Understanding Functional Reuse of ERP Requirements in the Telecommunication Sector: An Empirical Study

This paper is an empirical study on the application of Function Points (FP) and a FP-based reuse measurement model in Enterprise Resource Planning (ERP) projects in three organizations in the telecommunication sector. The findings of the study are used to compare the requirements reuse for one particular package, namely SAP. We found (1) that reuse is possible up to 80% at best, and (2) that, while for some modules, the organizations achieved the same levels of reuse, for other modules, the organizations´ levels of reuse varied widely. We conclude with some implications of our findings for both practitioners and researchers.
