Quality management system

The documented organizational structure, procedures, and controls used to ensure products and services consistently meet requirements and are continually improved.

Related: Corrective and preventive action, Design controls
Corrective and preventive action

A formal process for investigating root causes of detected problems, implementing fixes, and preventing recurrence, with documented verification of effectiveness.

Related: Root cause analysis, Quality management system
Design controls

A set of planned design and development activities, including requirements, reviews, verification, validation, and change control, applied to ensure a device meets user needs and specifications.

Related: Quality management system, Human factors engineering
Human factors engineering

The discipline of designing devices and workflows around real human capabilities and limits, reducing use errors through usability testing, clear displays, and mistake-proofing.

Related: Use error, Failure mode and effects analysis
Use error

An unintended outcome arising from the interaction between a user and a device, often caused by confusing design rather than negligence, and addressed through redesign or training.

Related: Human factors engineering, Root cause analysis
Failure mode and effects analysis

A prospective team method that lists how a process or device could fail, rates severity, likelihood, and detectability, and prioritizes actions to reduce the highest-risk failures.
