A User Evaluation of a Decision-Support System: The Community Assessment Model for Odor Dispersion (CAM)
This article is from Journal of Extension 49 (2011): Article# 4FEA7. Posted with permission.
This article introduces to the agricultural Extension community a decision-support system—the Community Assessment Model for Odor Dispersion (CAM)—that is helping Iowa swine producers minimize potential odor conflict. Additionally, we share our rationale and approach to evaluating both CAM and its outreach approach. CAM accounts for local conditions and helps producers assess odor risk from new facilities. Based on a user survey, 75% of producers rated CAM as "useful" to "very useful" in decision-making. Results suggest that CAM has passed the primary test of applied science as measured by usefulness to producers in making better decisions.
