Diagnostic Coverage vs Lifecycle Cost
Calibrate diagnostic investment to equipment criticality and required risk-reduction level rather than applying uniform coverage across all instruments.

Regulations
Business Context
Advanced diagnostics detect hidden failures before they compromise
Safety Instrumented Functions. Increasing diagnostic capability,
however, requires more sophisticated devices, engineering support, and
lifecycle investment.
The Contradiction
Greater diagnostic coverage improves system reliability.
Greater diagnostic capability increases lifecycle cost.
Why It Exists
High-performance diagnostic technologies require additional hardware,
software, configuration, validation, and maintenance throughout the
operational life of the system.
Direction
Implement advanced diagnostics according to equipment criticality and
required risk reduction instead of applying the same level of
diagnostics to every instrument.
