The level of risk is usually defined as a combination of likelihood and consequence. When the levels of
risk or likely outcomes do not justify a detailed numerical analysis, qualitative methods are used. This qualitative method is of greater merit if the determination of risk is shared across a range of people from
varying backgrounds and interests. This is usually conducted in a workshop environment. A ranking
system is often used, and this can be best obtained by use of a skilled facilitator. The outcome of this
phase is a list of prioritised risks for further action.
Risk analyses are not always directed to a negative outcome. They can identify and assist in the priority
assignment of opportunities.
The current ranking was undertaken by GHD in accordance with previous experience in biosolids
management projects. As the biosolids management practices adopted are implemented and evolve,
MWCI will need to update the risks identified and re-assess the ranking.
