Niklas Luhmann, one of the most influential sociologists of the 20th century and father of social systems theory, once stated that organizations are made of decisions (Luhmann 2000). He even went further and argued that every decision taken builds on past decisions which accumulate to an organization’s future. On a more practical level, making the right decision can be a matter of life and death in high-risk environments such as aviation, medicine, or the military. In business, management and organizations, decision-making quality is a key determinant of good performance. We will take a look at the state of decision-making in the business sector and how Evidence-based Management can help managers, professionals and other stakeholders to improve decision-making quality.
As a manager and professional, decision-making is daily business
Particularly for managers and professionals, decision-making is daily business. Day in and day out they are confronted with various types of decisions ranging from small ones, such as when to schedule meetings, to strategic ones, such as when to launch a new product into the market. There is an unspoken consensus and convictions that most, if not all the time, the intuition-based decision-making approach leads to high-quality outcomes. This makes them proud of their decision-making skills and also meets the implicit expectation of their followers, team memebers and coworkers, which require them to be competent and decisive (Hogan und Kaiser 2005).
When somebody asks managers or professionals why they think their decisions are the right ones, more often than not they relate to year-long experience, education and the knowledge accumulated during professional life. But this is not all. In addition, you will hear the argument that knowledge is kept up-to-date by reading business books and CEO biographies on how to solve tricky business problems and become a successful manager. On top of this, many of them participate in internal and external training programs led by consultants and gurus, who promise to teach how to develop the organization to the next level by following the most recent management trends and models. Isn’t that more than enough to show that managers and professionals make the right decisions?
The 'Evidence Movement' targets at increasing decision-making quality in medicine, law enforcement and management
These questions were the starting point of the so called 'Evidence Movement', which has its origin in the healthcare sector and since then has reached many other areas, notably also including management (Baba und HakemZadeh 2012). The driving force behind evidence-based practices is the increasing awareness that human decision-making is prone to bias and failure, which in turn leads to poor outcomes. This is especially true in high-risk areas such as the healthcare sector, where poor decisions can be a matter of life and death. However, it is not just healthcare where poor decisions and as a result human error can have a catastrophic impact (Strauch 2016). Day in and day out, managers and professionals and other stakeholders make decisions that shape the future of our organizations. Evidence-based Management (EBM) targets at helping us to improve decision-making quality.
Why do we need EBM in business? There are more than 200 different biases that affect decision-making quality
Looking at recent insights from research and science unveils that the traditional and intuition-based decision-making approach mentioned above leads to poor outcomes. One of the key factors that undermines our decision-making performance is bias. In one of the first attempts to structure the more than 200 biases that describe how we are influenced by others, context and ourselves, Spetzler (2016) identified six different bias categories:
Protection of mindset
Personality and habits
As a practitioner, of course it is not required to know all those biases in detail. However, it definitely would help to be aware that decision-making behavior is not as rational and straightforward as we might think. It would be even more beneficial to know that there are different bias categories that describe how we unconsciously tweak our decision-making behaviour in the one or other (undesirable) direction.

A considerable amount of information we are exposed to is of questionable quality
Another factor that impacts decision-making quality is the information or evidence utilized to make decisions. Most of us tend to believe that the information we are exposed to throughout the day is valid and “true”. Scrutinizing the business books, newspaper articles, social media posts and consultancy white papers etc. in more detail reveals that most of them don’t live up to basic quality standards as for instance are used in scientific research. Beyond that, most business professionals don’t read scientific journals (Rynes et al. 2002) because they are hard to read and many of them are still hidden behind paywalls.
When we cannot solely rely on the popular business literature, why not use the internet to search for relevant information? While there is a huge amount of relevant content created every day, it strongly depends on where you look for it and who wrote it for whom. Many articles, blog posts and website target at selling the most recent management trends they think are required to increase organizational performance (and make money out of it). This is why it is always good advice to question when easy answers are given in response to complex problems. Critical thinking is one of the key skills needed to cope with the increasing amount of information available.
Stress and cognitive overload undermines decision-making quality
Finally, there are factors like stress and cognitive overload that impact the way decisions are made on all levels. Those factors weigh heavily on decision-making quality when times get tough and when the pressure to deliver results increases. For instance, stress and a lack of sleep is a combination that many business professionals face on a regular basis, that has a significantly negative impact on ability to make high-quality decisions (Larsen 2009). This effect is reinforced when the situation involves a high-level of decision complexity, which draws on cognitive resources (Dobbins und Han 2009).
Evidence-based Management is an approach that helps to increase decision making quality
Evidence-based Management doesn’t provide answers to specific business problems. This also makes Evidence-based Management different to many of the management trends and fads that promise to solve business problems by following recipes like pre-determined models or organizational interventions. Instead, Evidence-based Management is an approach that helps us to reflect on how we make decisions and gives guidance on how to improve our decision-making quality.
How does Evidence-based Management work? It encourages us to use a structured decision-making process
Everything starts with an understanding of the specific situation (or business challenge) and what has to be achieved with your particular management intervention. While this might sound obvious, there are many cases where expectations, contextual factors and formal objectives are not taken into consideration. As a consequence, the decision quality is poor by design. By reminding us to briefly stop and ask what has to be decided (business problem/issue), who is involved, and what the desired outcome is, Evidence-based Management helps us to fully grasp the decision situation even under stress and to evaluate different sources of evidence critically before making a decision.
Evidence-based Management has critical thinking in its heart and points towards four types of evidence
The traditional intuition-based decision-making approach strongly relies on experience. Evidence-based Management makes us aware that experience or professional expertise is just one of four possible sources of evidence that should be considered for decision-making. Besides our professional expertise, Evidence-based Management points to organizational data, scientific literature and stakeholder values and concerns as additional sources of evidence (refer to above picture).
Depending on your time restrictions and the decision magnitute, do a comprehensive review of all four sources of evidence or just a brief mental “walk-through” in case you are already aware of them (e.g. from former decision processes). After you acquired the evidence, critically appraise it and aggregate the key take-aways in a way such that you can apply them in your specific business setting. Finally, assess the outcome and align your intervention strategy accordingly.
Evidence-based Management puts strong emphasis on contextual and situational factors
Evidence-based Management combines qualitative and quantitative evidence, which makes it very attractive for complex business settings. There is for instance a strong body of quantitative evidence available on the effect of goal agreements on performance. This makes it easy to conclude that goal setting theory (the theoretical foundation behind goal agreements) has a positive impact on performance. However, in order to better understand the “how” and “why”, Evidence-based Management encourages us to also take a look at qualitative studies that look beyond whether goal setting works or not.
Having stakeholders and experts considered as source of evidence also increases the contextual embeddedness of the decision-making process. In particular strategic decisions are usually complex by nature. Taking a holistic approach as suggested by Evidence-based Management is the very basis to coping with a high level of complexity in a VUCA world.
Evidence-based Management encourages to think twice before starting an intervention
‘Getting things done’ is one of the overarching themes that guides the way managers and professionals act in organizations. This focus on delivering results usually come along with an incline towards action. This action-orientation is reinforced by the unspoken expectation that hard work is the only way to make an organization succeed. While it has not to be a bad thing to be action-oriented, it could be when the actions taken are not aligned with the way organizations operate.
However, many managers and professionals tend to overact in times of change, crisis and stress. Evidence-based Management is rooted in social sciences and thus relies on the most recent insights into how organizations operate. And more often than not, there is no need for interventions on a micro-level, but for an integrated and holistic approach on how to help people to deliver high performance.
There are resources available provide guidance on how to use evidence-based Management effectively
Evidence-based Management is part of a broader movement that targets at increasing decision-making quality in organizations crucial for our society. There are resources around the web that can help you on the way to becoming an Evidence-based Professional. The Center for Evidence-based Management, also called CEBMa, is the leading authority in the area of evidence-based Management and leadership.
