You are the project manager of the GHQ Project. You are working with your project team to create the project network diagram. You have created the PND and are identifying the critical path with your team using your project management information system. All of the activities on the critical path are showing in red in the software that you are using to evaluate the critical path. What are schedule activities on the critical path called?
Correct Answer:A
Schedule activities on the critical path are called critical activities. Critical activity is a specific schedule activity on the critical path that takes place within a project schedule. Critical activities are mainly determined during the execution and deployment of the critical path method. In project management terms, critical activity refers to being on the major critical path, the most important path of life of an activity. Critical activity can also be defined as the work elements that must be carefully monitored, documented, and managed to make the success of an organization, program, or project. An activity that has a total float equal to zero is believed to be a 'critical activity', which means if an interruption in the finish time of an activity occurs, then the entire project will be delayed by the same amount
of time. A critical activity generally has free float equal to zero.
Answer options D, C, and B are incorrect. These are not valid answers for this question.
In which of the following group decision making techniques does the largest block in a group decide the group decision even if a bulk is not achieved?
Correct Answer:D
The various techniques of group decision making are as follows: Unanimity: In this technique, everyone agrees on a single course of action. Majority: In this technique, more than 50% of the members of the group support the decisions. Plurality: In this technique, the largest block in a group decides even if a bulk is not achieved. Dictatorship: In this technique, one individual makes the decision for the group.
Holly is the project manager of the NDS project and she is 85 percent complete with her project though she should be 95 percent complete. Her project has a BAC of $9,850,400 and she has spent $8,011,221 to date. What is Holly's schedule performance index for this project?
Correct Answer:C
The schedule performance index is found by dividing the earned value by the planned value. For Holly's project, it would be as follows:
SPI = EV/PV
= (0.85*9,850,400)/(0.95*9,850,400)
=8,372,840/9,357,880
=0.89
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 D is incorrect. Ten percent is not a valid calculation for this question. Answer option B is incorrect. 0.98 is the cost performance index.
Answer option A is incorrect. 1.07 is the to-complete performance index based on the BAC.

You work as a Project Manager for Media Perfect Inc. Several projects are running under your supervision. Rick, team leader of a project, provides you performance indexes of his project. The schedule variance (SV) of his project is 25. What does this figure depict?
Correct Answer:D
According to the question, the schedule variance (SV) of the project is 25, which is a positive value. The positive SV depicts that the project is ahead of the planned schedule. What is SV? Schedule variance (SV) is a measure of schedule performance on a project. The variance notifies that the schedule is ahead or behind what was planned for this period in time. The schedule variance is calculated based on the following formula: SV = Earned Value (EV) - Planned Value (PV) If the resulting schedule is negative, it indicates that the project is behind schedule. A value greater than 0 shows that the project is ahead of the planned schedule. A value of 0 indicates that the project is right on target.
Answer option A is incorrect. The negative SV means that project is behind the schedule. Answer option C is incorrect. The zero SV means that project is right on target.
Answer option B is incorrect. This result can be drawn by looking at the cost variance (CV) of the project. What is CV? Cost variance (CV) is a measure of cost performance on a project. The variance notifies if costs are higher than budgeted or lower than budgeted. The cost variance is calculated based on the following formula: CV = Earned Value (EV) - Actual Cost (AC) A positive value means that spending is less than budgeted, whereas a negative value indicates that costs are higher than originally planned for the project.
