The concentrated and implementation-oriented support in this research guide aims to empower students and doctoral candidates to work on a chosen research topic in a structured process with defined and traceable sub-steps, so that meaningful scientific results can emerge from it. The disciplinary focus is on economics, specifically business administration. However, the scientific theoretical foundation of critical rationalism and scientific realism is also applicable to many other scientific disciplines. Therefore, the approach presented here is nearly universally transferable and applicable. The 3rd edition has been revised and expanded, particularly in the topics of "document management" and "citation style.".
