Quality Assurance (QA) explained

• To understand quality assurance (QA) and software testing, it is important to know these two concepts chronologically. Quality assurance is the process that is done while the software is in development at every step of the process. 

• Quality assurance (QA) is a comprehensive concept that spans the entirety of the software development process. It encompasses a range of activities with the primary goal of ensuring that the development and delivery processes are efficient and lead to the creation of high-quality software.

• The central focus of quality assurance is on preventing defects rather than solely identifying and rectifying them. The objective is to enhance processes and proactively mitigate issues to prevent their occurrence from the outset. Hence, quality assurance is purely about prevention.

• Key activities within the realm of quality assurance involve continual process improvement, the establishment of standards and guidelines, the execution of audits, and the enforcement of best practices throughout the entire development lifecycle.

• Quality assurance plays a pivotal role throughout the software development process, from the initial planning stages through the final release of the product. Its involvement is not limited to a specific phase but rather extends across the entire lifecycle to ensure the overall quality and efficiency of the software development endeavor.

• Quality assurance encompasses the entire process of software production, as opposed to being focused on one part of the production process like software testing.
