PMI-001 Q&A – Section 4: Time Management (141-150)

Section 4: Time Management

To control the schedule, a project manager is reanalyzing the project to predict project duration. She does this by analyzing the sequence of activities with the least amount of scheduling flexibility. What technique is she using?
A. Critical path method
B. Flowchart
C. Precedence diagramming
D. Work breakdown structure
Answer: A

There are only two choices related to scheduling: A and C. Choice C, however, is a diagramming technique that deals with the relationship between activities, not schedule flexibility.

Management wants the project completed in 40 days. The cost performance index (CPI) is 1.1, the project critical path duration is 38 days with a standard deviation of two days. What is the maximum project float?
A. Zero days
B. Two days
C. Four days
D. One day
Answer: C
Standard deviation is a range that an estimate can vary +/- from the mean. The project needs to be done in 40 days, and the schedule calls for 38 days, so the project float is 2 days. With a standard deviation of two days, the project will take 38 +/- 2 days, or 36 to 40 days. Therefore, project float could be 0 to 4 days.

A project has experienced significant delays due to equipment problems, staff attrition, and slow client reviews. The project is 40 percent complete and has used 60 percent of the available calendar time. What is the FIRST thing you should do?
A. Rebaseline the schedule to reflect the new date.
B. Analyze the critical path activities for potential to fast track or crash the schedule.
C. Document the lack of progress and associated issues to management.
D. Identify activities that required more time than planned.
Answer: D
Rebaselining (choice A) hides performance problems rather than managing issues as they occur. Choice C may need to be done, but it is not proactive. Choice B is not a bad choice, but it cannot be done without knowing why there was a delay. Imagine that a resource’s skills are not what you have been led to believe, and that resource is working on another activity later in the project. If you crash or fast track activities involving that resource, the problem could recur. Identifying the root causes of the delay (choice D) will help determine what to do about them.

Senior management is complaining that they are not able to easily determine the status of ongoing projects in the organization. Which of the following types of reports would help provide summary information to senior management?
A. Detailed cost estimates
B. Project management plans
C. Bar charts
D. Milestone reports
Answer: D
Detailed estimates (choice A) have nothing to do with the situation described. Project management plans (choice B) will have more detail than is necessary for the situation described and may distract from the conversation if used in this situation. Bar charts (choice C) are usually only for the team. The best answer is choice D because milestone reports present the right level of detail for upper management.

You are a project manager for a small construction project. Your project was budgeted for US $72,000 over a six-week period. As of today, you have spent US $22,000. The earned value is US $24,000.

A. Ahead of schedule.
B. Behind schedule.
C. On schedule.
D. Having not enough information provided.
Answer: B
SPI = EV/PV. In this case SPI = 24,000/30,000, or 0.8. An SPI of 0.8 indicates that you are behind schedule.
