Management, language: English, abstract: "In the twenty-first century,
IT architecture will be the determining factor. The factor that
separates the winners from the losers, the successful and the failures,

(Jeffery & Leliveld, 2004). Regarding Fairbanks (2010, p. 8) a major
cause for this is an insufficient risk management in the IT architecture
development in principle. Therefore many IT architects ask themselves,
how they could identify and prioritize their project's most pressing
risks? Which architecture and design techniques mitigate the risks and
what is the amount of risk reduction? In order to answer these
questions, section 2.1 defines the terms architecture and enterprise
architecture before it deals with the IT architecture itself. The
following section 2.2 gives an overview of risk and risk management in
general. Chapter 3 presents the main chapter of this assignment. At
first, it gives a brief overview of the role of IT risk management in
the scope of strategic management. The next two sections illustrate the
IT risk management and IT risk management process. In addition to that,
section 3.4 describes different instruments fo
