The snapback timing method was used to obtain the average times and performance ratings for work elements in a manual repetitive task. (See table below). All elements are worker-controlled and were performance rated at 80%. Element e is an irregular element performed every five cycles. A 15% allowance for personal time, fatigue, and delays isapplied to the cycle. Determine (a) the normal time and (b) the standard time for this cycle. If the worker’s performance during actual production is 120% on all manual elements for 7 actual hours worked on an 8-hour shift, (c) how many units will be produced
The results of a time study to perform a quality control test are shown in the following table:
*Disregard employee is smoking a cigarette (included in personal time).
The allowance factor is given to be 25%.
a) The normal time for the complete operation =
b) The standard time for this process =
