Module 02 / Final self-assessment

Test the decisions, not just the terms

20 questions · Suggested practice target: 80% (16/20). Review explanations and retry as needed.

This is a learning target, not a regulatory threshold or formal competency assessment. Unanswered questions must be completed before scoring. Responses are not sent to a server. This is an open-book self-study exercise: answers and explanations are visible in the page source and downloadable key. Scores do not demonstrate independent competence. Read the lesson notes and required extensions where provided before attempting it.

1. V-201 has a purchase order but no agreed operating range. What should the team do before writing acceptance tests?
2. A VMP lists protocols but gives no qualification status. Which change best supports the next-stage decision?
3. The jacket utility is outside the vessel boundary. Its availability affects temperature control. What belongs in the plan?
4. For the separate PB-02 teaching assumption (provisional ±0.5 °C, still requiring justification and approval), which draft requirement is measurable?
5. The installed sensor differs from the sensor in a passing FAT report. How should URS verification be recorded?
6. An agitator trip may cause non-uniform concentration. Which statement describes a potential patient harm?
7. Two FMEA rows both score 6, but one has severity 3 and the other severity 1. What is defensible?
8. An alarm and controller share one sensor. Which evidence addresses the claimed protection?
9. A measured error is −0.6 °C and the illustrative absolute limit is 0.5 °C. What is the numerical result?
10. Hose cleaning evidence is missing, but a proposed dry simulation never uses the hose. What is the best next step?
11. The URS was revised after DQ approval. Which status is most defensible?
12. The jacket utility is qualified, but its supply conditions differ from the vessel design assumptions. What is needed?
13. Draft PB-02 proposes ±0.5 °C but the base project has no approved temperature tolerance. What is URS-02 status?
14. A supplier FAT passed, but the installed controller firmware differs. Which decision is defensible?
15. An FMEA detection score is reduced after an alarm is proposed but not challenged. What is the issue?
16. An independent low-speed detector is proposed for the agitator. Which verification best supports independence?
17. A signed error dataset sums to +3.1 °C across ten readings. What is its signed mean?
18. With an illustrative absolute limit of 0.5 °C, how many listed errors exceed the limit?
19. A new product changes cleaning needs. Which action is justified?
20. What does completing this self-study module demonstrate?

Printable answer key and explanations

1. Agree intended use and justify the required operating range — A supplier capability or another project does not establish this process need.

2. Link system status to evidence and outstanding actions — Decision makers need evidence-linked status and remaining work.

3. A utility interface owner and relevant qualification evidence — Define interface dependencies and responsibilities rather than leaving a boundary gap.

4. Error shall stay within ±0.5 °C at defined reference points — The last option is measurable, once the fictional basis, points and method are approved; ±0.5 °C is not a general GMP limit.

5. Keep it open while applicability and affected tests are assessed — A changed measurement chain needs an applicability assessment and affected verification.

6. An incorrect dose produces an adverse patient effect — Distinguish patient harm from equipment failure and detection failure.

7. Examine severity, evidence and controls before deciding — An ordinal product can conceal important differences.

8. A challenge of the shared fault and resulting response — Functional testing must address the shared dependency, not merely documentation or configuration.

9. Exceeds: its magnitude is greater than 0.5 °C — Use absolute magnitude for a two-sided error limit; apply the approved uncertainty/decision rule in real testing.

10. Assess simulation impact and seek authorization for that stage — Conditional progression concerns a specific activity and requires justified impact assessment and authorization.

11. Assess the URS change and revisit affected DQ evidence — A change to user requirements can affect the design qualification basis.

12. Assess interface compatibility and affected verification — Qualification of a supplying system does not establish its suitability for every receiving interface.

13. Pending justification and approval of the acceptance basis — Teaching assumptions cannot replace authorized project requirements.

14. Assess firmware impact and FAT applicability to site tests — Supplier results require documented applicability to the installed configuration.

15. The revised score lacks evidence of control effectiveness — Residual risk scoring should follow evidence of effectiveness, not an untested proposal.

16. Challenge primary-sensor failure and verify independent detection and inhibition — The verification should challenge the common-cause scenario and protective response.

17. +0.31 °C — The signed arithmetic mean is +3.1/10 = +0.31 °C.

18. One — Only 0.6 °C exceeds the illustrative limit; 0.5 °C equals it.

19. Reassess intended use, risks, requirements and affected evidence — New intended use may affect linked requirements and qualification evidence.

20. Completion of self-study, with competence needing separate evaluation — Formal competency and authorization require an applicable independently approved process.
