Contemporary administrative systems are shaped in part by their past and by the conceptions of good administration that are embedded in administrative culture. Administrative traditions shape contemporary administration in Europe and have been heavily influenced by European models. Administrative tradition means an historically based set of values, structures, and relationships with other institutions that define the nature of appropriate public administration. Seven dimensions can be used to both define these traditions and categorize public administration into four groups of nations. This explanation is similar to cultural explanations, but it includes the influence of structures as well as ideas. While the model of traditions developed is based largely on European and North American experiences, it can also be applied to a much broader range of administrative systems.
