The maintenance & operations fields are & will increasingly be dominated by information fragmentation, product & process complexities, increasingly important needs to access relevant knowledge in an ever faster pace, increased need for accurate analysis & implementation of the analysis results & need for more effective & accurate management.In addition to this the created solutions & processes also has to be effectively used in different work contexts including mobile work contexts & supporting interoperability with external ICT systems & processes. ICT-based frameworks should according to the factors & challenges described above be structured to be flexible enough to over time integrate new types of information & services, be usable both internally in the industrial facilities & in the field (mobile) & effectively act as a bridge between older & future ICT-systems. An example of such an integration approach is the PROTEUS project aiming at developing an "integrating" platform for maintenance management. The frameworks described during this presentation also will include modularised integration of not only data in existing maintenance systems and knowledge resources but also integration with web services (SOA), access & management of external computational services (analysis). These different modules will be accessible more dynamically than earlier web-based solutions. This in an environment that support several parallel work contexts & use not only in fixed networks but also in mobile / nomadic settings allowing a high degree of flexibility for the maintenance & operations staff.
