Research note: theoretical optimisation of IT/IS investments

The justification of information technology (IT) is inherently fuzzy, both in theory and practice. This is due to the largely intangible dimensions of IT projects. In view of this, this research note presents the results of ongoing research, in the application of Fuzzy Cognitive Mapping (FCM), as a tool to identify complex functional interrelationships associated with the justification of IT. This paper presents a theoretical functional model which describes these relationships and, by using an FCM, further interrelationships are developed in the context of justifying IT projects. A procedure which would address the optimisation of these intangible relationships in the form of a genetic algorithm (GA) is proposed as a process for investment justification.
