This is a ready-to-use checklist for one hybrid record, run by the second-person reviewer before the record is used to support any decision. It executes the reconciliation defined in the hybrid record control and reconciliation SOP and turns it into a set of questions with a recorded answer, so that a reviewer’s signature is backed by visible evidence rather than by assertion. Replace every <<FILL: ...>> placeholder, set your document numbers, and route the checklist through your normal document control. A filled specimen follows. Verify each cited regulation against the current source before you rely on it, and adapt this to your own processes rather than treating it as legal or regulatory advice.
The single rule that shapes the whole checklist: start from the electronic side and make the paper account for it. Starting from the paper only ever confirms that the paper is complete, and the paper is the half designed to look complete.

When to use this checklist
Run it once per hybrid record, at the point of second-person review, before the result, batch step, or dataset is used to support a decision. Run it in full for every record from a hybrid classified High criticality in the hybrid inventory register. For Medium and Low criticality hybrids, run the sections your procedure specifies and record the sections marked NA with the reason. Do not run it retrospectively as a paperwork exercise weeks after the activity; the value of the check comes from the operator still being available to explain an exception.
Before you start
Have all of the following in hand. If any item is missing, stop and record the reason; a reconciliation performed without the electronic source is not a reconciliation.
| Item | Where it comes from |
|---|---|
| The paper half in original form, all pages | The executing area, not a photocopy unless the copy is certified |
| The governing electronic record, opened in the system | <<FILL: system name>>, with read access for the reviewer |
| The audit trail for the activity period | Same system, exported or viewed on screen |
| The hybrid inventory entry, including the declared governing record | <<FILL: register document number>> |
| The applicable method, batch record instruction, or protocol | Document control |
| Any deviation, investigation, or change record cited on either half | <<FILL: quality system name>> |
How to complete
- Enter the record identification block.
- Work sections A to G in order. Do not skip forward; the count check in section B changes what you look for in every later section.
- Mark each item Pass, Fail, or NA. NA requires a reason on the same line. A blank is not an answer.
- Any Fail stops the review at that point for that item and routes to section H. Continue the remaining items so the full picture is captured, but do not sign the record as reconciled.
- Complete the exception log, the disposition, and the signoff.
Record identification
| Field | Entry |
|---|---|
| Activity and record identifier | <<FILL>> |
| Hybrid inventory reference | <<FILL: HYB-ID>> |
| Declared governing record | <<FILL: electronic / paper / split-field>> |
| Electronic system and identifiers | <<FILL>> |
| Paper form or record number, pages | <<FILL: form ID, page N of M>> |

| Executed by | <<FILL>> |
| Reviewer | <<FILL>> |
| Review date | <<FILL>> |
Section A: setup and provenance
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| A1 | The hybrid inventory entry exists and its declared governing record matches what you are treating as governing today | That the record is a recognised, controlled hybrid and not an undeclared one | ||||
| A2 | You opened the governing electronic record in the system, not a printout or an export someone handed you | Original: review of a copy cannot detect what the copy omitted | ||||
| A3 | You started this review from the electronic side | Effectiveness of review: paper-first review confirms only paper completeness | ||||
| A4 | The paper half is the original controlled form, all pages present, page numbering reads “N of M” and reaches M | Complete: a removed page is only detectable against a stated total | ||||
| A5 | The controlled form number is within the issued range for this activity per the form issuance record | Complete: an unissued or unreconciled form is an uncontrolled record | ||||
| A6 | The applicable method, instruction, or protocol version cited on the record is the version that was effective on the activity date | Accurate: execution against a superseded instruction |
Section B: count
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| B1 | The number of electronic events in the period equals the number of paper entries | Complete: the primary detector of missing or added activity | ||||
| B2 | The count includes blanks, standards, controls, system suitability, and bracketing entries, not only reportable samples | Complete: partial counting hides discarded work | ||||
| B3 | Every aborted, failed, cancelled, or terminated electronic event appears on the paper | Complete: aborted runs absent from paper is the classic testing-into-compliance pattern | ||||
| B4 | Every repeat or re-run on either half is present on both, and each repeat states why it was repeated | Complete and Accurate: an unexplained repeat is an untested result selection | ||||
| B5 | Any machine-generated sequential counter runs without a gap across the period | Complete: a counter gap is discarded data until demonstrated otherwise | ||||
| B6 | Where a counter gap exists, the explanation is recorded on the record and is consistent with the electronic evidence | Complete: an explanation asserted verbally is not evidence |
Section C: identity
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| C1 | Each electronic result maps to exactly one paper entry using the machine-generated identifier named in the inventory | Attributable and Complete: prevents silent swapping of results between records | ||||
| C2 | No electronic event lacks a paper counterpart (no orphan on the electronic side) | Complete: an orphan electronic event is activity nobody recorded | ||||
| C3 | No paper entry lacks an electronic counterpart (no orphan on the paper side) | Accurate: a paper entry with no electronic source may be transcribed from nowhere | ||||
| C4 | The identifier on the paper was copied accurately, character for character, from the electronic output | Accurate: a mistyped identifier breaks the link the whole control depends on | ||||
| C5 | The record identifier appears on every page of the paper half, not only the first or the signature page | Original: prevents a page being substituted or a signature page being transferred | ||||
| C6 | Sample, subject, batch, or material identity on the paper matches the electronic record exactly, including any suffix or preparation designator | Accurate: identity mismatch is a result assigned to the wrong thing |
Section D: value
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| D1 | Every value transcribed from the electronic source to paper was verified against the source during this review | Accurate: transcription without verification is the most common error class in hybrids | ||||
| D2 | Transcribed values match to the full number of significant figures reported by the system, with no silent rounding | Accurate: rounding introduced at transcription changes reported results | ||||
| D3 | Units on paper match the units the system reported | Accurate: unit substitution is a recurring root cause in real investigations | ||||
| D4 | Calculations performed on paper were independently recalculated during this review | Accurate: the arithmetic is part of the record | ||||
| D5 | Where no transcription occurs because the output is attached or printed directly, the attachment is the actual output for this record and is legible | Original and Legible: attached but unreadable is a failed record | ||||
| D6 | Any value that appears on both halves is identical on both | Consistent: divergence between halves is the defining hybrid failure |
Section E: time and sequence
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| E1 | The order of events on paper matches the order recorded electronically | Consistent: reordering after the fact | ||||
| E2 | Each paper entry time falls within the corresponding electronic event window, not before it | Contemporaneous: an entry timed before its event was written from expectation, not observation | ||||
| E3 | No block of paper entries carries a single identical time or handwriting pattern suggesting end-of-shift completion | Contemporaneous: backfilling from memory | ||||
| E4 | The instrument or system clock was not changed during the activity period, per the audit trail | Contemporaneous: an unlogged clock change makes sequence unprovable | ||||
| E5 | Where paper and electronic clocks are independent, the recorded offset between them is within <<FILL: acceptable offset, e.g. 5 minutes>> | Consistent: an uncontrolled offset defeats sequence reconstruction | ||||
| E6 | Any late entry on the paper carries both the event time and the entry time, with a reason | Contemporaneous: the controlled late entry is acceptable, an undisclosed one is not |
Section F: audit trail
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| F1 | The audit trail was enabled and complete for the entire activity period, with no gap or disabled interval | Complete: a gap invalidates every downstream check | ||||
| F2 | Deletions of data, files, sequences, or samples in the period are identified, and each is explained on the paper record or in an approved deviation | Complete: undisclosed deletion is a data integrity event, not a documentation issue | ||||
| F3 | Reprocessing, re-integration, manual integration, and method or sequence edits are identified and each carries a recorded reason | Accurate: undisclosed reprocessing is the finding this whole control exists to catch | ||||
| F4 | Each recorded reason was assessed against the method or instruction, not merely noted as present | Effectiveness of review: a reason that nobody evaluated is decoration | ||||
| F5 | Renamed, copied, or relocated files in the period are identified and explained | Original: renaming is how a failing result becomes an unremarkable one | ||||
| F6 | User account, role, or privilege changes in the period are identified and were authorised | Attributable: privilege escalation during the activity window | ||||
| F7 | Every electronic action in the period resolves to a named individual, and that individual matches the person who signed the paper for the same step | Attributable: the shared-login failure mode |
Section G: exceptions
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| G1 | Every aborted, repeated, out-of-sequence, or invalidated event is explained on the record | Complete: exceptions are where reconciliation is most often skipped | ||||
| G2 | Every correction on paper follows the single-line cross-out convention, leaving the original legible, with initials, date, and reason | Legible and Original: obliteration reads as concealment | ||||
| G3 | Every correction that affects a value appearing on both halves was propagated to both halves and cross-referenced | Consistent: a one-sided correction creates a permanent discrepancy | ||||
| G4 | Every deviation, investigation, or out-of-specification reference cited on either half resolves to a real, retrievable record | Available: dangling references are common and easy to check | ||||
| G5 | No blank mandatory field remains, and every intentionally blank field carries a justified NA rather than being left empty | Complete: an empty field cannot be distinguished from an omitted step |
Section H: signature and link
| # | Check | What it tests for | Pass | Fail | NA | Evidence or comment |
|---|---|---|---|---|---|---|
| H1 | Every signature carries the printed name of the signer, the date, and the stated meaning of the signing | Signature manifestation, consistent with 21 CFR 11.50 | ||||
| H2 | The reviewer signature meaning explicitly includes reconciliation and review of the electronic audit trail | Effectiveness of review: a meaning that omits this permits paper-only review | ||||
| H3 | Every signature and initial resolves to an entry in the specimen signature register | Attributable | ||||
| H4 | The paper identifies the specific electronic record it approves by the machine-generated identifier, so the signature could not be transferred to a different record | Signature and record linking, consistent with 21 CFR 11.70, which covers handwritten signatures executed to electronic records | ||||
| H5 | The signed page is the substantive page or is bound to it by page numbering and the record identifier, not a detachable standalone cover sheet | Signature and record linking: a liftable signature page is a weak link | ||||
| H6 | Execution and review were performed by different individuals, and the reviewer did not perform the work being reviewed | Independence of the second-person check | ||||
| H7 | Where the electronic system supports it, the electronic record notes that a paper approval exists and where it is filed | Available: the electronic record is otherwise silently missing half its approval history |

<<FILL>> | <<FILL>> | <<FILL>> | <<FILL>> | <<FILL>> | <<FILL>> |
Escalation triggers
Apply the classification below and act accordingly. Notify Quality Assurance the same working day for any classification other than “control functioned”.
| What was found | Classification | Action |
|---|---|---|
| A transcription error found and corrected by this check | Control functioned | Record, trend, no deviation |
| A transcription error that did not affect any result or decision | Documentation error | Deviation, retraining, trend for a pattern |
| A transcription error that changed a result, a calculation, or a disposition | Significant | Deviation with impact assessment; widen the review to the surrounding period |
| Reconciliation was not performed previously although the halves agree | Procedural failure | Deviation; the control was absent and agreement this time is not evidence the control works |
| A gap in a counter, a sequence, or page numbering that nobody can explain | Potential lost data | Investigate as potentially discarded data until demonstrated otherwise |
| An orphan electronic event with no paper trace | Potential lost data | Investigate; do not close on the basis that the paper looks complete |
| Any Fail on F2, F3, F5, F6, or F7 that cannot be explained from the record | Potential data integrity event | Escalate immediately per <<FILL: SOP-ID for data integrity events>>. Do not close as a routine deviation. Preserve the electronic evidence before further work on the system. |
| Any Fail on H4 or H5 | Signature link weakness | Deviation; assess whether prior records share the same weakness |
Affected data is not released or used until every exception is resolved and dispositioned.

| Field | Entry |
|---|---|
| Total items applicable | <<FILL>> |
| Pass | <<FILL>> |
| Fail | <<FILL>> |
| NA (with reasons recorded) | <<FILL>> |
| Overall outcome | Reconciled / Reconciled with exceptions closed / Not reconciled, held |

Acceptance criteria
The reconciliation is acceptable when all of the following hold:
- The reviewer opened the governing electronic record and its audit trail, and the review began there.
- Count, identity, value, time and sequence all reconcile, and every difference was investigated and dispositioned rather than noted.
- Every critical audit trail entry in the period was identified and its recorded reason was assessed, not merely observed to exist.
- Every electronic action resolves to a named individual matching the paper signature for the same step.
- Every signature carries a printed name, a date, and a stated meaning that includes reconciliation and audit trail review.
- No item is blank. Every NA carries a reason.
- A different qualified person could repeat this checklist from the record alone and reach the same conclusion.

What makes this specimen defensible is not that it is clean, because it is not. The aborted injection is visible on both halves and linked to its repeat. The manual integration carries a reason that the reviewer actually assessed against the method rather than noting that a reason was present. And the one Fail is an honest recording of a known gap, with evidence that the compensating control operated on this specific day, rather than a Pass awarded because the gap is already on a list somewhere. A reviewer who had signed only the worksheet would have seen eleven tidy results and no evidence that a twelfth injection ever existed.
Common inspection findings this checklist prevents
- The reviewer signed the paper record but cannot demonstrate that the electronic audit trail was ever opened.
- Aborted, repeated, or reprocessed runs exist electronically and appear nowhere on the paper record.
- A gap in a printout counter, a result ID series, or worksheet page numbering is present and unexplained.
- Values were transcribed from the electronic source with no independent verification, and an error changed a reported result.
- A manual integration or reprocessing carries a reason that nobody evaluated against the method, so the reason exists but the review did not.
- A correction was made on one half of the record and never propagated to the other.
- Ink signatures approve electronic records with nothing linking the signature to the specific record it approves.
- The same person executed and reviewed the work, so the second-person check never happened.
- Review records are complete and uniformly clean across a period in which the system logged aborted runs, which tells an inspector the review is a formality.
How to adapt this checklist
- Set your document number and point the parent SOP field at your real hybrid control procedure.
- In section C, replace the generic phrase “machine-generated identifier” with the actual identifier each of your systems produces. Doing this once per system, in the hybrid inventory register, and then citing it here keeps the two documents consistent.
- Set the acceptable clock offset in E5 from your time synchronisation procedure rather than picking a number here.
- Decide which sections apply to Medium and Low criticality hybrids and state that mapping in the parent SOP, so reviewers are not making that judgement per record.
- If your hybrid is a paper batch record dependent on a historian, add items under section B and F that name the specific electronic extracts the reviewer must attach: the trend for the batch window, the alarm and event list, and the operator action log.
- If your hybrid is clinical, replace the sample and injection language in sections B and C with subject, visit, and form identifiers, and add an item confirming that the fields designated as direct data capture in the source data agreement were not also recorded on paper.
- Print the reviewer signature meaning on the form itself rather than relying on the reviewer to write it, and check that the existing form has room for it.
- Confirm every regulation in the references section against the current published version before issue.
