Software Quality Assurance & Testing Fundamentals

Software Quality: Definitions & QA vs QC

  • Quality: The degree to which software meets specified requirements and customer expectations.

  • Quality Assurance (QA): A preventive, process-oriented activity that ensures quality in the processes by which products are developed.

  • Quality Control (QC): A corrective, product-oriented activity that involves identifying defects in actual products using inspections and testing.
