You work as the project manager for Blue Well Inc. You are working with your project team to schedule the days the project work will take place. You have created a project network diagram as shown in the figure:

Based on this diagram, find out the earliest day on which Activity G can be started.

Correct Answer:D
The earliest Activity G can start is Day 17. This is because activities A, D, C, and F must all be completed before Activity G can start.
Answer option A is incorrect. Day 13 does not account for Activity F since Activity F is also a predecessor to Activity G.
Answer option C is incorrect. Day 22 is the earliest Activity G can finish. Answer option B is incorrect. Day 7 is not a valid answer.

You are the project manager of the NGG Project. This project will be using a new material that the project team has never worked with before. You'd like to use some preventive action to ensure that the installation of the new materials is successful in the project. Which one of the following project actions is an example of the best preventive action for this project?

Correct Answer:A
In order to ensure that the installation of the new materials is successful in the project, you should hire a subject matter expert to train the project team how to install the materials. This is the best preventive action that you can take in case the project team has never worked on the material.
Answer option C is incorrect as while this approach may work it's not the best corrective action as the project team isn't learning how to use the new materials.
Answer option B is incorrect as this approach practically encourages the team to waste materials without training them how to install the materials properly.
Answer option D is incorrect as the incentive program is flawed if the team doesn't understand how to install the new materials to begin with.

Beth is the project manager for the NHQ project. This project deals with fiber optic cabling in her organizational campus. Tim is the electrical engineer for her company and is the only
internal resource that can complete several of the project activities that deal with the fiber optic cables. Because Tim is a highly-skilled resource, he is already scheduled on several projects within the organization and is not available when Beth needs him to complete some of the project activities. This is an example of which term?

Correct Answer:D
Because the activities in Beth's project require Tim and his skills. This is an example of an activity resource requirement. A resource constraint would also have been an acceptable answer.
Answer option B is incorrect. This may be a matrix organization, but matrix network is not a valid project management term.
Answer option C is incorrect. Organizational process assets are things that have been created to help assist the management of the project.
Answer option A is incorrect. A resource calendar conflict is not a valid project management term.

You are the project manager of the NHQ Project. This project has a Budget at Completion of $750,000 and is expected to take 18 months to complete. The project is supposed to be 75 percent complete, but due to some errors the project is only 60 percent complete. At this time the project has spent $465,500. Management has asked you to review the project work and report the project's SPI. What is the SPI for this project?

Correct Answer:B
The project's schedule performance index (SPI) can be found by using the formula; earned value/planned value. The earned value is the percent of the project completed times the BAC. The planned value is the percentage of where the project should be times the budget at completion. In this instance, the formula reads: $450,000/562500 = 0.80. Schedule performance index (SPI) is the measure of schedule efficiency on a project. It is used in trend analysis to predict future performance. SPI is the ratio of earned value to planned value. The SPI is calculated based on the following formula: SPI = Earned Value (EV) / Planned Value (PV) If the SPI value is greater than 1, it indicates better than expected performance, whereas if the value is less than 1, it shows poor performance. The SPI value of 1 indicates that the project is right on target.
Answer option A is incorrect. This value is the project's Cost Performance Index (CPI). Answer option D is incorrect. This value is the schedule variance for the project. Answer option C is incorrect. $562,500 is the planned value for the project.

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?

Correct Answer:A
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.

You are the project manager of the NHQ Project. You have 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 D is delayed by two days?

Correct Answer:D
The path of ABDHJ will take 21 days to complete and cannot exceed 27 days or else the project will be late. If Activity B takes four additional days and Activity D takes two additional days, this adds (4+2= 6) six days to the path, bringing the path's duration to exactly (21+6 = 27) twenty seven days. There is no available float left for Activity E 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 finish 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 A, C, and B are incorrect. There is no float available because the path's duration has increased to 27 days.
