Root cause analysis (RCA) is a systematic accessach used by by ameners to o identify thee credital causes of problems or failures in systems and processes. Advance d metods enhance thee preciacy and accessionof RCA, enabling better decision- making and problem resolution.

Fishbone Diagram (Ishikawa Diagram)

Te Fishbone Diagram is a vizual tool that helps identifify potential causes of a problem. It categorizes causes into groups such as people, processes, equipment, and materials. Engineers use this methodd during brainstorming sessions to objevite all possible factors contriling to an issue.

Fault Tree Analysis (FTA)

Fault Tree Analysis is a deductive, top-down accach that models thee patways lealing to a system failure. It uses logic symbols to gott events and their accessivows, helping featers identifify root causes and assess thes probability of fafures.

Both Fishbone and Fault Tree Analysis are valuable tools in RCA. Te Fishbone Diagram is more suable for brainstorming and initial cause de identication, while Fault Tree Analysis provides a detailed, quantitative assessment of failure patways. Combing these methods can imprope problem- solving effectiveness.
