- Quality Objective
- A specific, measurable target an organization sets to achieve a defined level of quality β for example, reducing defect rate to below 0.5% within two production quarters.
- Non-Conformance
- Any output, process, or condition that fails to meet a specified requirement or acceptance criterion.
- CAPA (Corrective and Preventive Action)
- A structured process for identifying the root cause of a non-conformance, correcting it, and implementing controls to prevent recurrence.
- Quality Assurance (QA)
- Process-focused activities designed to ensure that quality requirements will be met before or during production β as opposed to inspecting output after the fact.
- Quality Control (QC)
- Inspection and testing activities applied to completed outputs to verify they meet defined acceptance criteria.
- ISO 9001
- The international standard specifying requirements for a quality management system, widely used as a benchmark for customer and regulatory assurance.
- Process Control
- The use of defined procedures, work instructions, and monitoring points to keep a production or service process within acceptable performance limits.
- Acceptance Criteria
- The minimum measurable conditions an output must satisfy to be approved β for example, dimensional tolerances, test pass rates, or defect thresholds.
- Root Cause Analysis
- A structured investigation method β such as 5 Whys or fishbone diagrams β used to identify the underlying cause of a defect or failure rather than just its symptoms.
- Continuous Improvement
- An ongoing commitment to incremental process enhancements, typically formalized through a PDCA (Plan-Do-Check-Act) cycle.
- Document Control
- The process of managing the creation, approval, versioning, distribution, and retirement of quality-related documents to ensure only current versions are in use.
