Task 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 ser 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 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.
