DSS Step 6: Selection of the best solutions

In Step 6 the selection of the best solution (sets of measures) takes place. In dialogue with the main stakeholder groups (pointed out in

Step 0

; System definition) the most applicable selection method is chosen based on the expected effects of the measure (sets). With this method the measures and their effects are weighed (and ranked). For those cases where only costs and concentration reduction are important Cost Effectiveness Analysis (CEA) has to be performed. If besides costs and concentration reduction also other effects are relevant a Societal Cost Benefit Analysis (SCBA) or a Multi-criteria Analysis (MCA) has to be performed. From the result of these analyses the best solutions are selected in dialogue with/or advice from the main stakeholder groups.

Framework of the step
In Step 6 tools and guidelines will be given to come to the selection of the best solution (sets of measures). In dialogue with the main stakeholder groups (pointed out in Step 0) the most applicable selection method is chosen based on the effects of the measure (sets). This stakeholder involvement is very important as they have to agree on the starting points the applied methods, weighing factors etc.
For those cases where only costs and concentration reduction are considered to be relevant Cost Effectiveness Analysis has to be performed. If besides costs and reduction of concentration also other effects are relevant a quick scan Social Cost Benefit Analysis or Multi-criteria Analysis has to be performed. With this method the measures and their effects are weighed.
From the result of these analyses the best solutions are selected in dialogue with/with advice from the main stakeholder groups.

Instructions how to do it
Basically Step 6 is carried out as depicted in the figure below.

Result of the step
Based on the results of the analysis with the applicable selection method the best solutions (measure option or sets of measures options) are selected in dialogue with/with advice from the main stakeholder groups. Section 4.2.2 provides a worked out example of a result of Step 6.
