Identify SCEs and performance standards Major Hazards are identified during the HEMP and developed into the bow-tie models to show the escalation, consequences and barriers which are required to manage the hazards. All resultant SCEs have their specifications defined to establish integrity during the project and their Operate phase performance standards defined for project handover and subsequent safeguarding of integrity. The end result is a package of approved SCEs identified in the Asset Register with Operate phase performance standards.
