Evidence-Based Management

The aims of our academic research are besides the development of basic knowledge the promotion of practice-related knowledge. Managerial staff in practice have to take complex decisions that imply far-reaching consequences. However, these decisions are frequently based on indistinct premises (e.g. management fashions, imitation behavior of competitors, outdated knowledge). When their decisions are based on experiences, they consist most likely of case studies. But only a small number of examples are drawn from practice for those case studies in order to make a decision. 

Researcher within the principle of the evidence-based management try to give practice-related managerial recommendations on the basis of “evidence”, that is to say sound results from scientific examinations. Those examinations can be so-called primary studies by which a particular hypothesis can be tested by both a self-examined sample with a substantial number and by strict statistical methods. Otherwise, those examinations can be secondary studies where every available study concerning one hypothesis will be aggregated and combined. Thereby, an overall assessment of the whole evidence for the respective hypothesis can be build.

One powerful examination method within this context is the „meta-analysis“. Thereby, statistical measures that represent the correlations of interest (e.g. the link between the conducting of a recruitment measure and professional success of the recruited applicants) are aggregated and according to statistical methods a “medium effect size” is being calculated. Moreover, meta-analyses enable to analyze reasons whether and why there are differences between the outcomes of the examined studies.

The evidence-based medicine serves as an example for the evidence-based management. Since the 199s, the evidence-based medicine endeavors to collect every evidence in favor or against certain medical therapies.
