Critical Path: P1-P3-S2-D5-D7-D1-I1-I3-V2
Question3:
Shortening the duration of the project
As the duration of the project is directly dependent on the duration of critical path, we should make the critical path shorter; in this case we need to re-plan the project.
Manager should shorten the duration or work on a task on the critical path, this can have a significant impact on the overall duration of the project, or they should change a task constraint to allow for more scheduling flexibility.
We have a number of options and we should assess the impact of each on
