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. What would be the expected impact on how long it would take to complete the project if this change were made? The duration of the project will to weeks
