The authors investigated how work requirement manhour estimates affect Air Force Civil Engineering productivity ratios by gathering standard and adusted estimates for five hypothetical work requirements and selected planner and work center data from a sample of Civil Engineering planners and work centers. The authors conclude that practical and statistically significant variation exist in standard and adusted estimates. Stepwise multiple regression using estimating criteria, planner data, and work center data as independent variables failed to reveal any assignable causes of the variation in either standard or adjusted estimates. The authors further conclude that variation in standard estimates is due to the planners inconsistent application of Engineered Performance Standards and that variation in adjusted estimates is due to the large number of different adjusting criteria used, subjectivity in their application, and the presence of variation in standard estimates. The authors observe that Air Force Civil Engineering does not appear to have a valid measure of productivity because of the use of adjusted estimates. The authors further observe that the variation in standard and adjusted estimates invalidates work requirement programming and cost estimating, work force scheduling and any attempt to measure productivity.
