What is Perceived Ease of Use (PEOU)

Enterprise Resource Planning (ERP) systems have been implemented in numerous organizations over the last decade. However, research indicates that successful implementation of ERP solutions does not necessarily lead to successful ERP usage. ERP systems benefit organizations only to the extent that users accept and utilize them frequently and extensively. To improve the efficiency and effectiveness of ERP systems in the operation phase, organizations need to research the factors that impact user satisfaction. In this area, the Technological Acceptance Model (TAM) proposed by Davis (1989) has been widely used as it can enhance understanding of the influences that increase the efficiency and effectiveness of ERP system use. Regardless of ERP complexity and ERP implementation failure, very few studies have been conducted to examine technology acceptance, especially when dealing with autonomous ERP users and including more external factors, which can influence users’ acceptance of ERP system. Because ERP solutions are implemented by different methodologies and some are more present at large organizations than at small and mid-sized organizations, the authors research and compare the importance of external factors of two global solutions—namely, SAP and Microsoft Dynamics NAV—regarding user acceptance. The chapter contributes to the body of knowledge in this specific area.
