Question 7

Consider a shirt-stitching process. The raw material for a shirt arrives as two sheets. One sheet (the front) goes to worker A who takes 5 minutes to process it. The other sheet (the back) goes to worker B who takes 10 minutes to process it. So A and B are done simultaneously, not sequentially. Once both front and back are ready, they go to worker C who stitches them together (4 minutes), then to D (Ironing, 12 minutes) and to E (packing, 5 minutes). All steps (A, B, C, D, and E) are necessary to create each finished unit. Each step employs a single worker. The cycle time achieved by this process is:

15 minutes

12 minutes

5 minutes

10 minutes
