It is widely accepted that information systems have an influence on performance. However, literature is still in disagreement about the strength and direction of the influence. Does system use affects users’ task performance positively, negatively, or insignificantly? This knowledge gap makes it difficult for us to understand the deeper interrelations between system use and task performance.
The unresolved situation makes it hard for practitioners to justify IT investments by expected improvement of task performance. Furthermore, it is not clear how systems should ideally be used in order to maximize task performance and consequently create most value through system use.
