The purpose of this chapter is to compare the country models of the performance of the six country cases and the extent to which they have been implemented. The analysis of performance dimensions follows the categories developed for the country overviews in the appendix: design features of measurement, incorporation of information, using information, and managing and governing performance. The approach first evaluates the systems in terms of their official frameworks, aspirations and intentions. This involves starting with the ideal types of Managements of Performances and Performance Management and the country models that fit each. Then comparisons of the basic aspects of the country models identified with Performance Management are discussed. The second part addresses how the country model works in practice, the analysis examining practice against the main dimensions of performance, and making comparisons among the systems where possible.
