Multicriteria mapping as a problem structuring method for project front-ending

Despite high uncertainties, strongly diverging values, and often-perverse effects of powerful vested interests, large and complex projects require clear decisions to be made from the outset. Coburn and Stirling introduce multicriteria mapping (MCM) as a problem structuring method for addressing these challenges in project appraisal by engaging with key stakeholders, broadening out the scope of the project, and opening up alternative possible interpretations concerning how to proceed. From defining project goals through to analysing results, two case studies illustrate the MCM process. The resulting interlinked quantitative and qualitative information provides a broader and deeper picture than is usual. Clearly highlighting how different conditions hold contrasting practical implications for action, MCM offers a more robust basis for making decisions under circumstances of uncertainty and complexity.
