What happens when end users do not respect the IS organization and have high computer self-efficacy? Will the end users develop usable systems and will they ignore IS? This chapter reports on a study of end-user computing within the engineering organizations of an electric utility undergoing deregulation. The study was initiated when management perceived that too much engineering time was spent doing IS functions. The study found that there was significant effort being expended on system development, support, and ad hoc use. Several issues were identified affecting system development, use of programming standards, documentation, infrastructure integration, and system support.
