AbstractOrganisations establish projects to realise unique time-limited enterprises efficiently. Particularly in industry this practice is common for large-scale projects. The IT management supporting such industry projects often faces special, characteristic challenges.This paper addresses how existing concepts of strategic IT management can be applied in the context of large-scale industry projects. A general reference model is defined for future application by IT departments in large-scale industrial projects.This model is based on five large-scale industry projects that were analysed consistently through a case study methodology: Digital mobile radio BOS (Cassidian/EADS), Elbphilharmonie Hamburg (HOCHTIEF), Genetic power plant (Siemens), Nord Stream Pipeline (Nord Stream), Polyethylene Plant SHARQ (Linde).The reference model for project IT management is structured along the three Business Engineering design layers: strategy, processes and realisation. Base on scientific literature and case studies the model provides practical recommendations, success factors and common pitfalls.The IT management strategy should integrate with overall project management. As such, IT strategy is a tool to position IT management internally as a process integrator for other operational departments. The identification of technical solutions should focus on proven technologies with prior experience transferred to future projects wherever possible.To design IT management processes, the existing industry frameworks and standards are aligned to a specific project's needs, taking account of the planned time constraints and then consolidated into a comprehensive process template. With regard to the requirement profile, IT management should adopt a role differentiated going from IT-central, over Business-drives-IT to IT-enables-Business in the internal project Business-IT alignment.Information security has a high impact on successful project delivery, so employees and contractors should be aware of the risks, e.g. via guidelines and trainings. IT management employees must also be able to relate to the working methods of foreign partners, and account for cultural differences in their IT project planning and realisation. Cooperation with proven "preferred suppliers" is beneficial, enabling relationships, trust and understanding to develop.The reference model design is determined by six influential factors: Project volume, time constraints from an IT perspective, applicable existing IT experience, project internationality, project independence and the relationship or impact of IT to the project.
