Risk Assessment
The risk management process used in this project is shown in Figure 6.2 below. It is an analysis and problem solving technique designed to provide a logical process for the selection of treatment plans and management actions to protect the community against unacceptable risks. The process is based on the fundamentals of the ISO risk assessment standard ISO 31000:2009. Figure 6.2Risk Management Process – Abridged
IDENTIFY RISKS - What can happen ? - When and why ? - How and why ?
ANALYSE & EVALUATE RISKS - Consequences - Likelihood - Level of Risk - Evaluate
TREAT RISKS - Identify options - Assess options - Treatment plans
The risk assessment process identifies credible risks, the likelihood of the risk event occurring, the consequences should the event occur, develops a risk rating, evaluates the risk and develops a risk treatment plan for nonacceptable risks. An assessment of risks 13 associated with service delivery from infrastructure assets will identify the critical risks that will result in significant loss, ‘financial shock‘ or a reduction in service. Critical risks are those assessed with ‘Very High’ (requiring immediate corrective action) and ‘High’ (requiring corrective action) risk ratings identified in the Infrastructure Risk Management Plan. The residual risk and treatment costs of implementing the selected treatment plan is shown in Table 6.2.It is essential that these critical risks and costs are reported to management.
