An analyst has timed a metal cutting operation for 60 bikes. The average time per cycle was 10.30 minutes, and the standard deviation was 1:20 minutes for a worker with a performance rating of 120 percent. Assume an allowance of 16 percent of job time. Find the standard time for this operation.

Susan Cottenden clocked the observed time for weld-ing a part onto truck doors at 5.3 minutes. The performance rat-ing of the worker timed was estimated at 105%. Find the normal
time for this operation.Note: According to the local union contract, each welder isallowed 3 minutes of personal time per hour and 2 minutes offatigue time per hour. Further, there should be an average delayallowance of 1 minute per hour. Compute the allowance factorand then find the standard time for the welding activity.

The analyst feels the worker was performing their task, on average, about 25% faster than normal. What would be the resulting standard time assuming a 20% allowance for fatigue and personal needs?arrow_forwardA worker-machine operation was found to involve 3.3 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. The worker’s time averaged 1.9 minutes per cycle, and the worker was given a rating of 120 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break.
