(Enter your resp rounded up to the next whole number.) c. Using the longest work element rule, which work elements are assigned to each workstation? Work elements A, H, I should be assigned to Station 1. Work element(s) B should be assigned to Station 2. Work elements GC should be assigned to Station 3. Work elements D, E, J should be assigned to Station 4. Work element(s) F, K should be assigned to Station 5. d. What are the resulting efficiency and balance delay percentages? (Enter your responses as percents rounded to one decimal place.) The efficiency is %. The balance delay is %
