This is a ready-to-use risk assessment for choosing an electronic signature method, password, biometric, or PKI/digital signature, for a specific signing point or system, so the choice rests on a documented rationale rather than a vendor default or habit. Replace every <<FILL: ...>> placeholder with your own specifics, set your document numbers and dates, and route it through document control and approval. A filled specimen follows. Verify each cited regulation against the current source before you rely on it.

1. Purpose
This assessment determines whether password-based, biometric, or PKI/digital signatures are the appropriate method for <<FILL: SIGNING POINT>>, documenting the reasoning so the choice can be defended in an inspection or audit and revisited if the environment changes.
2. Scope
This assessment covers the signature method decision only. It does not cover signature-to-record binding design, which is validated separately and is independent of authentication method; both are addressed together in the system’s overall electronic signature design per implementing compliant electronic signatures.
3. Responsibilities
| Role | Responsibility |
|---|---|
| System / process owner | Describes the signing environment (gowning, glove use, shared workstations, session volume) that drives the risk factors. |
| Information Security | Assesses credential-sharing risk, privacy/data-protection burden of biometric data, and PKI certificate lifecycle burden. |
| Validation / CSV lead | Facilitates the assessment and ties the selected method to the OQ test scope. |
| Quality Assurance | Approves the method decision and confirms the rationale is documented, not asserted. |
4. Method
4.1 Score each candidate method against the same factors
| Factor | Password (1 = favors, 5 = neutral, 9 = disfavors) | Biometric | PKI / digital signature |
|---|---|---|---|
| Native vendor support in target system | <<FILL>> | <<FILL>> | <<FILL>> |
| Credential-sharing risk in this environment (gowned, gloved, shared terminals) | <<FILL>> | <<FILL>> | <<FILL>> |
| Privacy / data-protection burden | <<FILL>> | <<FILL>> | <<FILL>> |
| Volume of rapid in-session signings | <<FILL>> | <<FILL>> | <<FILL>> |
| Cross-company / regulatory-facing legal weight needed | <<FILL>> | <<FILL>> | <<FILL>> |
| Validation and device-qualification effort | <<FILL>> | <<FILL>> | <<FILL>> |
| Total | <<FILL>> | <<FILL>> | <<FILL>> |
Lower total favors that method for this signing point; do not treat the total as the sole decision, since a single high score on legal weight or credential-sharing risk can outweigh a favorable total elsewhere.
4.2 State the decision and the residual risk
<<FILL: state the method selected, the deciding factor(s), and the residual risk the other methods would have carried>>
4.3 Fallback and enrollment failure path
For biometric or PKI methods, state the compliant fallback for enrollment failures or device outages: <<FILL: e.g. a password path retained for the same signing point, itself meeting section 11.200(a)>>.
5. Assessment table (per signing point, if scope covers more than one)
| Signing point | Environment factors | Method selected | Deciding factor | Fallback method | Residual risk |
|---|---|---|---|---|---|
<<FILL>> | <<FILL>> | <<FILL>> | <<FILL>> | <<FILL>> | <<FILL>> |
6. Acceptance criteria
- Every candidate method is scored against the same factor list, not assessed narratively without a comparable basis.
- The selected method’s deciding factor is stated explicitly, not left to be inferred from the total score alone.
- A compliant fallback exists for any biometric or PKI method, and that fallback itself meets the two-component or equivalent requirement.
- Binding is confirmed as a separate, method-independent control and is not assumed to be solved by the authentication method chosen here.
- The assessment is reviewed if the signing environment changes materially (new workstation model, gowning change, a credential-sharing incident).

Filled specimen
Assessment for a manufacturing execution system’s in-process step release, a high-volume, gowned, gloved environment.
| Factor | Password | Biometric | PKI |
|---|---|---|---|
| Native vendor support | 1 (native) | 5 (add-on module) | 9 (not supported) |
| Credential-sharing risk (gowned/gloved) | 5 (moderate concern) | 1 (largely eliminated) | 5 (moderate) |
| Privacy burden | 1 (low) | 9 (special-category data, glove-compatible reader needed) | 5 (certificate management) |
| Rapid in-session signing volume | 5 (some friction, workable) | 1 (fast with the right reader) | 9 (heavy for high volume) |
| Legal weight needed | 1 (internal only) | 1 (internal only) | 9 (not needed here) |
| Validation / qualification effort | 1 (low) | 9 (device qualification, false-accept/reject characterization) | 9 (certificate lifecycle) |
| Total | 14 | 26 | 46 |
Decision: password-based two-component signatures selected. Deciding factor: native vendor support plus low validation burden outweigh biometric’s credential-sharing advantage, given the environment’s actual sharing risk was assessed as moderate, not severe, and no regulatory-facing legal weight is needed at this signing point. Residual risk: credential sharing between gowned operators remains a monitored risk, mitigated procedurally through training and periodic access review rather than through the authentication method itself.
Common inspection findings this risk assessment prevents
- A signature method chosen by vendor default or habit with no documented comparison against the environment’s actual risk factors.
- Biometric or PKI signatures deployed with no compliant fallback for enrollment failure or device outage.
- Binding assumed to be “handled” because a strong authentication method was chosen, when binding is validated separately.
- Privacy or data-protection review skipped for a biometric rollout because it was treated as a purely technical decision.
How to adapt this risk assessment
- Score every candidate method against the same factor list in section 4.1, even if one method is an obvious front-runner; the record of the comparison is what an inspector wants to see, not just the conclusion.
- State the deciding factor explicitly in section 4.2; do not let a raw score total stand in for reasoning.
- Confirm a compliant fallback exists before deploying biometric or PKI methods.
- Route the assessment through Information Security for the privacy and credential-sharing scoring, not Validation alone.
- Re-run the assessment if the signing environment changes materially.
