Making major changes in enterprise informationsystems, such as large IT-investments, often have asignificant impact on business operations. Moreover, whendeliberating which IT-changes to make, the consequencesof choosing a certain scenario may be difficult to grasp.One way to ascertain the quality of IT investment decisionsis through the use of methods from decision theory. Thispaper proposes the use of one such method to facilitateIT-investment decision making, viz. extended influence diagrams.An extended influence diagram is a tool able tocompletely describe and analyse a decision situation. Theapplicability of extended influence diagrams is demonstratedat the end of the paper by using an extended influencediagram in combination with the ISO/IEC 9126 softwarequality characteristics and metrics as means to assist adecision maker in a decision regarding an IT-investment.
