my numbers have not added up and need clarification

orm Dleted before work on the following activity can be started. ur project is divided into five major subprojects. Subproject *P* involves developing specifications for the new cell phone. Sions related to such things as battery life, size of the phone, and features need to be made. These details are based on hc omer uses the cell phone. These user specifications are redefined in terms that have meaning to the subcontractors that wil ally make the new cell phone in subproject "S" supplier specifications. These involve engineering details for how the produ The individual components that make up the product are the focus of subproject "D" Subproject "I" brings all the component Ether, and a working prototype is built and tested. Finally , in subproject "V" suppliers are selected and contracts are negotiated. ibit 4.13: Work Breakdown Structure and Activities for the Cell Phone Design Project AJOR SUBPROJECTS/ACTIVITIES ACTIVITY IDENTIFICATION DEPENDENCY DURATION (WEEKS) Product Specifications (P) Market research 3 Overall product specifications P1 5 Hardware Software Supplier specifications (5) Hardware 51 Software S2 Product design (D) Battery D1 Display Camera Outer cover Product integration (1) Hardware User interface Software coding Prototype testing Subcontracting (V) Suppliers selection Si S2 Contract negotiation 14, VI P1 P2 P3 P4 P2 P3 4 4 P4 P4 4 7 1 FEE A BES ART IT M 51 S1 S1 D1, D2, D3 1 5 11 12 13 14 04 D2 12 11, 13 4 5 5 11 V2 a. Determine the minimum number of weeks for completing the project Minimum number of weeks b. Your boss would like you 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 subproject. For example, in subproject P (product specifications, the team would work on P1, P2, P3, and P4 all in parallel. In other words, there would be no precedence 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. The second change your boss would like you to select the suppliers during subproject P and have them work directly with the dedicated teams. This would involve adding an additional activity to subproject P called supplier selection and contract negotiation (P5) with a duration of 13 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 these changes were made?
