We use partial least squares structural equation modeling to test five main hypotheses with survey data from 248 managers with extensive IT/IS project involvement. The results demonstrate that mismatches between real and perceived project management performance indeed occur. They are predominantly driven by poor expectation management before and during the execution of IT projects, as well as by a low project sponsor commitment. A discussion of the findings and limitations, as well as suggestions for future research, conclude the article.10 pagesengAttribution-NonCommercial-NoDerivatives 4.0 InternationalProject Management PerformanceProject SuccessProject FailurePerceptionConference Paper10.24251/HICSS.2017.624
