Regulations
Business Context
Demonstrating compliance with Safety Integrity Level (SIL) requirements
requires detailed calculations, validation, documentation, testing, and
periodic reassessment. These activities improve confidence in system
performance but demand significant engineering effort.
The Contradiction
More rigorous SIL verification improves confidence in functional safety.
More verification requires additional engineering resources.
Why It Exists
Every Safety Instrumented Function must be evaluated throughout its
lifecycle, creating substantial engineering workload in facilities with
numerous protective functions.
Direction
Standardize SIL verification methodologies, automate engineering
calculations where appropriate, and prioritize engineering effort
according to process risk and system criticality.
