QUESTION: 25

John works as a project manager of the NHQ Project. He has created the project network diagram as shown in the figure:

Based on the project network diagram, how much float is available for Activity H if Activity B is delayed by four days and Activity E is delayed by two days?

Zero
One
Four
Five

Answer(s): A

Explanation:

The path of ABEHJ will take 22 days to complete and cannot exceed 28 days or else the project will be late. If Activity B takes four additional days and Activity E takes two additional days, this adds (4+2= 6) six days to the path, bringing the path's duration to exactly (22+6 = 28) days. There is no available float left for Activity D or H. Float or total float (TF) is the total amount of time that a schedule activity may be delayed from its early start date without delaying the project fish date, or violating a schedule constraint. It is calculated by using the critical path method technique and determining the difference between the early finish dates and late finish dates. Answer options B, C, and D are incorrect. There is no float available because the path's duration has increased to 28 days.

QUESTION: 26

Ben is the project manager for his organization. His project has 26 stakeholders this week and will have five additional stakeholders next week. How many more communication channels will Ben's project have next week?

Answer(s): A

Explanation:

Ben's project will have 140 more communication channels because of the five additional stakeholders. To solve the question, you will need to find the current stakeholder communication channels first, which is (26*25)/2= 325, and then find the difference of the number of channels for the five additional stakeholders. You can use the formula of N(N-1), where N is the number of stakeholders. In this example, the formula would read: Total number of communication channels that Ben will have next = ((31*30)/2)-((26*25)/2 =140
Answer option D is incorrect. Five is the number of additional stakeholders.
Answer option B is incorrect. 10 is the number of communication channels among just five stakeholders.
Answer option C is incorrect. 325 is the number of current communication channels.

QUESTION: 28

You are the project manager for your organization. You need the oak cabinets for your project delivered by December 1 in order to install the floors around the oak cabinets by December 15. Your company's procurement office generally takes 45 days to complete procurement orders. Based on this information, how should you schedule the lead time for the cabinet delivery?

Cabinet procurement December 1, plus 45 days lead time
Cabinet procurement November 15
Cabinet procurement December 1, minus 45 days lead time
Cabinet procurement December 15 minus 45 days lead time

Answer(s): C

Explanation:

The cabinet procurement and delivery must be completed by December 1. By scheduling the activity to finish on December 1 with minus 45 days lead time for procurement, the cabinets will arrive by the needed date.
Answer option A is incorrect. Lead time is always negative time, lag time is positive time. This choice would cause the cabinets to not arrive until 45 days after December 1.
Answer option D is incorrect. This choice would cause the cabinets to arrive on December 15 when the floors are to be installed.
Answer option B is incorrect. This choice is not the best answer because it does not necessarily account for holidays, weekends, or other factors in the project calendar. By scheduling the cabinet for December 1 and working backwards through lead time, the project's PMIS will account for these breaks in the project work.
