This work has asproposal a research and analisys of the apparently large demand of resources necessary to upgradethe versions of ERP R/3 systems. Firstly, a review in literature is made to present the arquitecture,characteristics and concepts of modules and funcionalities of these ERPs systems. It is alsoincluded the study of the life cicle of ERPs systems and its interfaces with legacy systems.

After these studies, twoquestionnaires are made to obtain data.
