This presentation focuses on managing safety in performance-based systems, highlighting the importance of outcome-oriented approaches and addressing specific safety concerns. It discusses the underlying paradigm of rule-based systems and the inefficiencies and perversity associated with it. The presentation also covers navigational aids for managing safety, including predictive, reactive, and proactive systems. It concludes by introducing the emerging paradigm of performance-based safety and the ABC approach to safety management.

Managing Safety in Performance-Based Systems Captain Dan Maurino Flight Safety and Human Factors – ICAO Worldwide Symposium on Performance of the Air Navigation System Montreal 26 – 30 March 2007
Forensic Safety Management • Focus on outcomes • Unsafe acts at the tip of the arrow • Blame & punishment for failure to “perform safely” • Address specific safety concern exclusively
The Underlying Paradigm–Rule-based System Deterministic – The world as it should be • Aviation system – as pre-specified – is perfect • Compliance based • Outcome oriented • Accident/serious incident investigation
Inefficiency and Perversity The beatings will continue until morale improves 2. Punishment 1. Exhortations to professionalism and discipline 3. Remedial Training 4. Add more procedures & regulations

The Navigational Aids • Predictivesystems • Electronic safety data acquisition systems • Direct observation safety data acquisition systems • Reactive systems • Accident investigation • Incident investigation • Proactive systems • Mandatory reporting systems • Confidential reporting systems • Voluntaryself-reportingsystems

Emerging Paradigm–Performance-Based System Deterministic – The world as it should be • Aviation system – as pre-specified – is perfect • Compliance based • Outcome oriented • Accident/serious incident investigation Ecological – The world as it is • Aviation system – as pre-specified – is imperfect • Performance based • Process oriented • Safety data captured from daily, normal operations
Performance-Based Safety: The ABC • Senior management’s commitment to the management of safety • Initial analysis of system design and risk controls (safety risk management) • Continuous safety monitoring and analysis of safety data from normal operations (safety assurance)
