This learning unit on organization systems 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 distinguish between responsibility and authority and see how they relate to each other, understand how responsibility and authority are affected by different forms of organization, and identify and compare formal and informal relationships within an organization. An introduction provides an overview of the unit and lists unit objectives. Parts A through C contain informative material, activities and answer keys, self-checks and answer keys, and a summary. Topics include a framework for organization, developing an organization, and relationships in organizations. Part D contains performance checks--an end check to be completed alone and a tutor check and work-based project. Part E 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)
