This document provides a summary of a case study on a successful ERP implementation at an Irish subsidiary of a UK multinational company. The case study uses the Project Management Body of Knowledge (PMBOK) framework to analyze the project management approach. Interviews and questionnaires were conducted with the local implementation team over time to understand how their perceptions of the challenges evolved. The case study found that while the PMBOK framework broadly applies to ERP projects, some aspects require different emphasis due to the scope and complexity of ERP implementations.
