Problem Structuring Methods
More actions
Problem structuring methods (PSMs) are a group of techniques used to model or to map the nature or structure of a situation or state of affairs that some people want to change.[1] PSMs are usually used by a group of people in collaboration (rather than by a solitary individual) to create a consensus about, or at least to facilitate negotiations about, what needs to change.[2] Some widely adopted PSMs[1] include soft systems methodology,[3] the strategic choice approach,[4] and strategic options development and analysis (SODA).[5]
