Your project is divided into five major subprojects. Subproject “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 made. 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 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.MAJOR SUBPROJECTS/ACTIVITIESACTIVITY IDENTIFICATIONDEPENDENCYDURATION (WEEKS)Product Specifications (P) Market researchP1—6Overall product specificationsP2P14HardwareP3P26SoftwareP4P36Supplier specifications (S) HardwareS1P45SoftwareS2P46Product design (D) BatteryD1S11DisplayD2S16CameraD3S11Outer coverD4D1, D2, D34Product integration (I) HardwareI1D43User interfaceI2D26Software codingI3I26Prototype testingI4I1, I35Subcontracting (V) Suppliers selectionV1S1 ,S210Contract negotiationV2I4, V12 a.
