The product structure. J K(1) L(4) M(2) You have developed the following simple product structure of items needed for your gift bag for a rush party for prospective pledges in your organization. You forecast 200 attendees. You are expected to have the gift bags ready at 5 P.M. However, you need to personalize the items (monogrammed pens, note pads, literature from the printer, etc.). The lead time is 1 hour to assemble 200 Js once the other items are prepared. The other items will take a while as well. Given the volunteers you have, the other time estimates are item K (1 hour), item L (2 hours), and item M (3 hours). Develop a time-phased assembly plan to prepare the gift bags.
