Root Cause Analysis
Root Cause Analysis is a structured problem-solving method used to identify the underlying causes of issues, failures, or operational problems.
Also known as: RCA, Cause Analysis, Problem Root Cause Investigation
Full Definition
Root Cause Analysis (RCA) is a systematic process used to identify the primary cause of a problem rather than only addressing its symptoms. It helps organizations understand why issues occur, prevent recurrence, improve operational efficiency, and support continuous improvement initiatives. Root Cause Analysis is widely used in business analysis, quality management, software development, operations, manufacturing, IT service management, and risk management to resolve process failures, defects, incidents, and performance issues effectively.
