The snapback timing method was used to obtain average time and performance rating values for the work elements in a certain repetitive task. The values are given in the table below. Elements a, b, cand f are worker-controlled. Element d is a machine-controlled element and their time is the same each cycle (N.A. means performance rating is not applicable). Element c is performed while the machine is performing its cycle (element d). Element e and g are worker-controlled irregular elements performed every five cycles. The machine is idle during elements a, b, and g. Four product units are produced each cycle. The machine allowance is zero, and a 13\% PFD allowance is applied to the manual portion of the cycle. a. Determine the normal time for the cycle. (5 pts.) b. Determine the standard time for the cycle. (5 pts.) If the worker's performance during actual production is 135% on all manual elements for seven actual hours worked on an eight-hour shift. c. How many units will be produced? (4 pts.) d. What is the worker's efficiency? (4 pts.)
