We all make mistakes: Human factors and preventive risk management

Kamal Fernando Memorial Lecture Institution of Engineers Sri Lanka, NSW chapter

Dr Annalisa Contos

Human error is often cited as root cause of incidents and accidents. In this talk Dr Contos introduces
key topics within the field of human factors. The talk addresses the environmental, organisational and
job factors as well as human and individual characteristics, which influence behaviour at work in a way
which can affect health and safety. Drawing from examples in the water industry Dr Contos discusses
how human factors are important to both process and product safety.

Threat Consequence (Bow-tie) Diagrams

Information Sheet

This information sheet explains how threat-consequence or bow-tie diagrams can be used for visual risk analysis. Bow tie diagrams describe the pathways of a risk from its cause to its consequence and illustrate the barriers in place to reduce the risk (ISO/IEC 31010, 2009). The strength of bow-tie diagrams is that it goes beyond the usual risk assessment ‘snapshot’ and highlights the links between the threat, its consequences, the barriers preventing the consequence from occurring and the strengths of these barriers. In its full application it can be used to demonstrate the linkages between the barriers and the underlying management system. The highly visual nature of the diagrams are well-suited to communicating risk issues to non-specialists.

Human Factors and Preventive Risk Management in the Water Industry

Ozwater 2015

Dr Annalisa Contos, Jessica Circosta

Although human factors have been shown to be the origin of many accidents in the water industry, they are rarely formally recognised in their approaches to water quality risk management. This paper, present by Dr Annalisa Contos at Ozwater 2015 provides a discussion for as to why human factors are not considered, which industries do recognise them and how this can be and should be incorporated into the water industry.


Towards Effective Corporate Governance from Source to Endpoint

AWA Water Journal September 2014

A Davison, B Burford, A Contos

This paper expands on the duties of directors and overarching corporate governance management for statutory owned corporations (SOCs) in the context of risk management. SOCs need to fully understand their operating context if they are to holistically understand and manage risks. The ‘Frameworks’ within contemporary Australian water cycle guidance, such as the Australian Drinking Water Guidelines, note that enterprises must understand their water ‘products’ from catchment to consumer to ensure that risks are properly identified and managed.

We suggest that an expanded Framework approach from source to endpoint (S2E) could be used to help SOCs identify, understand and manage the risks to all the products and services that they deliver and hence provide for an improved approach to corporate governance. To help illustrate this point, we include information from a recent high profile case, The Hasties Group, which helps to provide clarification on the responsibilities of management and directors including the information that should be sought from management by directors and when.
