), and a list of references. (YLB)
