QMSR / ISO 13485: §820.70
ISO 13485: §7.5.1
Requirement text
Production and service provision shall be carried out under controlled conditions, including availability of documented information defining product characteristics, work instructions where necessary, use of suitable equipment, implementation of monitoring and measurement activities, and implementation of product release and delivery activities.
What changed
Part 820 section 820.70 required that production processes be conducted according to documented instructions and controlled conditions. It specified requirements for building specifications, production methods, production procedures, and workmanship standards. Subsections addressed production equipment (820.70(g)), manufacturing material (820.70(h)), and environmental controls (820.70(c)(d)). The regulation was prescriptive about work instructions being available at the point of use.
ISO 13485:2016 clause 7.5.1 provides a more systematic framework for production and service provision under controlled conditions. It requires: availability of information describing product characteristics, availability of work instructions as necessary, use of suitable equipment, availability and use of monitoring and measuring equipment, implementation of monitoring and measurement, and implementation of defined operations for labeling, packaging, release, delivery, and post-delivery. The clause also requires documented requirements for infrastructure maintenance (including adjustments and intervals) when maintenance could affect product quality.
The QMSR adopts ISO 13485 clause 7.5.1 for general production controls. The structural change is significant: where Part 820 had separate subsections for different aspects of production control, ISO 13485 consolidates these under a single clause with a more holistic view. The practical impact is that manufacturers need to ensure their work instructions and process controls address all elements of 7.5.1 comprehensively, not just the narrow elements that were separately called out in Part 820. Equipment maintenance, which was a brief mention in 820.70(g), becomes a more explicit requirement under 7.5.1 with defined intervals and activities.
Atomic constraints
- •Work instructions must be documented and available at the point of use for all production operations.
- •Production procedures must define the sequence of operations, materials, equipment, and acceptance criteria.
- •Product release procedures must define the authorized release activities before distribution.
- •Production records must be maintained demonstrating process execution per defined procedures.
- •Production monitoring and measurement activities must be implemented per the quality plan.
Common gaps
Work Instructions Not Available at Point of Use
moderateWork instructions exist in a document management system but are not physically or electronically accessible at the production workstation. ISO 13485 clause 7.5.1 requires work instructions to be available as necessary during production operations.
Incomplete Equipment Maintenance Program
moderateProduction equipment maintenance is reactive rather than preventive. ISO 13485 clause 7.5.1 requires documented requirements for infrastructure maintenance activities, including defined intervals, that could affect product quality. Many Part 820-era programs lack defined maintenance schedules with documented intervals and acceptance criteria.
Missing Monitoring and Measurement Implementation
moderateProduction procedures define what to produce but lack in-process monitoring and measurement steps. ISO 13485 clause 7.5.1 requires implementation of monitoring and measurement activities during production, not just at final inspection.
Undefined in-process inspection points
moderateWork instructions describe *how to build* but lack specific *inspection steps* (what to check and when). ISO 13485 §7.5.1 requires monitoring of product characteristics.
No Defined Product Release Authorization Process
minorProduction procedures do not clearly define who is authorized to release product at each stage, and under what conditions product can proceed to the next operation. Informal release practices without documented authorization create compliance and traceability gaps.

Audit defense
Production of [your product] is controlled through documented work instructions and procedures in [your document ID]. Each production operation has documented work instructions available at the point of use, and product release is authorized only after review of all required acceptance records per QMSR 820.70.
