In this study we report on the benefits achieved from enterprise systems implementations. Building on the existing research this paper uses the expectation-benefits framework as an analytical lens to identify and understand realised benefits. The study comprises 14 empirical case studies that focus on projects to extend existing ERP and CRM implementations. The work serves two key objectives. First to gain greater insights into the range and scope of realised benefits and second to further validate the exp-ben framework. Benefits are identifed in all four areas of the exp-ben framework. Most notable is the continued focus on achieving integration and in the improvement of information quality and better business intelligence.
