A decision framework for upgrading ERP systems

The paper proposes a structured decision-making approach for supporting ERP upgrade/replacement projects when new business requirements arise. The proposed framework is composed of three possible steps involving different levels of interventions with the aim of selecting the best ERP upgrade/replacement solution. In each step the Analytic Hierarchy Process (AHP) method is applied as an evaluation tool. Specifically, an illustrative application for increasing supply network coordination is described by considering "functionality factors", "vendor factors" and "software system factors".
