Quality Assurance (QA)

What is Quality Assurance (QA)?

Quality Assurance is the broad discipline of building quality into software rather than merely inspecting for it at the end. It spans processes, standards, reviews, and testing aimed at preventing defects across the whole development lifecycle, not just catching them late. QA engineers design test strategies, automate coverage, analyze failures, and advocate for quality across the team. Effective QA leans on fast, reliable automation for repetitive verification—so people can focus on strategy, exploration, and the judgment calls that tools can't make.
