The impact of senior management involvement, organisational commitment and group efficacy on ITIL implementation benefits

Senior management involvement, organisational commitment and group efficacy are expected to have a positive impact on Information Technology Infrastructure Library (ITIL) implementation benefits. Specifically, more involvement, commitment and efficacy should produce greater achievement. Analysing data from a survey of 446 Nordic ITIL experts, this paper examines the relationships between these predictor factors and benefits, and investigates which is most critical. This study verifies the importance of all factors, but contrary to previous research, which has especially emphasised the role of senior management, in this research, group efficacy has proved to be the strongest predictor, indicating that the capabilities of those involved in the ITIL implementation are more important for realising the potential benefits than is senior management involvement. This work contributes to theorising in an important area of practice by testing and validating measurements and instruments for an empirical-based model of ITIL implementation.
