Which of the following can be used to determine whether a sample product is within an acceptable range?
Correct Answer: C
A control chart is a graphical tool that displays the variation of a process over time and compares it to predetermined control limits. It can be used to determine whether a sample product is within an acceptable range by checking if the sample values fall within the upper and lower control limits, which indicate the expected variation of the process. If the sample values are outside the control limits or show a non-random pattern, it indicates that the process is out of control and there may be some assignable causes of variation that need to be investigated and corrected.

Question 147
A project manager is eager to define access requirements during the initiation phase of a project. Which of the following steps should the project manager perform first?
Correct Answer: D
This answer is based on the best practice of defining access requirements in project management, which is to identify the roles, responsibilities, and permissions of the project team members and other stakeholders who need to access the project information, resources, and deliverables12. The first step in this process is to assess the resource pool, which is the availability and capability of the human resources that can be assigned to the project34. By assessing the resource pool, the project manager can determine the skills, experience, and security clearance of the potential project team members, as well as their reporting relationships, communication preferences, and expectations56. This information can help the project manager to define the access requirements for each role and stakeholder group, and to assign the appropriate level of access to the project data, documents, tools, and systems78.

Question 148
Which of the following tools should a project manager use to assess the activities performed, work effort applied, and the productivity of a project?
Correct Answer: B
A project evaluation review is a tool that helps a project manager assess the activities performed, work effort applied, and the productivity of a project. It involves collecting and analyzing data on the project's performance, outcomes, and impacts. It also provides feedback and recommendations for improvement and learning. A project evaluation review can be done at different stages of the project life cycle, such as during or after completion.

Question 149
Which of the following provides the best justification for undertaking a project?
Correct Answer: B
A business case provides justification for undertaking a project, programme or portfolio. It evaluates the benefit, cost and risk of alternative options and provides a rationale for the preferred solution. A business case is essential for demonstrating the value of the project and securing the approval and funding from the governance. A business case is different from a scope statement, which defines the project boundaries and deliverables; a sponsor request, which initiates the project idea and seeks support; and a project charter, which authorizes the project and assigns the project manager.

Question 150
During the execution phase of a project, the project team faced an unexpected website downtime The project manager how a brainstorming session and the team identified causes and effects tor the problem Now the project team needs to analyze and determine whether the particular cause and effect are related by using one of the following charts. Which of the following should the team use?
Correct Answer: A
Option A shows a cause and effect diagram, also known as a fishbone diagram or an Ishikawa diagram1. This is a tool that helps to identify and analyze the root causes of a problem by displaying the possible causes and effects in a graphical format2. A cause and effect diagram can help the project team to determine whether the particular cause and effect are related by using a systematic and logical approach, such as asking "why" questions or using the 5 Whys technique34. A cause and effect diagram is better than the other options because: Option B shows a Gantt chart, which is a tool that helps to plan and track the tasks, dependencies, durations, and resources of a project along a timeline5. A Gantt chart does not focus on the causes and effects of a problem, but rather on the sequence and progress of the project activities. Option C shows a pie chart, which is a tool that helps to compare and visualize the proportions of different categories or segments of data6. A pie chart does not show the relationships between the causes and effects of a problem, but rather the distribution of the data values. Option D shows a scatter plot, which is a tool that helps to examine the correlation or association between two variables or sets of data7. A scatter plot does not show the causes and effects of a problem, but rather the pattern or trend of the data points.
