Quality Assurance vs. Quality Control — Do you know the difference?
Many organizations use QA and QC interchangeably, but they serve different purposes in a quality management system.
🔹 Quality Assurance (QA) → Prevents problems by improving processes, systems, standards, and controls.
🔹 Quality Control (QC) → Detects problems through inspection, testing, measurement, and defect analysis.
Think of it this way:
QA asks: “How can we prevent the defect?”
QC asks: “Does the product meet the requirement?”
When QA and QC work together, organizations can build stronger processes, reduce defects, improve consistency, and deliver greater customer satisfaction.
📌 Quality is not an accident. It’s a system.
