Maintenance core task and maintenance culture

The aim of the study reported here was to develop a methodology for modeling the maintenance core task and assessing the maintenance culture. The case study was carried out at the Loviisa nuclear power plant in Finland. Maintenance task, its goals, critical demands and the demands for the actual organisation of the maintenance were conceptualised by core task analysis. The organisational culture of maintenance department was inspected by interviews, observation, survey and workgroups. The core task model was used to assess the safety and efficiency of the maintenance culture. Results show three critical demands and three instrumental demands to be controlled in all levels of the organisation. The culture must support this. Implications of these demands for development of organisational culture are discussed.
