please answer all components of the one problem posted

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 proje activities. You must plan the project schedule and calculate project duration Your boss wants the schedule on his desk tomorrow moming! You have been given the information in Exhibit 5.13. It includes all the activities required in the project and the duration of each activitu 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 Pinvolves 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 controces are negotiated Exhibit 5.13: Work Breakdown Structure and Activities for the Cell Phone Design Project MAJOR SUBPROJECTS/ACTIVITIES ACTIVITY IDENTIFICATION Product Specifications (P) DEPENDENCY DURATION (WEEKS) Market research P1 1 Overall product specifications P2 3 Hardware P3 Software P4 4 Supplier specifications (5) Hardware S1 P4 Software 52 P4 Product design (0) Battery D1 SI 1 Display D2 1 Camera 03 1 Outer cover 04 D1, D2, D3 Product integration (I) Hardware 11 3 User interface 12 3 Software coding 13 I2 3 Prototype testing 14 11, 13 3 Subcontracting (V) Suppliers selection VI 51,52 9 Contract negotiation V2 14, Vi 1 Lada 22 na 88 3 a.
