PROJECT QUALITY MANAGEMENT Flashcards
Control charts are one of the seven basic quality tools. They are used as a quality assurance tool in a project and can be used to demonstrate how a process behaves over time, relative to the number of data points above or below the central line. Which of the following statements about a control chart is true?
a. The upper control limit is typically set at +/- 1 sigma
b. Seven consecutive points above or below the central line indicates a process is out of control
c. Seven consecutive points above or below the central line indicates a process is in of control
d. The lower control limit is typically set at +/- 4 sigma
B
The best answer choice is B. Seven consecutive data points above or below the central line indicates a process is out of control.
Which process translates the quality management plan into executable quality activities that incorporate the organization’s quality policies into the project?
a. Plan Quality Management
b. Manage Quality
c. Control Quality
d. Administer Quality
B
The benefits of the Manage Quality process are that it increases the probability of meeting the quality objectives as well as identifying ineffective processes and causes of poor quality.
A structured, independent process used to determine whether project activities comply with organizational
and project policies, processes, and procedures is called:
a. A quality audit
b. A performance review
c. A quality assurance review
d. Procedures conformance examination
A
A quality audit is usually conducted by a team external to the project, such as the organization’s internal audit department or a PMO, or by an auditor external to the organization.
Which of the following is defined as the process of monitoring and recording results of executing the quality activities to assess performance and recommend necessary changes?
a. Earned Value management
b. Cost of Quality
c. Prevention over inspection
d. Control Quality
D
The best answer choice is D because it is the process defined in the question.

helping to identify the main or root cause of the problem. The cause-and-effect diagrams are also known as fishbone diagrams, why-why diagrams, or _____________.
a. Ishikawa diagrams
b. Matrix diagrams
c. Scatter diagrams
d. Histograms
A
An Ishikawa diagram is a cause-and-effect diagram that is also known as a fishbone diagram (because when drawn it looks like a fish).
Steven is managing a small construction project involving an affordable senior health-care facility. He is having some issues and needs to determine the root cause. Which of the following tools and techniques can Steven use to help in find the root cause of the problem?
a. Ishikawa diagram
b. Scatter chart
c. Bar chart
d. Design of Experiments
A
The best answer choice is A. The Ishikawa diagram, also known as the fishbone diagram, is a tool commonly used to determine root cause.
You are conducting the Plan Quality Management process. You have done this previously on other projects, but they involved a different type of product than the one in your current project. From the following choices, select the one that is true regarding the Plan Quality Management process.
a. Quality and customer satisfaction are the same thing
b. Project quality management processes don’t change with product type.
c. You need to coordinate with product quality management
d. The project sponsor should be consulted during this process
B
The best answer choice is B because project quality management processes remain the same in all projects, no matter what the product of the project is.
You’ve outlined a specific process on an assembly line that you manage. You want to make sure that all the
workers follow this new process, and that they make sure that no step is missed. To ensure this happens, what should you create?
a. A Quality Management plan
b. A process improvement plan
c. A checklist
d. Metric matrix
C
A checklist facilitates following the same steps each time a process is executed.
Roy is managing a project with very high standards on the manufacturing processes involved to create the
product. The product is a new hover board that contains an anti-gravity device filled with a new isotope that allows it to levitate the board. This isotope must be kept at a temperature below 23 degrees Celsius during the process in which the outer electron is removed from its orbit. Temperature is critical in this procedure, and Roy needs to make certain there are systems in place to maintain the requirements necessary for the production process. If the system is not closely monitored, defective parts may be created, which could result in rework or excessive scrap, and would add to the project’s cost. In addition, there may be associated warranty work or lost business. In either of these cases, the cause of this result would be which of the following?
a. Cost of conformance
b. Control limits
c. Cost of nonconformance
d. Design of Experiments
C
The best answer choice is C. This scenario describes the cost of nonconformance, which may result in rework, scrap, liabilities, warranty work, or lost business revenue.
Amanda is managing a new project involving the analysis of a new manufacturing process that is designed to reduce defects and speed up the production of the product components. She has been examining the control charts on this new process and has noticed several situations in which seven or more data points are falling above or below the mean. What does this indicate?
a. The upper control limit is too low
b. The process is in control
c. The process is out of control
d. The lower control limit is too high
C
The best answer choice is C. Seven consecutive data points above or below the mean indicate a process that is out of control.
John is managing a new project that is producing injection molded parts with very tight tolerances. This
molding system has been designed using a new process that is currently in the testing phase. John is
examining his control chart to determine whether this new process is in control. John is pleased to see that all of his data points on the chart are falling between the UCL and the LCL. John assumes the process is in control. Is he correct in this assumption?
a. His assumption is correct because all data points are within +/– 3 sigma from the mean
b. His assumption is false, because all data points must fall within +/– 1 sigma of the mean
c. His assumption is correct unless there are seven consecutive data points above or below the
mean
d. His assumption is false unless there are seven consecutive data points above or below the
mean
C
The best answer choice is C. Because all of the data points are falling between the upper and lower control limits, the process is producing the product according to the specifications. However, in order to determine whether the process is in control, John needs to see if there are at least seven consecutive data points falling above or below the mean, not the control limits.
Of the following choices, which one is not an input to the Control Quality process?
a. Statistical sampling
b. Quality metrics
c. Approved change requests
d. Organizational process assets
A
The best answer choice is A because statistical sampling is a tool and technique of this process.
Joshua is managing a project involving critical electrical components that will be used in a GPS instrument for commercial aircraft. The control charts show a minor deviation and a trend of points above the UCL, resulting in an excessive amount of defects and additional costs in labor and material. In order to bring the future project performance in line with the project management plan, which of the following should be Joshua’s first step?
a. Define a corrective action
b. Define a preventive action
c. Initiate a change request
d. Request a change control board meeting
A
The best answer choice is A. A corrective action realigns the project performance with the project management plan and the requirements and is done prior to having a change control board meeting or initiating a change request.
Wanda is reviewing the quality requirements and the quality control measurement results she has just received in order to determine whether the project team is using the appropriate quality standards. In which of the following processes is Wanda involved?
a. Manage Quality
b. Plan Quality Management
c. Control Quality
d. Validate Scope
A
The best answer choice is A because the Manage Quality process is designed to ensure the use of
appropriate quality tools and standards during the project execution.
What are the two aspects of quality management?
a. Project quality and product quality
b. Product quality and process quality
c. Project quality and product satisfaction
d. Process improvement and product satisfaction
A
There are two aspects of quality management—project quality and product quality. Project quality has to do with how you manage the project. Product quality is dependent on the nature of the product.
