A study was conducted to describe the present status of self-managed work groups in Ohio manufacturing companies. Data for the study were gathered through lengthy interviews and site visits with 45 manufacturing companies in the state, 24 employing 2,000-14,000 workers and 21 employing 300 to 1,900 workers. The results of the study are presented in four separate reports contained in this document. They address the following subjects: (1) planning to use self-managed work groups, which answers questions about the planning processes used, goals that have been identified, the role of pilot areas, and training programs that are provided; (2) features of such groups, including what company structures and what features are used, the roles of steering committees and group leaders, and what other organizational changes have occurred; (3) results of using self-managed work groups, outlining what job and processes changes occurred, the organizational impacts, the perceived value of the change, and what would be done differently; and issues and implications that emerged during the study, such as the appropriateness of self-managed work groups, use of a broader change process, changes in compensation schemes, employee development as a goal, and allocation of resources. A list of participating companies is attached. (KC)
