The importance of system quality, information quality and systems success has been recognized by many researchers as key ingredients in developing a competitive advantage. New scales and measures, along with continued research into organizational effectiveness and user satisfaction are needed.

This website incorporates a modification proposed by Pitt and Watson3, which adds a Service Quality module.
