PMBOK Project Quality Management 2 — Questions and Answers
Question 1: According to PMBOK, quality is best defined as the degree to which:
- A project meets its schedule and budget targets
- A set of inherent characteristics fulfills requirements (Correct answer)
- Deliverables exceed customer expectations consistently
- The project team follows established processes and standards
Correct answer: A set of inherent characteristics fulfills requirements
PMBOK defines quality as 'the degree to which a set of inherent characteristics fulfills requirements,' focusing on meeting stated and implied needs.
Question 2: A quality audit in PMBOK is best described as:
- A financial review of all quality-related project expenditures
- A structured review to identify inefficient processes and non-compliant activities (Correct answer)
- A customer inspection of final deliverables before acceptance
- A comparison of the project quality against industry benchmarks
Correct answer: A structured review to identify inefficient processes and non-compliant activities
A quality audit is a structured, independent review designed to determine if project activities comply with organizational and project policies and procedures.
Question 3: What is the primary purpose of quality metrics in project management?
- To define the quality budget allocation for the project
- To provide specific measurable criteria used in the Control Quality process (Correct answer)
- To identify stakeholder quality expectations and preferences
- To compare quality costs between current and past projects
Correct answer: To provide specific measurable criteria used in the Control Quality process
Quality metrics define specific attributes of a product or process and how they will be measured, providing the criteria used in the Control Quality process.
Question 4: Which quality management tool graphically displays the relationship between an effect and its possible causes?
- Control chart
- Pareto diagram
- Scatter diagram
- Cause-and-effect diagram (Correct answer)
Correct answer: Cause-and-effect diagram
A cause-and-effect diagram (also called fishbone or Ishikawa diagram) graphically displays the relationship between an effect and its potential causes.
Question 5: Statistical sampling in quality control refers to which of the following practices?
- Collecting data from every unit produced in the project
- Selecting a portion of a population for inspection instead of testing 100% (Correct answer)
- Using statistical software to analyze all project performance data
- Applying standard deviations to calculate schedule variance
Correct answer: Selecting a portion of a population for inspection instead of testing 100%
Statistical sampling involves inspecting a representative part of the population, which reduces costs when 100% inspection is impractical or too expensive.
Question 6: Which statement best describes the relationship between quality and grade in PMBOK?
- Quality and grade are interchangeable terms in project management
- Low quality is always a problem; low grade may not be a problem (Correct answer)
- High grade always ensures high quality in project deliverables
- Grade and quality both refer to the level of features in a product
Correct answer: Low quality is always a problem; low grade may not be a problem
Quality is the degree to which requirements are met, while grade is a category for items with the same functional use but different technical characteristics; low quality is always a problem, but low grade may be acceptable.
Question 7: Which PMBOK process produces the Quality Management Plan as its primary output?
- Manage Quality
- Control Quality
- Plan Quality Management (Correct answer)
- Monitor and Control Project Work
Correct answer: Plan Quality Management
The Plan Quality Management process produces the Quality Management Plan, which describes how quality policies will be implemented and verified throughout the project.
