“And now for something completely different” Terry Kelly SSECC January 27, 2006
In the beginning – “the list” • acceptable level of risk • ‘accountable executive’ • confused use of definitions • fuzzy thinking (as opposed to fuzzy logic) • human factors • non-punitive reporting • performance-based approach • quality management “versus” safety management • regulating an SMS • safety culture • safety measurement • target levels of safety • tools to measure safety
The Short List • Performance-based approach • Regulating an SMS • Safety measurement
SMS Defined • “A systematic, explicit and comprehensive process for the management of safety-risks that integrates operations and technical systems with financial and human resource management …”. - TP13881 (2002)

Performance-based • Variation in meaning & understanding • Prerequisites • Evolution from performance-based to process-based
Regulating an SMS • Focus is on compliance • Need measures of compliance • Management systems that are process-driven become process-based
Safety Measurement • Mired in our past best practices • Events —> lagging, descriptive • Misapplication of quality and risk assessment processes • Require explicit and appropriate measures of safety performance
Summary: Current Programs • They do not account for current understanding of accident causation • They are not adequate for current prevention initiatives (e.g. SMS) • A known problem (by some): but not being addressed (seriously) by most • Measurement attention is on technical fixes (new and more software, new and more databases), not on essential determination of what needs to be measured
