SOFTWARE QUALITY ASSURANCE (SQA) is a set of activities for ensuring quality in software engineering processes (that ultimately result in the quality of software products).
It includes the following activities:
- Process definition and implementation
- Software Development Methodology
- Project Management
- Configuration Management
- Requirements Development/Management
- Software Design
- identifying weaknesses in the processes
- correcting those weaknesses to continually improve the processes
The quality management system under which the software system is created is normally based on one or more of the following models/standards:
- Six Sigma
- ISO 9000
Note: There are many other models/standards for quality management but the ones mentioned above are the most popular.
Software Quality Assurance encompasses the entire software development lifecycle and the goal is to ensure that the development and/or maintenance processes are continuously improved to produce products that meet specifications/requirements.
The process of Software Quality Control (SQC) is also governed by Software Quality Assurance (SQA). Read Differences between Software Quality Assurance and Software Quality Control
SQA is generally shortened to just QA.
