Apply the DQ reasoning

20 distinct application questions. This open-book self-study assessment exposes its answer key in the source and below. The suggested practice target is 85% (17/20), not a regulatory threshold, DQ acceptance rule or proof of independent competence. Unanswered questions must be completed before scoring. Answers are not sent to a server.

1. A team signs DQ after reviewing drawings. Which statement can its conclusion support?
2. The URS has revision 3 but the DQ matrix cites revision 2. What is needed?
3. A vendor guarantees a catalogue maximum volume; the process minimum is undefined. What remains unresolved?
4. Three applicable bounds are ±0.2 °C each. Which conservative total and comparison with the fictional ±0.5 °C requirement are correct?
5. The vendor proposes ±0.1, ±0.1 and ±0.2 °C components. Against the fictional ±0.5 °C limit, what follows?
6. A gasket has a known material name but no product/cleaning compatibility basis. What is justified?
7. An outlet drawing is revised to remove a retained pocket. Which closure is strongest?
8. A control loop and its alarm use a common transmitter. What should the DQ review examine?
9. A fault response inhibits heating, but restart behaviour is unspecified. What action fits DQ?
10. A password is shown on the control screen. What does it demonstrate by itself?
11. A rear instrument cannot be removed after piping is added. Which input was missed?
12. A utility is qualified for its own scope. What else supports a vessel connection?
13. An action owner is assigned for a protective-control gap. How should evidence status change?
14. A low risk total hides a severe effect with uncertain detection. Which response is strongest?
15. The supplier protocol omits an identified sensor-failure challenge. Which action is appropriate?
16. A FAT result is proposed for reuse after a design change. Which question matters most?
17. A required gasket specification is changed during DQ. What preserves traceability?
18. An open design finding is assessed as not significantly affecting the proposed next qualification stage. What supports conditional progression?
19. Eight design rows are supported and two remain open. What is the numerical coverage?
20. What should accompany a DQ package handed to the IQ team?

Answer key and explanations

1. Proposed design suitability was evaluated within the stated scope — Limit the conclusion to the evidence and scope of the design review.

2. Assess the changed requirements and reconcile the review baseline — A revision change can alter the design-review basis.

3. Suitability across the intended operating volume range — Supplier capability cannot define the missing process need.

4. ±0.6 °C; exceeds the illustrative ±0.5 °C requirement — The aligned worst-case sum is ±0.6 °C, exceeding the fictional ±0.5 °C requirement. It does not support the requirement and is not a complete uncertainty budget.

5. The 0.4 °C sum supports review, subject to applicable conditions — The conservative sum is within the teaching limit, but conditions and later verification remain relevant.

6. Request gasket evidence relevant to product and cleaning exposure — Identity is necessary evidence but does not alone prove suitability.

7. Reference the reviewed revision and retain later cleaning verification — The closure needs reviewed evidence and must retain future verification obligations.

8. Whether shared failures undermine the proposed protection — Evaluate the failure mechanism rather than counting devices or labels.

9. Define justified recovery behaviour and link it to later verification — Recovery can affect risk and must be addressed as relevant to intended use.

10. An access feature whose adequacy still requires further assessment — A login feature does not establish full access, record or computerized-system compliance.

11. Maintenance access in the final installed arrangement — Review access with the relevant installed configuration and dimensions.

12. A comparison of utility supply conditions with vessel design needs — System qualification does not automatically establish interface compatibility.

13. Keep the finding unresolved until suitable evidence is reviewed — Ownership and schedule are management information, not evidence of effectiveness.

14. Examine severity, uncertainty and the proposed control evidence — A score alone cannot settle an unsupported high-consequence scenario.

15. Arrange site suitability review and a justified verification supplement — The site must assess protocol suitability and coverage of relevant verification needs.

16. Does the tested configuration and function remain applicable after change? — Evidence reuse depends on applicable configuration, conditions and impacts, not presentation.

17. Retain the prior baseline and reassess affected design conclusions — Controlled history and impact review allow the decision to be reconstructed.

18. Progress after documented impact assessment and stage authorization — Progression is specific to the proposed activity and does not close the design finding.

19. 80% coverage; no percentage establishes design suitability — 8/10 × 100 = 80%; this does not establish suitability or a release threshold.

20. Controlled baseline, open findings and planned verification dependencies — IQ needs the accepted design basis and visibility of unresolved dependencies.
