This study explores the use of strategy maps for decision-making in complex settings. Specifically, this study draws on complexity as a conceptual lens to qualify the contexts in which companies operate, suggesting that management control systems should act as support systems in these contexts. Using data collected from a in depth case study, this paper finds that strategy map, as a peculiar form of visual representation, helps top management to rationalize, share and generate new insights about the roles of management control systems in complex settings.
