1.Consider a project consisting of multiple activities. You were told that a ceratin activity known as activity "M" had a normal time of 11 weeks and a crashed time of 9 weeks, but actually took 13 weeks to complete. What is the corresponding expected impact on the project schedule?

A.Unknown- not enough information

B.Project will be delayed by 2 weeks

C.Project will be delay by 4 weeks

D.No impact

2.Which of the following statements about the critical path and critical chain methods of project scheduling is False?

A.the critical chain can be shorter than the critical path

B.the critical chain includes resource constraints

C.the critical path assumes unlimited resources

D.the critical chain can be longer than the critical path

E.None- all of the above statements are true

3.

Basic CPM/PERT methods ignore resource constraints when scheduling project activities. In many projects, however, resource constraints, conflicts and overloads can be real obstacles to project completion. Which of the following approaches is not an approach for the project manager to resolve difficulties due to resource constraints? Delay the project completion date Obtain more resources Move the start time of critical activities Move the start time of activities with slack
