Organisations rely on their enterprise systems (ES) to integrate and optimise business processes, automate business transactions and share context-rich information to support decision making, according to the literature. But does this happen and how? This study examines key benefits that organisations generally seek from ES implementations, how ES data are transformed into knowledge, how this knowledge is utilised to achieve business benefits and the critical success factors for this process. Findings indicate that key benefits New Zealand organisations expect from ES include improve information flow, reduce out-of-inventory events and implement process efficiencies. An important finding is that New Zealand companies have only recently started tracking benefits through analytical processes to optimise and realise business value from their ES investment. Implications for practice are discussed with a focus on usability of ES and its information.
