New York State Agencies: A Case Study for Analyzing the Process of Legacy System Migration Ingrid Fisher Marianne Bradford |
ABSTRACT: Part I The first of a two-part case, Part I explains the problems organizations can encounter when confronted with the update or conversion of a large-scale legacy information system (IS). Set in the context of New York State government, the case illustrates the additional complexities of legacy system migration when organizations operate under legal constraints. Systems issues addressed include: (1) the role of strategic planning for IS, (2) the importance of stakeholder analysis when making changes to systems, (3) organizational approaches to systems implementation and (4) business process analysis. This case is appropriate for use in either an undergraduate or graduate Accounting Information Systems course and offers a flexible approach to adoption, ranging from comprehensive adoption of all topics in both parts of the case to specific topics within either part.
