INSY 3021 Auburn University Spring 2008 Performance Rating

Normal Performance Benchmarks 0.38 min for walking 100 ft, details should state terrain, load, clothing, etc.. The more clear-cut and specific the definition, the better.

Rating Characteristics Accuracy (paramount), should not deviate by more than 5% from other trials Consistency, Rating higher or lower every time is easier to correct than fluctuations Desirable systems are: Simple, concise, and easy to explain

Rating Types For short element time/cycle times (15-30 sec), it may be more practical to rate the entire study rather than individual elements (TP) For longer elements/cycles (over 30 sec), individual ratings maybe necessary (TP)

Rating Methods Westinghouse System Synthetic Rating Speed Rating Objective Rating

The Westinghouse System Evaluates performance with respects to: Skill, effort, conditions, and consistency

Skill “Proficiency at following a given method.” Proper coordination of mind and hands Six skill degrees/classes: Poor, fair, average, good, excellent, and super + 15 to – 22 range

Effort “Demonstration of the will to work effectively.” Stopwatch Six effort classes: Poor, fair, average, good, excellent, and excessive + 13 to – 17 range

Conditions Present conditions with respect to normal conditions Temperature, ventilation, light, noise, etc… Six condition classes: Poor, fair, average, good, excellent, and ideal + 06 to – 07 range

Consistency Elemental times that continually repeat would be consistent Six consistency classes: Poor, fair, average, good, excellent, and perfect + 04 to – 04 range

Overall Performance Algebraically sum the four individual factors Add this to one Courses available to train analysts, with approximately 25 hours spent watching videotapes to develop the needed skill

Synthetic Rating Determines a performance factor for elements of the cycle by comparing actual elemental observed times to those developed by analyzing fundamental motion data, such as MTM or MOST

Speed Rating Only considers the rate of accomplishment of the work per unit time First determine if the performance is above or below normal Quantify the difference between the actual output and that expected by a “NORMAL OPERATOR” Can be tied to benchmarks such as walking, dealing cards, VO 2

Objective Rating Establishes a single work assignment, against which the pace of all others are measured A second factor relates its relative difficulty Influences are: Amount of body used, foot pedals, bimanualness, eye-hand coordination, handling or sensory requirements, and load Multiply the two factors together

Rating Training & Maintenance Provide initial, refresher, and continuing training to all assigned analysts Record all ratings in analysts file, with the deviations from other analysts Periodically validate their skill level
