Ideally, each IT project should be embedded in a strategically business context and a holistic IT architecture.

By this investment pattern, the economic benefit of these IT-Applications can not be assessed. In the past, several IT-Applications were developed or implemented (purchase-software), which have not been applied for Business-Process-Reengineering but only for the support of various business-functions. To improve the benefit of IT-investments, their impact on real existing business-processes must be analysed and proven. The enlargement of the value of IT through innovation and integration is the corporate goal. IT-decisions typically have enterprise-wide significance and Business-Process-Reengineering (BPR) is hard to imagine without IT-Application-Systems changes. Which goals should be traced in the IT-Business-Unit and which context exist between IT-Application-Systems and business- processes that are more or less supported by IT-Applications.

Corporate-Governance is faced with the challenge to develop and implement a meaningful IT-Strategy. In monetary terms, IT value represent the amount customers (internal and external) are willing to pay for their IT Applications. CIO therefore are urged to measure the value of their IT solutions in terms of their contribution to the companies success. Resent analysis show that competitive advantages grows increasingly out of the value of IT-Solutions. Gaining and maintaining competitive advantages becomes crucial for superior performance. Most companies are faced with slower growth and stronger competition nowadays. The significance of Modelling with UML- and XML-Notationġ0.
