Understanding the Processes Involved in Software Quality Assurance and Its Benefits

Software Quality Assurance, also referred to as application quality assurance is a procedure designed to make sure that a developed application or software meets the standardized or defined quality requirements. Software quality assurance is a continuous process throughout the development cycle of an application and checks each development phase to ascertain that the desired quality measures are met.

Rather than checking the quality upon completion of the software development process, application quality assurance routinely monitors the software at each development stage. The software development process can only progress to the next phase after the stipulated quality measures have been met. This goes on until the completion of the software.

Common industry quality standards include the capability maturity model integration (CMMI) and the ISO 9001:2000 overseen by the Council of Canadian quality assurance. The body is in charge of accrediting service and product certification bodies that oversee third-party appraisals. Software quality assurance is focussed on identifying and fixing problems with the software development process before they evolve into major issues. The two principal components of software quality assurance are software testing and system integration testing (SIT).

Software Testing

Also known as application testing, software testing constitutes a number of interlinked processes intended to investigate, evaluate and ascertain the quality and completeness of an application. The purpose of software testing is to make sure that the software product complies with industry standards vis-à-vis functional, technical, business, regulatory, and end-user requirements. Application testing checks and examines the software through various testing processes.

The key functions of application testing include:

• Assessing installation, compatibility, localization, security, performance, and usability.
• Making sure that the application is error free via the identification and elimination technical errors and bugs.
• To verify application completeness in accordance with its business or functional requirements.

Some of the major software tests include black box, white box, and grey box testing. The application must pass all these tests to be considered fit for the end user.

System Integration Testing (SIT)

System integration testing is an advanced application testing process that verifies the successful integration of all the subcomponents of a system. SIT seeks to establish if the software can coordinate with other systems in the environment while maintaining data integrity. System integration testing is done before validation testing and before unit testing. SIT testing is a tedious process since it examines automation of all the associated components of an application and the dependencies that exist between them.

Advantages of Software Quality Assurance

• Software quality assurance ensures the creation of a mature software development process.
• Testing the quality of a software guarantees the creation of a complete, high-quality product.
• It corrects errors that would otherwise be a lot more expensive to correct if they passed the initial development stages.
• Improves the entire software development process.
