Managing Risks - Towards a Safe and Efficient Society Human Behaviour & Business Aspects Brian Spedding A presentation to the Participants’ Forum at European Research 2002 11th November 2002 3 “The ability to understand, measure and weigh risk is at the heart of modern life” Peter Bernstein, “Against the Gods: The Remarkable Story of Risk” 4 Importance & Issues • Changing trends and features increase complexity, vulnerability and uncertainty • Affect society’s structures and communications, industrial production and peoples' use of new products and technologies • Increases the levels of uncontrolled risk for fundamental functions of society and business life - as a consequence generates increased lack of safety in people's perceptions 5 Importance & Issues • Increasing complexity of technical systems and products makes them more difficult to understand, monitor and control – more vulnerable to internal failures and malfunctions – more vulnerable to external attacks • Recent events demonstrate the need for improved safety and security • Financial losses can be considerable • Hazards in technical systems may result in loss of human lives and environmental pollution 6 Risk Management is a balancing act Propensity to take risks Potential Rewards Balancing behaviour Perceived danger Accidents & hazards 7 Benefits • New business models for extended products and enterprise networks • More efficient use of assets and networking SMEs with larger companies • Prevention of accidents and events causing human losses and affecting human health, environmental pollution and economic losses • Safer and more humane surroundings for the citizens • Improved competitiveness for European industry Human Factors 9 People Processes Hazards Risk 10 Human factors • Measure impact of human factors in risk identification, assessment and management • Assess possible results of improving human factors – improvements in human-technology interaction – addressing skill sets and training needed by operators in different environments, using different systems - both real and simulated Technology Personnel Integration Environment 11 Improved HTI • Safety-relevant changes in psychological work demands – while implementing ICT • Optimising modalities in man-machine interface • Contextual assessment of organisational culture • Integrated assessment of human reliability in probabilistic analyses • Means for promoting transfer of experience and organisational learning 12 Improved HTI • Incorporate qualitative and quantitative evidence – Adopt techniques such as Bayesian Belief Nets and influence diagrams – Use risk-based indicators to follow up the risk during operation. • Link technical and organisational parameters by identifying the key safety barriers to control – Safety barriers assessment – Interview techniques – Identification of a typology of risk – Performance factors of an organisation and assistance in implementing projects Business Aspects 14 Business aspects • Promote effective risk and reliability management – Develop new tools based on strategic decision making, economic risks, statistics – Develop and evaluate new and innovative business models - extend our concept of "value" • Companies moving from giving guarantees to delivering capacity and making life-long availability agreements – Require systematic consideration of reliability and safety in design, operation and maintenance – Robustness and flexibility will reduce risk and uncertainty, and add economic value 15 Cost of risk • Increased exposure to risk is a consequence of: – globalisation of economic activity – mobility of capital flows across national boundaries – widespread privatisation of public sector enterprise (e.g. utilities) – intensified competition – high volatility in international financial markets • Determine which assets are worth protecting, given the cost of doing so – “Cost of risk = insurance premium paid” – self-insurance, administration costs, hedging 16 Examples in business • Private Finance Initiative (PFI) • Asset management • Business continuity planning • Risk-based regulation 17 PFIs • Investment/financing decisions involving allocation of resources under uncertain conditions are associated with some risk – assumed (in the expectation of a higher return) or – transferred to others (through hedging and/or contracting arrangements) • Principles of infrastructure project finance deals (eg PFI) – allocate specific risks to the parties best able to bear them – control performance through incentives – use market hedging instruments (eg derivatives) to cover market-wide risks (eg interest and exchange rate fluctuations) 18 PFI - different risks at different stages • Construction – completion – cost over-run – performance – environmental • Operation – performance – regulatory – environmental – off-take – market 19 PFI - handling the risks • Moves towards fee-based project financing makes risk management of greater importance • Analyse project exposure to risks – – – – – from different perspectives bargaining between stakeholders economic viability Monte Carlo simulation to assess uncertainties variation over time “Optimal Risk Allocation” or “Maximum Risk Transfer” X ? 20 Asset Management • Increasing adoption of ever more complex technology and communication systems – greater dependency on complex technology brings a higher risk of business interruptions due to the failure of some of, or all, the systems and services supporting them – traditional maintenance management pays little attention to managing risk • Asset management – scheduling of maintenance activities - “living with defects” – trade-offs between risks and costs of downtime/disruption 21 Asset Management • Critical equipment/systems should be considered as assets supporting business critical processes • Positive management of these business-critical systems is needed • This enables: – better understanding of complex inter-dependencies, at all levels – management have better control, and flexibility to meet the demands of changing business needs 22 Asset Management • Effective asset management represents one of the main components in the reduction of organisational business risk • The key to effective asset management: – the ability to accurately predict the future performance and associated life cycle costs of assets • Develop an understanding of their current condition and service potential • Then apply advanced asset management techniques to this knowledge base 23 Asset Management • Life Cycle Planning – provides a strategic planning capability to compare projected NPV LCCs of various assets whilst still at the asset planning stage Operating Profile Pre-Operation Tasks % Availability Available Resource Operating Hours Operations Performed No Servicing – maximise ROI – risk analysis, maintenance history and opportunity costs into consideration Failure? Yes Manpower Pool • Asset Renewal Optimisation – optimise renewal options for assets currently in service Post-Operation Tasks Operation Maintenance Tasks Facilities Pool Component Resupply Time Work Shop Tasks Spares Pool Support Equipment Pool Usage Man hours %Utilisation 24 Asset Management • Failure Mode Analysis – Consequences of Failure – Probability of Failure • Valuation Analysis – manage infrastructure valuation requirements – report on asset valuations, depreciation, capital expenditure, disposals, acquisitions etc 25 Business continuity • Turnbull report • From March 2001 companies listed on the London Stock Exchange have been required to make annual governance statements referring to their identification and mitigation of risk • More specifically the report "..places an obligation on listed companies to establish a sound system of internal control and incorporate risk management within their normal management and governance processes." 26 Risk-based Regulations • More flexible than the more traditional rule-based regulations • Risk analyses can help prove that new solutions are acceptable and even safer than traditional ones – but taking into account how people view risks is a challenge • Regulatory authorities able to concentrate efforts on areas were the risk is considered least acceptable, and where the effect in terms of risk reduction is highest • Need high-quality, robust risk analyses Conclusions 28 Conclusions • People are an inescapable part of the risk equation – perception/identification of risk – management of risk – individually and in an organisational context • Business aspects of risk have many ramification – risk allocation – asset management – risk-based regulation • Transnational & cross-sector issues will be key
