Document Summary

Perfect consistency is impossible, but rating procedures applied to different operators employing the same method that yield standards deviating less than 5% from the mean are considered adequate. Consistency is important (can correct for consistently high or low values, but can"t correct for inconsistencies) Performance rating should be done only during the observation of elemental times (once recorded, no values should be changed) Frequency of rating depends on cycle times: what procedural steps should a company take in order to train ies in the westinghouse rating. Synthetic rating: system of performance rating where elemental observed times are compared to times developed through predetermine time systems. More than one element should be used because research proves that operator performance varies significantly from element to element, especially in complex work. Weakness: lots of time required to develop the predetermined time system for analysis of the given job: understand the statistical computations for the examples shown for rating analysis and rating.
