Question: Refer to the Package Sorting case in. Budworth, Heimbuch, and Kennedy were told that the sorting system was set up to let a package circle on the conveyor belt for 10 cycles (once each cycle the package would fall into the correct chute if that chute was not occupied). If after ten cycles the correct chute was always occupied, a package would be consigned to the inefficient "no chute open" bin. Upon observing the system in operation, the team immediately recognized packages dropping into the "no chute open" bin after only 2 or 3 cycles. Management was notified and the programming of the system was corrected. The team gathered the data below after the correction.
(a) Extend the control limits from your chart in part (e) of. Plot the data above on the same chart. Does it appear the system change was effective? Why or why not?
(b) Make a chart to assess stability of the number of packages in the "no chute open" bin using only the data above. Does it appear the system was stable? Why or why not?
(c) Has the team solved the problem of a large number of packages in the "no chute open" bin? Defend your answer.
