Quality Control

Quality control (QC) is a systematic process for ensuring that products or services meet specified requirements. QC involves inspection, testing, and monitoring of processes. The PDCA cycle (Plan-Do-Check-Act) is a continuous improvement framework. Quality assurance (QA) focuses on preventing defects, while QC focuses on detecting defects. Statistical quality control (SQC) uses statistical methods to monitor and improve quality.
