EUCS test-retest reliability in representational model decision support systems

Abstract A test–retest reliability study of an end-user computing satisfaction instrument was conducted. The instrument was distributed to real-world representational decision support system users through a mail survey. One month later, follow-up surveys were mailed asking the original respondents to again evaluate the same system. The data sets were compared and suggest that the instrument is internally consistent and stable when applied to its users.
