The first change involves using dedicated teams that would work strictly in parallel on the activities in each sub$-$ project For example $,$ in subproject P $($ product speci$-$ fications$)$ the team would work on P$2,$ P$3,$ and P$4$ all in parallel In other words, there would be no pre$-$ cedence 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 be expected impact on how long it would take to com$-$ plete the project if this change were made? The second change to consider would be to select the suppliers during subproject P and have them work directly with the dedicated teams as described in step $4$ This would involve adding an additional activity to subproject P called supplier selection and contract negotiation $($P$5)$ with a duration of $12$ weeksThis new activity would be done in parallel with P$2$ P$3$and P$4$Subprojects S and V would be eliminated from the projectWhat would be the expected impact on how long it would take to complete the project if this additional change were made? Evaluate the impact of making these changes criteria other than just the time to complete the proj Do you think it would be best to try to make these changes in how the runs this and future cell phone
