THE GUIDE
221 pages, 25 chapters, 6 parts
From the verified regulatory framework to the QC laboratory system by system. Every regulatory statement carries the clause, the date and the status of the text behind it.
THE TOOLKIT
18 editable tools, in English and Italian
Eleven Excel workbooks and seven Word documents. No frequency, threshold or retention period is pre-loaded: every site-dependent field sits next to the field for its rationale.
UPDATES
Lifetime, included in the price
When the 2025 EU drafts are adopted, or a source changes edition, you receive the new version of guide and toolkit at no extra cost.
Each tool exists because there is a decision the site has to be able to defend. Supplied in English and in Italian.
EXCEL 01 · Data Integrity Gap AssessmentWhere you stand against the verified clauses, clause by clause, with evidence and residual gap.
EXCEL 02 · Systems and Data Flow InventoryThe perimeter of governed data: where it originates, where it lives, which audit trails exist.
EXCEL 03 · DIRA with scoring and remediation planThe risk assessment that makes every downstream choice defensible.
EXCEL 04 · Audit Trail Criticality MatrixFrom trail criticality to review cadence, with the reasoning kept on the record.
EXCEL 05 · Audit Trail Review RegisterOne register for the whole site: no coverage gaps created by parallel logs.
EXCEL 06 · QC Data Review Checklists by system typeWhat the analyst checks and what the second person checks, system by system.
EXCEL 07 · Access and Privilege ReviewAccounts, roles, administrative privileges and shared logins, reviewed in writing.
EXCEL 08 · Backup and Restore Test LogThe documented restore test, not just the backup that shows as completed.
EXCEL 09 · Retention and Archiving ScheduleEvery retention period sitting next to the source that actually sets it.
EXCEL 10 · 2025 EU Drafts Readiness TableWhat you already do for your own reasons and what you would do only for an unadopted text.
EXCEL 11 · DI Deviation and CAPA TrackerData integrity events from detection through to the effectiveness check.
WORD 12 · SOP Data Governance and Data IntegrityRoles, source citation rules, how data integrity events enter the quality system.
WORD 13 · SOP Audit Trail ReviewHow a trail is actually reviewed: what you look at, how you search, how you record the outcome.
WORD 14 · SOP Data Review in QCPrimary and secondary review of analytical data, printouts and hybrid systems included.
WORD 15 · Audit Trail Review FormThe point evidence of a single review: scope, outcome, date and signature.
WORD 16 · Data Integrity PolicyWhich attribute set the site adopts, from which source and with which status.
WORD 17 · Data Integrity Master PlanRisk, remediation, training, self-inspection and indicators held together in one plan.
WORD 18 · DIRA ReportThe report you put on the table when an inspector challenges a choice.
Eight real situations on the floor, with the tool and the chapter that resolve each one.
HOW THE SOURCES ARE HANDLED
No statement without the clause, the date and the status of the text
- At 6 September 2026 the 2025 EU drafts of Annex 11, Chapter 4 and Annex 22 are not adopted: the text in force is still the Annex 11 of January 2011. In the guide the drafts carry the [DRAFT] label and never enter a requirement.
- The argument that carries the book is a textual verification: no official source sets a numeric audit trail review frequency. Annex 11 clause 9 only says “regularly”; the FDA, in the December 2018 Data Integrity Q&A, ties the review to the record before release. The frequency is justified through risk assessment, and the guide shows how.
- Where sources diverge, the divergence is mapped rather than quietly resolved: 10 documented divergences. MHRA uses ALCOA and not ALCOA+; the 2025 draft Annex 11 uses ALCOA+ with nine attributes while the draft Chapter 4 uses ALCOA++ with ten; no FDA document governs manual integration of chromatographic peaks in a CGMP context.
- 60 sources in the register in Appendix A and 44 documents excluded with the reason stated: superseded editions, documents the industry cites that do not exist, content that cannot be verified. 259 citable clauses consolidated and 1,155 status labels per language.
- No operational value is pre-loaded in the toolkit: where you would expect a number you find a field to complete and, beside it, the field for its rationale. A pre-loaded number becomes the site default that nobody can trace back to a source.
