Partially funded by a research grant from the Department of Health, Education, and Welfare, this technical monograph is the first of a series to be published on production-management aspects of vocational rehabilitation workshops. In order to meet information needs in this area, selected techniques used by industrial profit-making enterprises which are useful for workshops are described. The role of work measurement is discussed in resolving problems associated with the functioning of workshops as both a business and a social service. An overview of work measurement techniques for sheltered workshops is presented, focusing on: (1) its conceptual framework, (2) expressing the results, (3) methods of setting production standards, (4) applications for work measurement, and (5) its usefulness as a tool in process evaluation, job placement, and for use with the modified production standards concept. Task definitions, time values, and worker definitions are taken into account. (AG)
