effectiveness and ease of use were deduced from the element strategic use of IT. The criterion general applicability was added separately. After comparison of methods, IT governance matrix of Weill and Ross was selected to describe IT governance structures. IT governance mechanism of De Haes and Van Grembergen is selected to describe IT governance processes and relations. These two methods make up the component IT governance description of IT governance assessment method. Business/IT alignment measurement of Luftman is selected to measure IT governance effectiveness measurement. This method makes up the component IT governance effectiveness measurement. IT Governance assessment method is now filled with selected methods for the components IT governance description and IT governance effectiveness measurement (figure 6). These methods will further be improved and combined to develop the final IT governance assessment method in Chapter 4. Figure 6. IT governance assessment method with selected methods Improvement of methods for IT Governance assessment method Introduction In the previous chapter methods were selected that are used for the development of IT governance assessment method. In this chapter the methods IT governance matrix, IT governance mechanisms and business/IT alignment will be modified to improve IT governance description and IT governance effectiveness measurement. The improved methods will then be combined to form together the IT governance assessment method. Modification of IT governance matrix In this section IT governance matrix will be modified by including IT governance element of control identified in chapter 2. By incorporating the element of control, IT governance matrix can be improved. The improved IT governance matrix can describe IT governance of organizations more comprehensive. The matrix is also able to provide prescription about how IT governance should be organized. In order to incorporate control in the matrix, the concept of control in corporate governance is used.
