Some Mosaic information can be measured in dollars and some in other units of measure (time, area, etc.). All impacts (benefits and disbenefits) measured in dollars can be compared easily and added to and subtracted from one another, but the values of indicators not measured in dollars are not so easily compared. For example, how would you compare the value of environmental resources to the value of sidewalks or the value of safe routes available in the event of an emergency?
Mosaic addresses questions like these through the use of Multi-Objective Decision Analysis (MODA), a process of structured decision making in which stakeholders assign weights to Mosaic’s categories and indicators. This weight reflects stakeholders’ values in the form of assessment of the relative importance of one indicator as compared with another.
