Competitive advantage is traditionally an outcome of leveraging people, processes and technologies. Today organisations have several technologies with disparate information. Information integration may assist organisations to remain competitive. Organisations that have technology which manage or control assets have particular integration challenges compared to organisations with corporate business areas. This is because organisations do not view technology managing infrastructure assets in the same way as managing functions such as finance, retail and human resources. The paper defines a current, asset management based taxonomy for organisations integrating Operational and Information Technology. It identifies a number of challenges, such as the commitment to information integration, organisation-wide governance and architectural approaches as well as the aligning of operational open standards with existing information technology standards. Furthermore it highlights opportunities for further research in the area.
