Please answer question #4 down below using 5.13 and provide an explanation of the answer and the process of getting the answer! thank you! will thumbs up!!

4. You have been asked 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 subprojectall 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. What would be the expected impact on how long it would take to complete the project if this change were made?

ANALYTICS EXERCISE: PRODUCT DESIGN PROJECT You work for a company that makes cell phones and have as battery life, size of the phone, and features need to be been made project manager for the design of a new cell made. These details are based on how a customer uses the phone. Your supervisors have already scoped the project, so cell phone. These user specifications are redefined in terms you have a list showing the work breakdown structure, and that have meaning to the subcontractors that will actually this includes major project activities.
