Root Cause Analysis
Root Cause Analysis is a systematic way of solving problems by finding out why something went wrong, rather than just fixing the immediate issue. Think of it like being a detective: instead of just cleaning up water from a leak, you figure out why the pipe broke in the first place. In software and product development, it's used to prevent problems from happening again by understanding their true source. Quality Assurance professionals use this approach to improve product quality, reduce defects, and make processes more reliable. It's sometimes called "RCA" for short, or referred to as "problem root analysis" or "causal factor analysis."
