Quality system documentation and outlined structure requirements from 820.186 — but Part 820 never required a quality manual by name.
Quality manual is a new explicit requirement: must define QMS scope, justified exclusions, documented procedures, and a process interaction map.
QMS scope statement, exclusion justifications, and process interaction diagram — the most common structural gap for Part 820-heritage QMS transitions.

QMSR / ISO 13485: §820.186 Quality system record.
ISO 13485: §4.2.1 General, §4.2.2 Quality manual
Requirement text
A quality manual must be established and maintained, covering the QMS scope with any justified exclusions, documenting or referencing required procedures, and describing the interaction between QMS processes.
Why this clause exists
The quality manual is the organizational declaration of how the quality management system is structured: what it covers, what it excludes and why, how processes connect, and where the required procedures are located. Its function is navigation — it allows an auditor, a new employee, or a regulatory inspector to understand the QMS architecture and locate any element within it without requiring a guided tour. The process interaction requirement is architecturally important: ISO 13485:2016 is a process-based standard, meaning it requires the manufacturer to understand and manage the relationships between QMS processes — how complaint inputs flow to CAPA, how design review outputs feed verification, how management review outputs drive resource allocation — not just the existence of isolated procedures. Describing these interactions creates a systemic quality architecture rather than a collection of independent procedures. The exclusion justification requirement reflects the principle that ISO 13485 requirements may be excluded only where they are not applicable to the organization's activities and products, and only where exclusion does not affect the organization's ability to meet applicable regulatory requirements — it prevents manufacturers from claiming inapplicability for requirements that are genuinely burdensome rather than genuinely irrelevant. The quality manual is also the entry point for QMSR compliance under the 820.186 Quality System Record requirement, meaning it serves dual function as the ISO 13485 navigation document and the FDA quality system record.
What changed
§820.186 — Part 820 (legacy)
"Each manufacturer shall maintain a quality system record (QSR). The QSR shall include, or refer to the location of, procedures and the documentation of activities required by this part that are not specific to a particular type of device(s), including, but not limited to, the records required by § 820.20. Each manufacturer shall ensure that the QSR is prepared and approved in accordance with § 820.40."
§4.2.1 / §4.2.2 — ISO 13485:2016 (current)
"4.2.1 General The quality management system documentation (see 4.2.4) shall include: a) documented statements of a quality policy and quality objectives; b) a quality manual; c) documented procedures and records required by this International Standard; d) documents, including records, determined by the organization to be necessary to ensure the effective planning, operation, and control of its processes; e) other documentation specified by applicable regulatory requirements. 4.2.2 Quality manual The organization shall document a quality manual that includes: a) the scope of the quality management system, including details of and justification for any exclusion or non-application; b) the documented procedures for the quality management system, or reference to them; c) a description of the interaction between the processes of the quality management system. The quality manual shall outline the structure of the documentation used in the quality management system."
Δ Quality manual is now an explicit, named document requirement with prescribed content including exclusion justification and process interaction descriptions — far more structured than Part 820's generic QSR.
Common gaps (what we see in audits)
- No Quality Manual Exists — The organization has SOPs, work instructions, and quality records but has never produced a quality manual as a standalone controlled document. This is a binary gap — the document either exists or it does not.
- QMS Scope and Exclusions Not Documented — Even companies with a quality manual or quality policy document have not formally documented the scope of their QMS — which products, sites, and processes are covered — and have not justified any exclusions from ISO 13485 requirements.
- Process Interaction Map Missing — The quality manual exists but does not describe how QMS processes interact with each other. Individual SOPs exist in isolation without documented linkages showing how outputs of one process (e.g., complaint data) feed as inputs to another (e.g., CAPA, management review, risk management updates).
- Missing 'Interaction of Processes' map — The manual lists SOPs but doesn't have a visual or textual 'Process Map' showing how inputs from one (e.g., Design) become inputs for another (e.g., Production). ISO 13485 §4.2.2 requires this description.
- Incomplete scope / exclusions — The manual fails to explicitly define the 'Scope' or justify 'Exclusions' (e.g., 'We don't do design'). ISO 13485 §4.2.2 requires documented scope and rationale for exclusions.
