In this successful textbook, now in its fourth edition, both the theory of organization and the design of organization are addressed. Within the framework of organizational theory, the most important organizational theoretical approaches are discussed: the Taylorist approach, the Human Relations approach, the institutional economics approach, the evolutionary theory approach, and others. The subject of organizational design includes not only the discussion of organizational structure and process organization but also the analysis and evaluation of organizational models: functional organization, divisional organization, holding, matrix organization, process organization, team models, learning organization, self-organization, collaborations, and social responsibility. The combination of theoretical foundation and detailed practical examples is supported by the didactic presentation.
