pre divided into frem Case Study: Cell Phone Design Project You work for Motorola in their global cell phone group. You have been made project manager for the design of a new cell phone model. 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 and project costs. Your boss wants the schedule and costs on his desk tomorrow morning! You have been given the information in Exhibit 1. 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 full completed before work on the following activity can be started. Exhibit 1.

Task "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 determined. 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 Task "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 Task "D". Task "T" brings all the e.centennialcollege.ca Case Cell Phone Design Project - 20W --Project Management Principles (SEC.004) ur project is divided into five mejor tasks Task involves developing specification for the components together and a working prototype is built and tested. Finally in Task "V", vendors are selected and contracts are negotiated. 1. Draw a project network that includes all the activities. 2. Calculate the start and finish times for each activity and determine how many weeks is the minimum for completing the project. Find the critical set of activities for the project. 3. Identify slack in the activities not on the project critical path. 4. Your boss would like you to suggest changes that could be made to the project that would significantly shorten it.
