ESSA has used decision analysis procedures since 1995 to facilitate stakeholder agreement on management actions, to help scientists agree on which uncertainties most critically affect decisions, and to assess the benefits and costs of adaptive management actions.

Decision analysis is a powerful approach to making decisions in the face of significant uncertainty. BC Hydro has recognised this by incorporating a decision analysis approach into the Water Use Planning Process, and has worked with ESSA on a number of projects where decision analysis was used.

ESSA has successfully applied decision analysis to a wide range of multi-stakeholder decision-making processes in many areas of resource management. While a powerful tool in its own right, we have found that the utility of decision analysis is greatly enhanced when used in conjunction with other skills at which ESSA excels, including multi-stakeholder facilitation, experimental design, modelling, and technical analyses.
