AbstractThe impacts of IT/IS on organizations gave rise to a great deal of interest from the researchers during the last decades. However, studies on the impacts of IT/IS on the performance of engineering projects are less numerous. Moreover, the impacts from IT/IS on engineering projects are rarely based on real data of projects. The objective of this study is to investigate, from real project data, the level of utilization of a project management software package, developed by an engineering construction firm recognized internationally, and its link with project performance. Results stemming from non-parametric tests and correlation analyses show that the level of use of the software, and some of its subsystems, appears to be linked to project performance.
