In this paper the idea that certain approaches to ethics have better compatibility with certain public administration systems is explored. Inquiry starts with an overview of general approaches to ethics management. Then some country-cases are discussed to explore which approaches are actually used. Finally an answer to the question, if there is any regularity in the use of certain ethics management approaches in certain public administration systems is searched. Some ideas about compatibility of public administration systems with ethics management are sketched. That is an attempt to expand overwhelming dualistic continuum of ethics management.
