This study draws on the findings of two cross-sectional surveys of the top 5,000 largest corporations in Taiwan, undertaken in 2003 and 2006. It presents the organisations' criteria for selecting enterprise resource planning (ERP) software package and its supplier. The different selection criteria for ERP software package and its supplier between the two investigative years are discussed. From the results, we also discovered that a number of selection criteria are highly related to a domestic or international ERP package's utilisation and ERP supplier's adoption.
