Software Quality
There is no fixed definition of software quality. It can be defined in many ways. From a user point of view
– A software is of good quality if it fulfils all requirements.
– A software is of good quality if a user is satisfied he or she not facing any difficulty during its use.
– A Software quality is just related to level of satisfaction of it’s user.
Here the goal is to achieve high-quality software product, Software quality can be defined as –
“Conformance to explicitly stated functional and performance , requirements, explicitly documented development standards, and implicit characteristics that expected of al professional developed software.”

Three import points for quality measurement:
- Use requirements as the foundation.
- Use specified standards as the criteria.
- Considering implicit requirements
Software Quality Assurance
” Software Quality Assurance enforce the standards and techniques that improve the quality of development process “
Some Facts About quality assurance
- The first formal quality assurance and control function was introduced at Bell Labs in 1916 in the manufacturing world.
- During the 1950s and 1960s, the programmers controls their product quality.
- During the 1970s, quality assurance standards were introduced first in military contract software development.
Now a question comes in mind that Who involves in quality assurance activities and what are these activities ?
So the answer is Software engineers, project managers, customers, sale people, SQA group Engineers involved the quality assurance activities like –
- apply technical methods and measures
- conduct formal technical review
- perform well-planned software testing
The SQA group’s role serves as the customer’s in-house representative assist the software engineering team in achieving high-quality.
The SQA group’s responsibility:
- Quality assurance planning oversight, record keeping, analysis and reporting The SQA group’s tasks:
- Prepare a SQA plan for a project.
- Participate in the development of the project’s software process description.
- Review engineering activities to verify compliance with the defined process.
- Audits designated software work products to verify compliance the defined process.
- Ensure the deviations in software work and products according to a documented procedure.
- Records any noncompliance and reports to senior management
