A Structured Transformation Approach for Legacy Information Systems - A Cash Receipts/Reimbursements Example

Legacy information systems are difficult to transform into the new or upgraded information systems. Part of the reason is being the incompatibility and the unscalability between the systems. In this study, we propose and present a structured transit approach and process to provide an alternative in order to guide and ease the large scale legacy system transformation. In this paper, we describe a real world case study which we have applied the structured transit method successfully in 1997-1998. This transformation project is a two-year companywide business process reengineering on their financial and accounting information systems. Through this project, We confirm our perception that the structured problem and solution domains require the structured techniques to tackle and to solve the compatablity and scalability issues because the structural discrepancy represents the core of the above problems originally. We give the details of the application in five analysis tasks: the functiona...
