To enhance maintenance performance, maintenance integration with relevant activities should be planned and performed. In a digitalised industry, maintenance integration has to deal with various and heterogynous technologies. As the integration of such disparate technologies can be complex, this paper proposes a framework that provides the steps required for the successful integration of digitalised and automated maintenance across the relevant working areas. To develop this framework, we first identified relevant working areas to integrate maintenance with. Next, we identified integration success factors which are then considered in the framework development. The framework was then implemented in a real case study, and results showed that the integration tasks were completed successfully. Based on the case study, the framework provides guidelines for successfully integrating maintenance in a systematic way across the relevant working areas.
