A new type of EIT that is being introduced in major corporations such as Dell Computers, is based on the idea of component systems, which are stand-alone software programs that can integrate with other such components with relative ease. Given the financial outlay for EITs, the evaluation and adoption of these systems is not something that can be completed haphazardly. This requirement is complicated by the relative infancy of models for the evaluation of componentized EITs. To this end, in this paper, we introduce a managerial multistage multiattribute decision model, consisting of the Analytical Hierarchy Process (AHP) model and the Supermatrix approach (also defined as the Analytical Network Processes (ANP) approach), to aid in determining the various benefits associated with these systems. This combination of models builds on earlier work that validates the Supermatrix approach for evaluating traditional EITs at a Fortune 100 organization. The aggregation of these benefits based on intra- and inter-functional factors is then measured against the costs of systems, thereby arriving at a ranking of functional component systems from a set of alternatives. Using an illustrative example the model is executed with sensitivity analysis and managerial implications identified.
