This article aims at illustrating the use of core task modelling on a system level and attempts to show its relevance to cultural assessment. The methodology that was used in a case study consists of an iterative process of core task modelling, organisational culture research and organisational assessment. The case study was conducted in a nuclear power plant's (NPP's) maintenance department. The maintenance task, its goals, critical demands and the demands for the working practices were conceptualised by core task analysis. The organisational culture of the maintenance department was explored with interviews, a survey and workgroups. The results show three critical demands and three instrumental demands to be controlled on all levels in the organisation. The maintenance culture must support the activity of balancing between these distinct requirements. The core task model was used in assessing the characteristics of the maintenance culture. This was done through analysing the unity of the personnel's conceptions concerning the organisation, its tasks, goals and values. The relevance of this approach to organisational development is discussed.
