Analytics Exercise 4-4 (Algo) 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 olready 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 sctiedule on his desk tomorrow moraing! You have been given the information in Exribit 4.13. it includes all the activities required in the project and the duration of each activity. Also, dependencies between the activities thave been identified. Remember that the preceong actifity must be fully completed before work on the following activity can be startedi Your project is divided into five major subprojects. Subproject " p " involves developing specitications for the new cell phone. Here. decisions related to such things as battery life, size of the phone, and feotures need to be mode. These detalis are besed on how a customer uses the cell phone. These user specifications are redefined in terms that have maaning to the subcontractors that will actually make the new cell phone in subproject "5" supplier spectications. These ifrodve engineering detalls for how the product will perfoem. The individual components that make up the product are the focus of subptoject ' D ' Subproject "i" brings all the components together, and a working prototype is built and tested. Finaly, in subproject - V, supplers are selected and contracts are negotated. Exhubit 413. Work Biealdown Structure and Actrites for the Cet Phone Design Project a. Determine the minimum number of weeks for completing the project. b. Your boss would like you to study the impoct of making two changes to how the project is organized. The first change involves using dedicated teams that would work strictly in paraliel 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 paralel. In other words, there would be no precedence relationships within a subproject-all tasks within a subproject would be worked on at the snme time and each wotid take the same amount of time as originally specifled 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
