What is Quality Assurance

What is Quality Assurance (QA)?

Quality Assurance is a proactive, process-oriented approach focused on preventing defects before they occur. QA defines the standards, guidelines, and processes that the entire team follows during development to ensure quality is built into the product from the start.

Key Characteristics of QA

• Focuses on the process used to build the product, not the product itself.
• Is preventive in nature — it aims to stop defects from being introduced.
• Involves activities like process definition, training, audits, and standards enforcement.
• Is the responsibility of the entire team, not just testers.
• Answers the question: "Are we following the right process to build this correctly?"

Common QA Activities

• Defining coding standards and development guidelines.
• Conducting process audits and reviews.
• Establishing test strategies and quality benchmarks.
• Training team members on best practices.
