The subject matter of this thesis is governance principles in global management concepts and the application of such principles by managers at a local level. The thesis includes a case study on a foreign-owned Swedish group of companies that has introduced the management concept of High Performance Culture in all of its consolidated group countries. Global management concepts usually originate from the United States and make use of neorational governance principles. High Performance Culture is a management concept that puts increased performance and individualisation in the foreground. In addition, the concept advocates co-determination and self-development. The governance principles further promote employee autonomy orientation and self-development in addition to a leader-centric approach. The case study results indicate a discrepancy in the requirements of the governance principles of the management concept, highlighting the various dimensions of cultural layers and values to which managers in the same organisation are subject. The same values had an effect in different ways on the managers’ interpretation and handling of the management concept. This interpretation and handling of the management concept tools led to an implementation that partially opposed what the French management team and management concept advocated. The managers choosing to oppose the governance principles of the management concept can be seen as an example of modern individualism, according to which people are increasingly questioning rigid and hierarchic authority while showing initiative and assessing one’s own personal work. Hence, the values of modern individualism can act as a counterforce to neorational governance principles.
