VI 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 You have been given the information in Table-I below. 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 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 howa 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 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, You have been asked to study the impact of making two changes as 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 in Table 1. 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 to consider would be to select the suppliers during subproject and have them work directly with the dedicated teams as described in step 4. This would involve adding an additional activity to subproject P called Supplier Selection and Contract Negotiations (P5) with a duration of 12 wocks. This new activity would be done in parallel with PI, P2, P3, and P4. Subproject S and V would be eliminated from the project. With this new design, all the subprojects would be done sequentially with P done first, then D, and finally I. h) Druw a project network that includes all the activities with times. (10 points) i) Calculate the early and late times for each activity. List those in a table. (10 points) What would be the expected impact on how long it would take to complete the project if this change were made? (10 points)
