What is Software Quality Assurance?

Software Quality Assurance

“A planned and systematic pattern of all actions necessary to provide adequate confidence that the item or product conforms to established technical requirements.”

IEEE STD 610.12-1990

SQA ensures

• An application is error-free and there is no bug,
• Dependable,
• Fully documented,
• Maintainable down the line,
• Entirely functional according to every specification and requirement.
• Make sure that ordinary people, regular users, will be able to do everything that the application is supposed to empower them to do.

Achieving Software Quality

Definition:

“For a software application to achieve high quality levels, it is necessary to begin upstream and ensure that intermediate deliverable s and work products are also of high quality levels. This means that the entire process of software development must itself be focused on quality”
Capers Jones

From above definition we can conclude that
A high quality software only can be achieved when follow software quality assurance .Which says that start from the root and continue all the process till the end of development of a software. Monitor all the activities and fix the issue as it arises.

what is software quality?
