One of the important tasks of science is to respond effectively to the challenges that arise during the ever-accelerating social and economic changes, and to provide appropriate answers to the questions that arise. It is useful to provide guidance for decision-makers at the macro and micro levels. It does this in such a way that there is no salutary „best practice” for the interpretation and explanation of complex phenomena. There are better or worse solutions to problems that fall within the scope of „good practice”.
