Overhauling Legacy Enterprise Software Applications with a Concept Refinement Process Model

Abstract

Currently, there are many legacy enterprise software applications in active deployment that are outdated. These large legacy applications are rapidly becoming less practical for both the organizations they service, and for the organizations responsible for servicing them. Due to this problem, organizations utilizing legacy enterprise software applications are looking for feasible methods for overhauling them. This thesis establishes a process model for refining the initial concept associated with overhauling legacy enterprise software applications, and examines a case study of that process as applied to a real-world legacy software system.
