Measurable product or process characteristics that have the highest impact on customer requirements.
CTQs translate customer expectations into concrete controls that production and inspection teams can execute consistently.
Clear CTQ definitions keep teams focused on what matters most for acceptance and performance.
Defining CTQs
CTQs should be specific, measurable, and tied to clear limits, methods, and ownership.
Examples include key dimensions, safety attributes, labeling requirements, and performance thresholds.
From requirement to control
Once defined, CTQs must appear in control plans, work instructions, and inspection templates.
Escalation paths should be explicit when CTQ checks fail or trend toward risk.
Key takeaways
- CTQs focus teams on the characteristics that drive customer acceptance.
- They require clear limits, methods, and escalation rules.
- Digital workflows make CTQ compliance easier to enforce.
