CAPA Supplier CAPA & External Nonconformances 2 — Questions and Answers
Question 1: What is the primary purpose of verifying effectiveness of a supplier's SCAR response?
- To confirm that the supplier submitted paperwork on time
- To confirm that the corrective actions have eliminated the root cause and prevented recurrence (Correct answer)
- To validate that the supplier's pricing remains competitive after the nonconformance
- To ensure the supplier updated their website with the new quality procedures
Correct answer: To confirm that the corrective actions have eliminated the root cause and prevented recurrence
Effectiveness verification confirms that the implemented corrective actions actually eliminated the root cause and that the nonconformance has not recurred, which is the ultimate goal of any CAPA.
Question 2: Which method is most objective for verifying that a supplier's corrective action prevented recurrence of a dimensional nonconformance?
- Reviewing the supplier's written assurance letter
- Reviewing incoming inspection data from subsequent lots for conformance to the dimension (Correct answer)
- Asking the supplier's sales representative to confirm the fix verbally
- Checking that the supplier updated their quality manual
Correct answer: Reviewing incoming inspection data from subsequent lots for conformance to the dimension
Incoming inspection data from subsequent lots provides objective, data-driven evidence that the nonconformance has not recurred, making it the most reliable effectiveness verification method.
Question 3: A supplier submits a SCAR response attributing a defect to 'operator error' without further depth. What is the most significant weakness of this root cause?
- It does not specify the operator's name and employee ID
- It identifies a symptom rather than the systemic root cause that allowed the error to occur (Correct answer)
- It fails to mention the specific machine used during production
- It was not written by a certified quality engineer
Correct answer: It identifies a symptom rather than the systemic root cause that allowed the error to occur
'Operator error' is a symptom-level finding; an adequate root cause analysis must identify why the system failed to prevent the error, such as inadequate training, unclear instructions, or missing mistake-proofing.
Question 4: A supplier has received three SCARs in six months for the same type of defect. What quality management action is most appropriate?
- Issue a fourth SCAR with a shorter response deadline
- Conduct a supplier audit or re-qualification assessment to evaluate systemic quality issues (Correct answer)
- Reduce the incoming inspection sample size to lower detection costs
- Waive future SCARs since the defect type is already documented
Correct answer: Conduct a supplier audit or re-qualification assessment to evaluate systemic quality issues
Recurring nonconformances of the same type indicate that previous corrective actions were ineffective and a deeper systemic audit or re-qualification is necessary to assess the supplier's quality system.
Question 5: In a supplier quality scorecard, which key performance indicator (KPI) most directly reflects CAPA effectiveness?
- Supplier's annual revenue growth percentage
- Defective parts per million (DPPM) trend over time (Correct answer)
- Number of SCARs issued to the supplier in a quarter
- Supplier's on-time delivery rate
Correct answer: Defective parts per million (DPPM) trend over time
DPPM trend over time reflects whether defect rates are declining after corrective actions, making it the most direct indicator of CAPA effectiveness in supplier quality performance.
Question 6: What does 're-qualification' of a supplier typically involve in the context of repeated quality failures?
- Renegotiating the supplier's contract pricing
- Re-evaluating the supplier's quality system, capabilities, and processes to determine continued approved status (Correct answer)
- Requiring the supplier to resubmit their W-9 tax form
- Re-sending the original purchase order to reset delivery timelines
Correct answer: Re-evaluating the supplier's quality system, capabilities, and processes to determine continued approved status
Re-qualification involves a comprehensive re-evaluation of the supplier's quality management system and manufacturing capabilities to determine whether they should retain approved supplier status.
Question 7: How does closed-loop supplier CAPA data benefit an organization's overall quality management system (QMS)?
- It reduces the need for internal audits by outsourcing quality to suppliers
- It feeds into management review, supplier performance trends, and risk-based procurement decisions (Correct answer)
- It eliminates the requirement for incoming inspection of supplier materials
- It automatically generates purchase orders for replacement parts
Correct answer: It feeds into management review, supplier performance trends, and risk-based procurement decisions
Closed-loop supplier CAPA data provides trend information that informs management review, risk-based sourcing decisions, and supplier development programs, strengthening the entire QMS.
