The Criterion Validity of Work Time Estimation Methods.
Tieger, Todd; Felfoldy, Gary L.
An increased need for better information about labor costs associated with many aspects of telephone company operation led to research by the Bell System on work time estimation methods. Several studies were conducted under different field conditions to test the concurrent validity of work time estimation data in comparison with two different methods of work measurement, i.e., work times derived from self-reports and work times derived from productivity measures. The basic approach of the studies involved: (1) analyzing and flowcharting work process; (2) gathering estimates of time for each discrete activity; (3) gathering data to assemble estimated work times for larger work process segments; and (4) gathering data to assess concurrent validity of work time estimates with the traditional methods of work measurement. Results showed that estimated work times predicted alternative measures of work time with varying accuracy; prediction of self-reported work times was very accurate while prediction of production-based work times was tentative. The findings suggest an overall pattern of robust prediction of criterion measures of "true" work time. (JAC)
