This book relies on two major methodological pillars: ideal types, and concrete country case studies that result in a description of a country model. The empirical material used is based on comparative research that considers the ‘official’ or dominant performance models of central governments. The structure of this empirical material relies on ideal types as defined by Weber at the beginning of the twentieth century in Germany. For that purpose an overview Table of four ideal types is developed. Six countries (Australia, Canada, the Netherlands, Sweden, UK and USA) are examined using the scheme for analysing managing of performances and defining country models. Finally, several existing, survey-based checklists are presented.
