Software Quality Assurance (SQA) is a systematic process that ensures software meets quality standards. It is essential for delivering reliable, secure, and efficient software products.

What is Software Quality Assurance?

Software Quality Assurance (SQA) involves a set of activities designed to improve and ensure the quality of software. It encompasses the entire software development lifecycle, from requirements gathering to maintenance. SQA aims to prevent defects by implementing rigorous testing and quality control measures. This ensures that the final product meets the required standards and functions as intended.

Types of Software Quality Assurance

1. Process Quality Assurance

This type involves evaluating and improving the software development process. It ensures that all processes are followed correctly to prevent defects.

2. Product Quality Assurance

Focuses on the final product, ensuring it meets the specified requirements and standards. This includes various testing methods like unit testing, integration testing, and system testing.

3. Internal Quality Assurance

Conducted by the development team, this type ensures that internal standards and guidelines are consistently followed during the development process.

4. External Quality Assurance

Performed by an independent team or third party, this ensures that the product meets external standards and client requirements.

Benefits of Software Quality Assurance
