Abstract—The paper analyzes the current state of software system in a leading Saudi University described as ‘legacy system’ in terms of functionality and ability to be modified in the face of ever increasing e-government requirements. The natural course of action taken by CEOs in similar settings is purchasing and installing an entirely new system, a decision which inevitably entails the risks of costing huge sums of money and compromising older business models. Subsequently, lengthy and complicated setting up may be required and the new system therefore is not always financially viable. An alternative model to re-architect the legacy systems instead of installing a new one suddenly makes sense. We attempt to establish the viability of our approach and account for the commercial and practical advantages as opposed to the other solution. The proposed solution is the first step towards facilitating the adoption of e-business models to automate the entire processes within that institute.
