Your project is divided into five major subprojects. Subproject "P" involves developing specifications for the new cell phone. Here, decisions related to such things as battery life, size of the phone, and features need to be made. These details are based on how a customer uses the cell phone. These user specifications are redefined in terms that have meaning to the subcontractors that will actually make the new cell phone in subproject " S " supplier specifications. These involve engineering details for how the product will perform. The indlvidual components that make up the product are the focus of subproject "D." Subproject " I " brings all the components together, and a working prototype is built and tested. Finally, in subproject "V," suppliers are selected and contracts are negotiated. a. Determine the minimum number of weeks for completing the project. b. Your boss would like you to study the impact of making two changes to how the project is organized. The first change involves using dedicated teams that would work strictly in parallel on the activities in each subproject. For example, in subproject P (product specifications) the team would work on P1, P2, P3, and P4 all in parallel. In other words, there would be no precedence relationships within a subproject-all tasks within a subproject would be worked on at the same time and each would take the same amount of time as originally specified. With this new design, all the subprojects would be done sequentially with P done first, then S,D,I, and finally V. The second change your boss would like you to consider would be to select the suppliers during subproject P and have them work directly with the dedicated teams as described in the first change. This would involve adding an additional activity to subproject P called supplier selection and contract negotiation (P5) with a duration of 12 weeks. This new activity would be done in parallel with P1, P2, P3, and P4. Subprojects S and V would be eliminated from the project. What would be the expected impact on how long it would take to complete the project if this additional change were made
