    EUROCONTROL Network Manager NMDNOM/SAFESP+ Programme ES 2 -WS3-13 SYSTEM SAFETY ANDHUMAN PERFORMANCEWHY THINGS GO RIGHT   “  A SYSTEMS PERSPECTIVE ON PEOPLE AND SAFETY  ”    26 - 27 SEPTEMBER 2013   STILLORGAN PARK HOTEL   DUBLIN  ES2-WS3-13 HUMAN PERFORMANCE – WHY THINGS GO RIGHT Degraded Modes of Operations Degraded modes of interaction reflect the everyday reality of most complex systems where engineers and users find waysof “working around” failures in underlying infrastructures.These routine failures arise from many different causesincluding design flaws in legacy systems, variations in theconfiguration of new applications, from routine stochasticfailures in hardware components, interventions by sub-contractors etc. In this seminar we will explain the implicationsof a culture of coping with degraded modes and explore howdegradations lead to local adaptations. In particular, we willfocus on the human factors of engineering in safety-relatedapplications.  Key questions:   -   How can we cope with everyday failures to maintainlevels of service without undermining system safety? -   Can we develop rapid forms of risk assessment toidentify potential dangers from degraded modes withlimited resources of time and safety-managementexpertise? -   What are the human factors that most influenceinfrastructure engineering and how do they differ fromthe human factors of system operators? Professor Chris Johnson    ES2-WS3-13 HUMAN PERFORMANCE – WHY THINGS GO RIGHT Navigating Seas of Complexity(Trade Offs)  This talk will present the story of complexity, brittleness, andresilience in human systems that perform difficult activitiesunder pressure to be both highly productive and ultra safe.Failure is due to brittle systems, not human error. Systemsoperate successfully due to sources of resilience, usuallyhidden or under appreciated. Explaining accidents byattributing error to one or another component, usually a human,hides the operation of the systemic factors that createbrittleness or resilience. As a result of this and other simplifications, systems are more precarious than appreciatedby stakeholders.Brittleness plagues systems ironically due to new capabilitiesthat increase interdependencies - therefore complexity is thesource of the threats to safety and to organisational viability.The same factors that produce short run improvements add tocomplexity that sets the stage for sudden puzzling collapseswhen, inevitably, events challenge the performanceboundaries inherent in all systems.But surprises, though inevitable and ongoing, are handledregularly as people in various roles step into the breach toovercome adaptive shortfalls and supply extra sources of resilience. In other words, hidden by successful adaptation,people anticipate bottlenecks ahead, act to fill gaps, andforestall failure.Stakeholders miss how their systems are precarious in theface of surprise and how sources of resilience forestall failures  ES2-WS3-13 HUMAN PERFORMANCE – WHY THINGS GO RIGHT because they are trapped in simplifications. The urge tosimplify, linearise, and compartmentalise guaranteesorganisations will miss, hobble, and eliminate the sources of resilience. The way out lies in exploring the factors that endowa system with the ability to outmanoeuvre complexity.The story explains how operations become more brittle andtherefore more risky than any stakeholders desires; howpeople in various roles step into the breach to overcomeadaptive shortfalls and supply extra sources of resilience. Thepatterns of complexity, brittleness and resilience are revealedin how people anticipate bottlenecks ahead, act to fill gaps,and forestall failure. This story provides a deep picture of thegeneral principles and even laws that capture how complexadaptive systems that serve human purposes work.  Key questions:   -   Describe a situation/event where there were hiddensurprises and gaps, where the system was brittle butsomehow something extra was injected to keep going -   How was the event handled? -   How were the gaps bridged? -   Were there hidden interconnections or interdependencies, and how were theynoticed/identified?
