1. Identify SCEs and performance standards 1.4 Define Operate phase performance standards The performance requirements developed during the first activity (see section 1.1) provides the starting point for refining them into Asset specific Operate phase performance standards. These shall include acceptance criteria that the SCEs must meet and shall be developed in detail to enable the practical verification that all hardware barriers are in place and effective. They are initiated during the Asset’s Define phase and finalised with specific performance requirements and performance assurance tasks during the Execute phase as part of the detailed design. These are the SCE performance standards to be used and maintained during the Asset’s Operate phase. The performance standards should not be confused with either the design specifications required to establish Technical Integrity or the preventive maintenance strategy required for the maintenance of equipment, e.g. lubrication. They specifically cover only the tasks necessary to validate that SCEs perform the function necessary for the barrier to be effective.
