A failure-analysis is a systematic methodology for identifying, investigating, and characterizing the root causes and failure mechanisms of components or systems after a failure event. Its parameters are: (1) a failure event is observed, (2) evidence is collected (physical artifacts, logs, operational data), (3) causal chains are reconstructed using structured techniques (fault tree analysis, 5-whys, fishbone diagrams), and (4) findings are documented in a report that informs corrective action. Persistence mechanism: documented procedures and institutional knowledge embedded in engineering practice and organizational learning.

Definition
Why it is in scope
A human-made methodology in reliability engineering for systematically identifying, investigating, and characterizing the causes and mechanisms of component or system failures. Built to persist through documented procedures, forensic techniques, and institutional memory in engineering practice.

Failure analysis is systematically conducted for the sake of improving reliability — identifying failure modes, root causes, and mitigation strategies directly feeds reliability improvement loops. Per Law 8d, the servant (failure analysis) points at the master (reliability).

A fault-tree analysis IS a specific kind of failure analysis — a top-down, deductive method for identifying combinations of component failures that lead to a system-level failure. A competent speaker would call it 'a type of failure analysis.' Direction: specific→general. Nearest kind: failure-analysis (Law 9, Law 11e).

A hazard-and-operability study IS a specific kind of failure analysis — a structured methodology for systematically identifying potential failures, hazards, and operability deviations in industrial processes using guide words and process parameters. Direction: specific methodology → general category.
