Metaphors, Stories, Models: A Unified Account of Decisions.Johannes M. Lehner -2002 -Philosophy of Management 2 (2):11-20.detailsPart 1 of this paper1 used the notions of equivocality and uncertainty to distinguish the situations in which managers make judgements and decisions and described in general how managers use models in these different contexts. This final second part describes in detail the three types of models managers use: formal models, stories and metaphors. It offers five propositions about how managers use the three types of model, propositions which can usefully form the basis of future empirical research.
