Your supervisors have already scoped the projects you have a list showing the work breakdown structure this includes major project activities. You must plan the pool ect schedule and calculate project duration Your bou want the schedule on his desktomorrow morning! You have been given the information in Echibi 5.13 It includes all the activities required in the project and the duration of each activity. Abe, dependencies between the activities have been identified. Remember that the preceding activity must be fully completed before work on the follow ing 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 battery life, sire of the phone, and features need to be made. These details are based on how a customer uses the thu have meaning to the subcontractors that will actually make the new cell phone in subproject supplier speci fication. These involve engineering details for how the The individual components that make up the product are the focus of subproject D. Subproject I brings all the compo- nents together, and a working prototype is built and tested. Finally, in subproject Vsuppliers are selected and con- product will perform tracts are negotiated 1.

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 sub- project. For example, in subproject P (product speci- fications) the team would work on P1, P2, P3, and P4 all in parallel. In other words, there would be no pre- cedence 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 165 PROJECTS chapter 5 cal path completing the project.

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 cach sub project. For example, in subproject P (product speci- fications) the team would work on P1, P2, P3, and P4 all in parallel.

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 com- plete the project if this change were made? 5. The second change to consider would be to select the suppliers during subproject P 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 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? 6. Evaluate the impact of making these changes using criteria other than just the time to complete the proj- ect. Do you think it would be best to try to make these changes in how the firm runs this and future cell phone design projects? PRACTICE EXAM
