The snapback timing method was used to obtain the average times and performance rat- ings 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 is applied to the cycle. Determine (a) the normal time and (b) the standard time for this cycle. If the workers 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 and (d) what is the workers efficiency?

Work element Observed time (min) a0.32b0.85c0.48d0.55e1.50
