This is a ready-to-use validation summary report that closes out a retrospective (retroactive) validation of a legacy GxP computerized system. It states what was done, whether acceptance was met, carries the history and disclosure section on the face of the conclusion, and records QA’s release decision. Replace every <<FILL: ...>> placeholder, set your document numbers and dates, and route it through document control. A worked filled specimen follows. This is general guidance to adapt and verify, not legal or regulatory advice; confirm each cited regulation against the current source before you rely on it.

1. Summary of activity
<<FILL: COMPANY NAME>> performed a retrospective validation of <<FILL: SYSTEM NAME / ID>>, a system already in GxP use, to establish documented evidence that the live system operates correctly and that its records can be trusted. The system was classified <<FILL: Scenario A / B / C>> and remediated by <<FILL: retrospective validation, documentation-led / baseline-led>>. The work comprised a current-state installation qualification, a risk-based operational qualification, and a historical data review, all defined in <<FILL: VP-ID>> and scoped by risk assessment <<FILL: RA-ID>>.
| Deliverable | Reference | Status |

| Risk assessment | <<FILL: RA-ID>> | Approved |
| Validation plan | <<FILL: VP-ID>> | Approved |
| Current-state IQ and risk-based OQ | <<FILL: PROT-ID>> | Executed |
| Historical data review | <<FILL: report ID>> | Complete |
| Disclosure assessment | <<FILL>> | Complete |
2. Results versus acceptance
| Area | Acceptance criterion | Result |
|---|---|---|
| IQ | Verified live configuration baseline, unverifiable values flagged | <<FILL: met / not met>> |

| Historical review | Defined population, justified sample, stated criteria, findings and impact | <<FILL>> |
| Deviations | All resolved before conclusion | <<FILL>> |

| Why prospective validation did not occur | <<FILL>> |
| Uncontrolled changes since (upgrades, migrations, config) | <<FILL>> |
| Historical data review conclusion on record trustworthiness | <<FILL>> |
| Data used in a regulatory submission | Yes / No, <<FILL: which>> |

6. Conclusion and release
Based on the results above, the historical review, and the documented history and disclosure section, <<FILL: SYSTEM NAME / ID>> is <<FILL: fit / not fit>> for continued GxP use, subject to the open limitations in section 5 and to routine change control and periodic review from the effective date of this report.
The system is placed under change control per <<FILL: SOP-ID>> and periodic review per <<FILL: SOP-ID>> with the first review due <<FILL: date>>.

Filled specimen
Illustrative conclusion and history section for CDS-03.
Summary: CDS-03 was classified Scenario B and remediated by baseline-led retrospective validation. Current-state IQ, risk-based OQ, and a stratified historical review were completed under VP-CDS-03 and RA-CSV-021-01.
Results: IQ baseline verified (one flagged item: the audit trail was set to full detail only from the second upgrade). OQ: 5 of 5 critical cases passed; one Medium-risk deviation on report header formatting, corrected and re-executed. Historical review of all release results over the period of concern found no altered results; the reduced-logging window was confirmed and bounded.
History and disclosure: system entered GxP use in 2014 with an IQ/OQ that no longer reflects the current version; two upgrades and a 2019 migration occurred outside formal change control; the historical review supports record trustworthiness with the noted limitation; stability data reached a submission; regulatory affairs reviewed the exposure and concluded no notification was warranted, and documented the decision.
Open limitation: results in the reduced-logging window (Q3 2016 to Q1 2017) are supported by raw data files and second-person review records although the audit trail was thinner; bounded impact, no product-quality effect identified.
Conclusion: CDS-03 is fit for continued GxP use, subject to the one open limitation, and is placed under change control and 12-month periodic review. QA released the system on 18 August 2026.
That shape, an honest history section, a bounded limitation, a cross-functional disclosure decision, and an explicit QA release, is what turns a discovered gap into a corrected one rather than a concealed one.
Common inspection findings this report prevents
- A summary that concludes “validated” without disclosing that the validation was retrospective.
- Open limitations left unstated, so an inspector finds the logging gap the report hid.
- A disclosure decision made by the quality team alone when submissions were involved.
- Release signed by validation or IT rather than by QA.
- No forward controls named, so the system drifts back out of control after release.
How to adapt this report
- Set your document number and link the governing SOP, plan, protocol, and risk assessment.
- Complete the history and disclosure section honestly; it is the part inspectors read first.
- State every open limitation with its bounded impact and its compensating control.
- Route the release signature to QA and, where submissions are involved, capture regulatory affairs concurrence.
- Confirm every regulation in section 7 against the current published version before issue.
