EBARA's e-Human's is a total information management system which supports large-scale innovations, such as for document management, project management and external procurement functions, in the IT-infrastructure for environmental engineering business. A shift from mainframe to open server systems is now taking place in this field of business. In 2002, the total number of servers within EBARA for subsystems reached 170, including 5 host systems. This posed serious security and management risk, not to mention high management costs and difficulties in the management of open systems. Progress in IT is making it imperative to achieve co-ownership and active use of information among different EBARA entities and clients, while maintaining adequate security. These factors are becoming indispensable for boosting corporate competitiveness. The following discusses the application of e-Human's to environment engineering business and innovations made in EBARA's IT-infrastructure while solving abovementioned problems.
