20 Question 10 Activity A has a duration of 3 days and begins on the morning of Monday the 4th. The successor activity, B, has a finish-to-start relationship with A. The finish-to-start relationship has 3 days of lag, and activity B has a duration of 4 days. Sunday is a non workday. What can be determined from these dates? a. The total duration of both activities is 7 days b. Calendar time between start of A to the finish of B is 11 days c. The finish date of B is Wednesday the 13 th d. a and b e. a, b, and c 20

21 Question 10 - Answer Activity A has a duration of 3 days and begins on the morning of Monday the 4th. The successor activity, B, has a finish-to-start relationship with A. The finish-to-start relationship has 3 days of lag, and activity B has a duration of 4 days. Sunday is a non workday. What can be determined from these dates? a. The total duration of both activities is 7 days b. Calendar time between start of A to the finish of B is 11 days c. The finish date of B is Wednesday the 13 th d. a and b e. a, b, and c 21

22 Question 10 - Answer a and b The duration of A, which is 3, is added to the duration of B, which is 4, for a total of 7. The 3 days between the activities is lag and not duration. The lag is a constraint and must be taken into account as part of the network calculations, but it does not consume resources. The total time by the calendar is 11 days as counted from the morning of Monday the 4th. The lag occurs over Thursday, Friday, and Saturday. Sunday is a non working day, so activity B does not start until Monday the 11th. Therefore, the calendar time is 11 days and activity B ends on Thursday the 14th. 22

39 Question 18 - Answer Each of the following Statements about risk avoidance is true except that it - a. Focuses on eliminating the elements that are creating the risk b. Includes making the decision not to bid a project in which the risk exposure is believed to be too high c. Accepts the consequences of the risk event should it occur d. Includes adopting an alternative, lower-risk technology path e. Includes leaving the risk with the customer when the customer is in the best position to mitigate the risk Accepting the consequences of the risk event is categorized as risk acceptance. With this response development approach, the project team takes no action to reduce the probability of the risk's occurring. 39

40 Question 19 In a proactive approach to project risk management, the amount of a contingency reserve should be based on a. Standard allowance b. Percentages based on past experience c. The sum total of the most likely probability and impact of the various risk items d. A set amount allocated to each item proportionately e.

41 Question 19 - Answer In a proactive approach to project risk management, the amount of a contingency reserve should be based on a. Standard allowance b. Percentages based on past experience c. The sum total of the most likely probability and impact of the various risk items d. A set amount allocated to each item proportionately e. An allowance of 10% for each phase in the project life cycle After appropriate allowances have been determined, allocations should be made to the major functional areas of responsibility. With the other approaches, the funds are often depleted before the end of the project because of the temptation for others to use the reserve fund for purposes other than risk management. 41

42 Question 20 Risk mitigation involves a. Using performance and payment bonds b. Eliminating a specific threat by eliminating the cause c. Avoiding the schedule risk inherent in the project d. Assigning the risk to a subcontractor e. Reducing the expected monetary value of a risk event by reducing the probability of occurrence 42
