Question 8. Suppose you created your activity network and discovered that you had two critical paths in your project. You share this information with another project manager, who strongly argues that a project can have only one critical path; therefore, your calculations are incorrect. What is the correct response to his assertion?
a) A project can have more than one critical path, although having multiple critical paths is also likely to increase the risk of the project falling behind.
b) Your coworker is correct; a project can have only one path. You need to return to the network and determine where you erred in developing the network logic and diagram
c) The critical path is the shortest path through the network, so more than one is not a significant problem.
d) A project can have more than one critical path, although having multiple critical paths is actually likely to decrease the risk of the project.

Question 9. Todd is working on resource scheduling in preparation for the start of a project. There is a potential problem in the works, however, as the new collective bargaining agreement with the company’s union has not been concluded. Todd decides to continue working on the resource schedule in anticipation of a satisfactory settlement. Todd’s approach would be an example of which method for dealing with risk?
a) Accept it
b) Minimize it
c) Transfer it
d) Share it
Question 10. Suppose your organisation used a qualitative risk assessment matrix with three levels each of probability and consequences (high, medium, and low). In evaluating a project’s risks, you determine the commercial risks pose a low probability of occurrence but high consequences. On the other hand, legal risks are evaluated as having a high probability of occurrence and medium consequences. If you are interested in prioritising your risks, which of these should be considered first?
a) Commercial risks
b) Legal risks
c) Both should be considered equally significant
d) Neither is much of a threat to this project, so it doesn’t matter what order you assign them
Question 11. One common mistake made early in the risk identification process is to
a) Consider limited possibilities
b) Encourage participants to be over-optimistic
c) Support participants being over pessimistic
d) Focus on consequences and not on the events that could produce consequences
e) Give too much attention to past events
