Validation of the End-User Computing Satisfaction Instrument in Case Tool Environments

This article focuses on the psychometric stability of the end-user computing satisfaction (EUCS) instrument by Doll and Torkzadeh (9) when applied to end-users of typical CASE tool software packages and systems software applications. Using a survey of 190 users, this research provides evidence that the EUCS instrument is a valid and reliable measure in CASE applications. Given this evidence, managers and software product developers can confidently apply the instrument in the investigation of competing tools, features, and technologies in CASE tool settings.
