Please answer part A and B for question 3.

You work for a company that makes cell phones and have been made project manager for the design of a new cell phone. Your supervisors have already scoped the project, so you have a list showing the work breakdown structure, and this includes major project activities. You must plan the project schedule and calculate project duration Your boss wants the schedule tomorrow morning! You have been given the information in Exhiba 413 . It includes all the activities required in the project and the duration of each activity. Also, dependencies between the activities have been identified. Remember that the preceding activity must be fully completed before work on the following activity can be started 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 individual components that make up the product are the focus of subproject " D " Subproject " % " 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. You have been asked 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. What would be the expected impact on how long it would take to complete the project if this change were made
