CPP Quality Management in Procurement 1 — Questions and Answers
Question 1: Which quality management approach focuses on continuous improvement involving all employees and is commonly referenced in procurement contexts?
- Six Sigma
- Total Quality Management (TQM) (Correct answer)
- ISO 9001
- Statistical Process Control
Correct answer: Total Quality Management (TQM)
Total Quality Management (TQM) is an organization-wide philosophy that emphasizes continuous improvement and involvement of all employees, making it a foundational concept in procurement quality management.
Question 2: A procurement professional wants to measure a supplier's defect rate. Which metric expresses defects per one million opportunities and is widely used in quality measurement?
- Cpk index
- DPMO (Correct answer)
- AQL level
- OEE score
Correct answer: DPMO
DPMO (Defects Per Million Opportunities) is the standard metric used in Six Sigma and quality management to express defect rates at a scale of one million, enabling comparison across processes.
Question 3: When a buyer sets a maximum acceptable defect percentage in a shipment before rejection, this threshold is known as:
- Capability index (Cpk)
- Acceptable Quality Level (AQL) (Correct answer)
- Defect density ratio
- Process sigma level
Correct answer: Acceptable Quality Level (AQL)
Acceptable Quality Level (AQL) defines the maximum defect percentage in a batch that is still considered acceptable, guiding sampling plans and inspection decisions.
Question 4: Which ISO standard specifically addresses quality management systems and is most relevant to evaluating a supplier's quality processes?
- ISO 14001
- ISO 45001
- ISO 9001 (Correct answer)
- ISO 31000
Correct answer: ISO 9001
ISO 9001 is the international standard for Quality Management Systems (QMS) and is the primary standard procurement professionals reference when assessing supplier quality capabilities.
Question 5: A supplier scorecard shows that a vendor has a high rate of non-conforming parts. The FIRST corrective action a procurement professional should request is:
- Immediate contract termination
- A root cause analysis and corrective action plan (CAPA) (Correct answer)
- Switching to an alternate supplier without notice
- Reducing the order quantity to minimize risk
Correct answer: A root cause analysis and corrective action plan (CAPA)
A Corrective Action and Preventive Action (CAPA) plan that begins with root cause analysis is the standard first step, allowing the supplier to identify and address the underlying issue.
Question 6: Which quality control tool uses a diagram shaped like a fishbone to identify potential causes of a defect or problem?
- Pareto chart
- Control chart
- Ishikawa (cause-and-effect) diagram (Correct answer)
- Scatter diagram
Correct answer: Ishikawa (cause-and-effect) diagram
The Ishikawa diagram, also called a fishbone or cause-and-effect diagram, visually maps potential root causes of a problem across categories such as people, process, materials, and machinery.
Question 7: In incoming quality control, what is the purpose of a 'First Article Inspection' (FAI)?
- To evaluate supplier financial stability before contract award
- To verify that the first production unit from a supplier meets all specifications before mass production (Correct answer)
- To audit a supplier's environmental practices
- To assess packaging and labeling compliance only
Correct answer: To verify that the first production unit from a supplier meets all specifications before mass production
First Article Inspection (FAI) verifies that the initial production sample from a supplier conforms fully to design and specification requirements before full-scale production proceeds.
