Evidence-based management (EBMgt) is an emerging movement to explicitly use the current, best evidence in management and decision-making. Its roots are in empiricism as seen in evidence-based-practice, aiming to apply scientific method to evaluating practice.
Evidence-based management entails managerial decisions and organizational practices informed by the best available evidence. As with other evidence-based practice, this is based on the three principles of: 1) published peer-reviewed (often in management or social science journals) research evidence that bears on whether and why a particular management practice works; 2) judgement and experience from contextual management practice, to understand the organization and interpersonal dynamics in a situation and determine the risks and benefits of available actions; and 3) the preferences and values of those affected.
While, like its counterparts in medicine, and education EBMgt considers the circumstances and ethical concerns managerial decisions involve, it tends not to make extensive use of behavioral science relevant to effective management practice.
An important part of EBMgt is educating current and future managers in evidence-based practices. The EBMgt website maintained at Stanford University provides a repository of syllabi, cases, and tools that can inform the teaching of evidence-based management.
Efforts to promote EBMgt face greater challenges than have other evidence-based initiatives. In medicine there is more consensus as to what constitutes best evidence than in the social sciences more generally, and management in particular. Unlike medicine, nursing, education, and law enforcement, "Management" is not a profession. There are no established legal or cultural requirements regarding education or knowledge for an individual to become a manager. Managers have diverse disciplinary backgrounds. A college degree may be required for an MBA - but not to be a manager. No formal body of shared knowledge characterizes managers, making it unlikely that peer pressure will be exerted to promote use of evidence by any manager who refuses to do so. Little shared language or terminology exists, making it difficult for managers to hold discussions of evidence or evidence-based practices. For this reason, the adoption of evidence-based practices is likely to be organization-specific, where leaders take the initiative to build an evidence-based culture. Practices an evidence-based organizational culture employs include systematic accumulation and analysis of data gathered on the organization and its functioning, problem-based reading and discussion of research summaries by managers and staff, and the making of organizational decisions informed by both best available research and organizational information. Organizations successfully pursuing evidence-based management typically go through cycles of experimentation and redesign of their practices to create an evidence-based culture consistent with their values and mission.
Although some advocates of EBMgt argue that it is more likely to be adopted in knowledge-intensive organizations, recent research at the University of Oxford into six leading organizations in the healthcare industry found that managers and clinical leaders used a variety of forms of knowledge, drawing on academic research, experiential knowledge and respected colleagues. The researchers concluded that skilful 'knowledge leadership' is crucial in translating EBMgt and other academic research into practice in ways that are relevant and can be mobilized in specific organizational contexts.
Organizations adopting agile approaches in their product development, often find they need to make changes in other areas to reap the full benefits of the changes (the growing field of business agility and agile transformation). Evidence-based management provides a more structured approach to working through such change in short-cycles; to focus investments in areas that will bring the greatest value soonest; and to provide a framework for evaluating their success.
The weak form alternatives to evidence-based anything include hearsay, opinion, rhetoric, discourse, advice (opinion), self deception, bias, belief, fallacy, or advocacy. The stronger forms include concerns about what counts as evidence, types of evidence, what evidence is available, sought or possible, who decides and pays for what evidence to be collected, and that evidence needs to be interpreted. Also there are the limitations to empiricism as well argued in the historical debate between empiricism and rationalism which is usually assumed to be resolved by Immanuel Kant by saying the two are inextricably interwoven. We reason what evidence is fair and what the evidence means (Critique of Practical Reason).Critical theorists have raised objections to the claims made by those promoting evidence-based management. In particular, EBMgt has been criticised for treating "evidence" and "scientific method" as if they were neutral, value-free descriptions. From this perspective, what counts as "evidence" is considered as intrinsically problematic and contested because there are different ways of looking at social problems. Furthermore, in line with perspectives from critical management studies, "management" is not necessarily an automatic good thing--it often involves the exercise of power and the exploitation of others. Efforts have been made, however, to include a balanced treatment of such issues in reviewing and interpreting the research literature for practice. Criticisms persist, and critical theorists say fundamental problems with evidence-based management have been ignored.
One potential alternative to the evidence-based approach is use of dialectic, argument, or public debate (argument is not to be confused with advocacy or quarreling). Aristotle in works like Rhetoric, reasons that the way to test knowledge claims was to set up an inquiry method where a sceptical audience was encouraged to question evidence and its assumptions. To win an argument, convincing evidence is required. Calls for argumentative inquiry, or the argumentative turn may be fairer, safer and more creative than calls for evidence-based approaches.
Some of the publications in this area are Evidence-Based Management, Harvard Business Review, and Hard Facts, Dangerous Half-Truths and Total Nonsense: Profiting From Evidence-Based Management. Some of the people conducting research on the effects of evidence-based management are Jeffrey Pfeffer, Robert I. Sutton, and Tracy Allison Altman. Pfeffer and Sutton also have a website dedicated to EBMgt.
Evidence-based management is also being applied in specific industries and professions, including software development. Other areas are crime prevention (Sherman et al. (2002), public management, and manufacturing.
