This paper explains a growing function in today’s public organizations: the technostructure. It reports on the outcomes of an educational programme to develop teams comprising HR, financial and organizational development managers in a Swedish municipality in order to achieve joint support to line managers. The three groups emphasized the importance of their dissimilar work areas and their differences vis-a-vis other administrative occupations with presumably simpler tasks, and showed their indispensability. The groups’ relations were strengthened, but not their actual joint support to line managers. The paper contributes to the literature on professionalized technostructures and organizational change.
