What is the difference between quality assurance (QA) and qualilty control (QC)?
Many people have asked me about the difference between Quality Assurance and Quality Control. Here is the summary:
ISO 9000 Definitions
- What: The activities or techniques used to achieve and maintain the product quality, process and service.
- How: Finding & eliminating causes of quality problems through tools & equipment, so that customer’s requirements are continually met.
- What: Prevention of quality problems through planned and systematic activities including documentation.
- How: Establish a good quality management system and the assessment of its adequacy & conformance audit of the operating system & the review of the system itself.
