A decision model and system for planning and adapting the configuration of enterprise information systems

The decision to invest in an enterprise information system is usually made without taking into account the different types of subsequent decisions and without understanding the hidden implications of making them. This paper presents a decision-making model named DecISIonAl used to evaluate and manage implementation risks on ERP and CRM projects before the actual investment is made. This model was implemented into a web-based system to facilitate configuring, comparing, and selecting implementation plans by evaluating their impact in terms of cost, time, benefits, human resources capabilities, and risks. We apply our decision model to investment case studies in two enterprises. The results show a level of compliance between 80% and 83% when comparing the implications estimated by simulated scenarios and the actual investments.
