3.1.6 Quality Assurance

Software Quality
The extent to which desirable features are incorporated in to software so it can reliably and efficiently continue to meet the needs of users.



Students Learn About:

Quality assurance

  • the need to explicitly define the criteria on which the quality of the product will be judged
  • putting in place management processes to ensure that quality criteria will be met
  • an ongoing process throughout development to ensure the quality criteria will be met

Students Learn To:

  • identify a range of criteria on which the quality of the product will be judged
  • identify relevant processes for a given criterion that will result in a quality product



  • Quality assurance (QA) is a set of processes that occur throughout the development and manufacturing of any type of product. 
  • These QA processes ensure standards and requirements are met and continue to be met such that the final products are of a high quality.
  • Software quality is a measure of the extent to which desirable features, including functional requirements, are included such that the software reliably and efficiently continues to meet the needs of users.
  • Software Quality Assurance (SQA) aims to provide users with confidence in the integrity of software. SQA ensures that software will function reliably as intended and is free of errors and other vulnerabilities. 
    • Vulnerabilities include both intentional and unintentional faults, such as security flaws, inclusion of untested code and of course a variety of other bugs which may result in loss of data or reduced reliability.
