Change Request

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 checkpoint in a governed workflow where an authorized person must review and explicitly approve before the process can proceed to the next stage. Approval gates enforce segregation of duties, ensure that decisions are made by personnel with appropriate authority, and create auditable decision points. Each gate has defined entry criteria, review requirements, and authority levels.

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.
