    This paper classifies and explores the benefits of Enterprise Resource Planning (ERP) systems using the individual manufacturing facility as the level of analysis. We focused on German companies using SAP R/3. Two successful cases are described in detail.The cases revealed that remarkable benefits have been realized in the following categories: „Process efficiency (business processes)”, „Market efficiency (market and customer orientation)”, „Resource efficiency (productivity and profitability)”, and „Delegation efficiency (gathering of information)”. Data standardization and integration explain many of these benefits. However, the users complain about higher workloads as a result of the complexity and required data structures of these systems. Therefore, they show lower acceptance for the new system.
