Quality assurance
vs. Quality Control

Quality is a key factor in the success of any product or service. To ensure high quality, organizations rely on two main practices: Quality Assurance (QA) and Quality Control (QC). While both are essential for maintaining standards, they serve different purposes and are applied at different stages of the production process.

quality assurance vs quality control

What is Quality Assurance (QA)?

Quality Assurance (QA) is all about making sure things are done the right way from the start. It focuses on preventing problems by setting up good processes.

Key Parts of QA:

  • Planning: Creating strong processes to avoid mistakes.
  • Documentation: Keeping detailed records of how things are done.
  • Auditing: Checking regularly to make sure everyone follows the processes.
  • Training: Teaching employees about quality standards.

History of QA: In the 1980s, ISO 9001-87 set the standard for Quality Assurance. This required organizations to have detailed design plans and specifications. Over the years, these standards have been updated to keep up with new practices.
