In the preceding problem, a recommendation has been submitted for elements d and e to be performed as internal elements (accomplished simultaneously) with machine element b. The worker would file the part from the previous cycle and deposit it in the container while the current part is being processed in the machine automatic cycle. All worker elements were performance rated at 80%. The PFD allowance is 16%, and the machine allowance = 20%.

Determine (a) the normal time for the cycle, (b) the standard time per part. (c) If the workers efficiency is 115% and he works a total of 7 hours and 12 min during an 8-hour shift, how many parts will be produced?

	Element	Description	Cumulative observed time (min)
	a	Worker loads machine and starts automatic cycle.	0.25
	b	Machine automatic cycle	1.50
	c	Worker unloads machine.	1.75
	d	Worker files part to size.	2.30
	e	Worker deposits part in container.	2.40
