Approval Gate

A predefined hierarchy of responsibility that determines who is notified and in what order when an issue exceeds the authority or capability of the current handler. Escalation chains ensure that critical issues receive attention from increasingly senior or specialized personnel, with defined time limits for response at each level.

A systematic process for evaluating, approving, implementing, and documenting changes to process equipment, technology, procedures, or organizational structure that could affect safety, health, environment, or operations. MOC ensures that all changes are reviewed for potential hazards, that appropriate safeguards are implemented, and that affected personnel are informed and trained before the change is implemented.

A discrete, auditable event in the lifecycle of a governed artifact (asset, risk, MOC, inspection) that records a decision, approval, status change, or significant action. Governance events capture who did what, when, why, and with what authorization. They form the backbone of the audit trail and provide the evidence chain for regulatory compliance.

A chronological record of system activities, decisions, and data changes that provides documentary evidence of the sequence of events that have affected a specific operation, procedure, or artifact. In asset integrity management, the audit trail records who made what change, when, why, and with what authorization, creating an unbroken chain of evidence for regulatory compliance and forensic investigation.
