Documentation and Evidence Architecture

Research basis: 2026-07-23, extended 2026-07-26 for laboratory lanes. This is a process-oriented planning reference, not a list of copyrighted ISO or IEC requirements.

The five-layer hierarchy below applies to every standard this skill covers. Where the wording is device-specific, the laboratory equivalent is noted; for depth read references/iso-17025.md or references/iso-15189.md.

Do not use a fixed “31 procedures” claim

ISO 13485 does not require one universal package of a fixed number of separately titled procedures for every organization. Document architecture depends on QMS scope, products, lifecycle activities, sites, outsourced processes, applicable regulatory requirements, and how controlled processes are combined or split.

Avoid:

• declaring a QMS complete because a named-document count was reached;
• equating a filename or keyword hit with implementation;
• treating an example document name as mandatory;
• labeling every conditional process “not applicable” without an authorized decision;
• assuming one regime's records satisfy another regime; or
• claiming certification/readiness from document presence.

Use an authorized copy of ISO 13485 and current jurisdiction/product sources to identify the documentation and records that actually apply. ISO publications are copyrighted; see ISO copyright.

Controlled evidence hierarchy

1. Source and applicability layer

Maintain:

• dated official-source ledger with exact edition/version;
• product/site/market/lifecycle scope intake;
• authorized applicability and not-applicable decisions;
• regulatory/product-requirements matrix;
• certification, MDSAP, FDA, and EU assurance-route distinctions;
• source-change monitoring and impact assessments.

Minimum fields: source ID, publisher, title, edition/version/date, authorized location, access date, owner, status, currency-review date, impact record, and approval.

2. Governance and policy layer

Typical controlled documents and records:

• QMS scope and quality manual or equivalent policy architecture;
• quality policy/objectives and measures;
• organization chart, role authorities, delegates, independence, and escalation;
• authorized management representative appointment;
• process-interaction map;
• management review plan, records, decisions, and follow-up.

The quality manual is not evidence that the processes operate. Link it to approved procedures and sampled implementation records.

3. Process-control layer

An organization may combine or separate controlled procedures. Use titles that match actual work. At minimum, assess whether controlled documentation is needed for:

• document, record, and external-source control;
• risk management;
• design and development, transfer, and design change;
• customer/product requirements and communications;
• suppliers, purchasing, outsourced processes, and acceptance;
• production, service, infrastructure, environment, and maintenance;
• process, equipment, test-method, and software validation;
• monitoring/measurement equipment;
• identification, traceability, preservation, installation, and servicing;
• feedback, complaints, postmarket surveillance, and vigilance/reporting;
• nonconforming outputs, corrections, removals/advisory actions, and CAPA;
• internal audit, data/trend analysis, and management review;
• competence, training, authorization, and awareness; and
• QMS/product/process/source/software change control.

Each controlled process should identify purpose, scope, roles, inputs, outputs, methods, decision criteria, records, interfaces, measures, change controls, source/version basis, approval, and effective date.

4. Product and technical evidence layer

Maintain a controlled file architecture for each applicable product/type/family. Depending on product and jurisdiction, evidence may include:

• product description, intended purpose/use, claims, variants, accessories;
• classifications and authorized decision records;
• requirements/specifications and acceptance criteria;
• risk management and benefit-risk evidence;
• design planning, inputs, outputs, reviews, verification, validation, transfer, and changes;
• production, supplier, packaging, labeling, installation, and service information;
• software lifecycle, cybersecurity, usability, biocompatibility, electrical safety, sterilization, clinical/performance, and other product-specific evidence;
• acceptance/release and distribution/traceability records;
• postmarket plans, reports, complaints, vigilance, field actions, and updates.

Do not claim that an ISO 13485 “medical device file” automatically replaces every FDA, EU, or other jurisdiction-specific file or record concept. Build a cross-reference that preserves each required record and its source/version.

Laboratory equivalent. For ISO/IEC 17025 and ISO 15189 the technical evidence layer is organized per scope item — per method, measurand, or examination — rather than per product family. Depending on the activity it may include:

• the controlled method or examination procedure and its issue, with the authorization to put it into service;
• verification or validation evidence: performance characteristics evaluated, acceptance criteria, data, and approval;
• the measurement-uncertainty evaluation and its stated basis;
• metrological traceability evidence: stated reference, provider and its accreditation scope, certificate identity, uncertainty carried forward, interval justification, and intermediate checks;
• the documented decision rule and customer-agreement record where conformity is stated;
• proficiency-testing or external-quality-assessment enrolment, results, evaluation against criteria, and investigation of unsatisfactory outcomes;
• equipment, reagent, consumable, and reference-material records;
• technical records sufficient to reproduce the reported result; and
• report and certificate templates, amendment/retraction handling, and authorized signatories.

An accredited scope schedule is not this layer — it is the output of the accreditation body. Keep the two apart in the register.

5. Implementation-record layer

Procedures describe controls; records show what happened. Sample actual records for:

• approvals, revision/effective status, training, and point-of-use control;
• competence and role authorization;
• management review inputs, decisions, resources, actions, and follow-up;
• internal audits, findings, corrections/CAPA, and effectiveness;
• risk reviews and links to design/production/postmarket changes;
• design reviews, verification, validation, transfer, and changes;
• supplier qualification, agreements, monitoring, change notices, re-evaluation, nonconformity, and CAPA;
• production/service work, process parameters, acceptance, release, validation, revalidation, maintenance, and calibration;
• software intended use, risk, validation, release, incidents, and changes;
• identification, traceability, distribution, installation, and service;
• complaints, investigations, reportability/vigilance decisions, and communications;
• nonconformity, disposition, corrections, CAPA, and effectiveness; and
• data analysis, trends, objectives, escalation, and change decisions.

Fail-closed document register

For every controlled document, capture:

• unique ID, title, type, owner, revision, and status;
• source/version references and change rationale;
• reviewers/approvers and approval evidence;
• effective date and training impact;
• linked documents, forms, records, systems, products, suppliers, and processes;
• obsolete/superseded disposition; and
• controlled location and access classification.

For every record series, capture:

• owner, record type, creation/attribution method, and status;
• integrity, security, audit trail, backup/recovery, retrieval, and correction controls;
• exact retention period and approved basis;
• disposition method and authorization;
• applicable products/sites/jurisdictions;
• evidence samples and approval.

Unknown, placeholder, unapproved, uncontrolled, or inaccessible entries are gaps—not assumed evidence.

Regime-specific supplements

ISO certification

Maintain the authorized standard edition, certification scope, sites/activities, certification-body and accreditation-scope evidence, audit program, findings, and certificate status. A certificate is limited to its scope and is not a product or regulatory authorization.

Laboratory accreditation (ISO/IEC 17025, ISO 15189)

Maintain the authorized standard edition, the scope of laboratory activities as declared and as accredited, per-location coverage, the accreditation body and its own recognition status, assessment history and findings with their closure evidence, and current accreditation status including any suspension or scope reduction.

Additional controls specific to this lane:

• Claim control. Record where accreditation symbols and endorsement wording may and may not be used, and who authorizes each use. Work outside the accredited scope must carry no accreditation claim. Since 2026-01-01 the recognition arrangement sits with Global Accreditation Cooperation Incorporated — verify current wording rather than reusing legacy ILAC MRA / IAF MLA phrasing.
• Scope-change control. New methods, extended ranges, new locations, and new authorized signatories are scope questions for the accreditation body, not only internal change control. Keep the notification and approval records.
• Authorized signatories. Maintain the current list, the scope each is authorized for, and the competence evidence behind each authorization.
• Subcontracting and referral. Record the provider, its own accreditation or licensure status, the customer-notification basis, and how results are reported.

For ISO 15189 specifically, keep CLIA, licensure, and payer evidence in a separate register. ISO 15189 accreditation does not satisfy CLIA, and blending the two produces a register that implies an equivalence that does not exist. See references/iso-15189.md.

FDA QMSR

Since 2026-02-02, use current 21 CFR Part 820, the incorporated ISO edition, current FDA supplemental provisions, and other applicable FDA regulations. FDA now uses Compliance Program 7382.850, not QSIT. Keep evidence for current complaint, servicing, labeling/packaging, and other FDA-specific requirements. Do not retain old QSR section numbers as the current control model.

FDA's QMSR FAQ states that investigators may review pre-effective-date QMS records and management, quality-audit, and supplier-audit reports. Prepare controlled retrieval without rewriting history or backdating records.

MDSAP

Use the current MDSAP AU P0002.010 Audit Approach, dated 2026-02-02, and the current MDSAP document library. Record participating jurisdictions, products, sites, recognized Auditing Organization, audit cycle, jurisdiction-specific evidence, findings, and action status. Do not substitute an ISO-only certificate or FDA inspection checklist.

EU MDR/IVDR

Keep the current consolidated regulation, conformity-assessment route, device classification, technical documentation, QMS, clinical/performance, postmarket, vigilance, registration/UDI, economic-operator, and notified-body evidence as applicable. Verify notified-body designation and codes in NANDO. MDCG guidance is useful but nonbinding; record document number, revision, date, and impact.

For European standards, distinguish ISO publications from EN adoptions, corrigenda, and European A11 amendments. Verify current OJEU citations on the Commission's harmonised standards page.

Retention: no universal period

Do not use generic “5–10 year” statements or “device lifetime” as a complete retention schedule. For each record type, authorized reviewers should reconcile:

• current standard and regulatory sources;
• product/device lifetime and market-specific periods;
• complaint, vigilance, traceability, clinical/performance, technical-documentation, and certificate obligations;
• legal hold, privacy, contract, and business requirements; and
• system migration and durable retrieval.

Record the chosen period, start event, source/version, rationale, owner, approval, disposition method, and hold override.

Evidence-quality gate

A document or record is ready for substantive human review only when:

• scope and applicability are resolved or explicitly blocked;
• owner and status are clear;
• referenced controlled revision exists;
• approval and effective dates are recorded;
• implementation evidence is sampled;
• source versions are current and traceable;
• open findings and change/CAPA links are visible; and
• the artifact makes no unsupported compliance, conformity, certification, or readiness claim.
