The basic mission of the Office of Manpower Utilization (OMU) of the U.S. Marine Corps is to conduct Task Analyses of Marine Corps Occupational Fields. In its desire to maximize its effectiveness, OMU requested an independent evaluation of its program. This report summarizes studies and results of part of that evaluation, Research Area 5, "OMU Organization and Personnel," one of eight research areas into which the study was divided. The basic tasks of Research Area 5 were to discover, describe, and evaluate OMU policies and procedures relative to organization, task analysis, team assignment and structure, and team member procurement; identify indications of less than optimal performance and alleged deficiencies; design and evaluate experimental alternatives and/or modifications; summarize problem areas and report findings from experiments; identify and evaluate options in change and prepare recommendations for action. This report is a frank discussion of methods and phases of the study, findings, changes that occurred as a result of feedback during the study, and recommendations for future actions. Organizational structure at the beginning and end of the research are shown. (Author/WL)
