Evidence-Based Management (EBM) has been subject to a number of persuasive critiques in recent years. Concerns have been raised that: EBM over-privileges rationality as a basis for decision-making; 'scientific' evidence is insufficient and incomplete as a basis for management practice; understanding of how EBM actually plays out in practice is limited; and although ideas were originally taken from evidence-based medicine, individual-situated expertise has been forgotten in the transfer. To address these concerns, we adopted an approach of 'opening up' the decision process, the decision-maker and the context (Langley et al., 1995). Our empirical investigation focuses on an EBM decision process involving an operations management problem in a hospital emergency department in Australia. Based on interview and archival research, we describe how an EBM decision process was enacted by a physician manager. We identify the role of 'fit' between the decision-maker and the organisational context in enabling an evidence-based process and develop insights for EBM theory and practice.Keywords: Evidence-based management, context, healthcare management, qualitative methods April L.

IntroductionOver the past decade, there has been increasing interest in developing an evidence-based approach to management decision-making (Pfeffer and Sutton, 2006;Rousseau, 2012;Rousseau, 2006;Tranfield, Denyer and Smart, 2003). Observing how evidence-based practice has enhanced patient care in medicine (Sackett, Rosenberg, Gray, Haynes and Richardson, 1996), leading management scholars argue that decision processes within organisations can be similarly improved by systematic analysis of 'best available evidence' (Pfeffer and Sutton, 2006;Rousseau, 2006). The Oxford Handbook of Evidence-Based Management describes EBM as the "science-informed practice of management", which fundamentally involves "using scientific knowledge to inform the judgment of managers and the process of decision-making in organizations" (Rousseau, 2012, p. xxiii). Advocates of EBM see its potential to help bridge the research-practice gap in organisations through management educators incorporating EBM in their teaching (Casio, 2007;Erez and Grant, 2014;Pfeffer and Sutton, 2007;Rousseau and McCarthy, 2007;Rynes, Bartenuk and Daft, 2001;Rynes, Giluk and Brown, 2007), contributing to the relevance of business schools (Bennis and O'Toole, 2005;Thomas and Wilson, 2011).Other scholars, however, are more cautious of EBM's applicability to management decision-making in practice and offer four particular critiques. First, EBM privileges science and rationality as the basis for decision-making, even though what 'counts' as legitimate evidence in management studies is contested (Arndt and Bigelow, 2009;Learmonth, 2006;Tourish, 2013). Second, given the divergent nature of the management discipline ...
