The study examines connections between the outcome of software development projects and contract type, project size, benefits management practices, and agile practices. The collected information relates to 146 software projects—half from 2007-2012 and the other half from 2015-2017. Binary logistic models built to explain successful and problematic software development projects revealed that the use of time and materials contracts, as opposed to fixed price contracts, was associated with fourteen times higher likelihood of project success. Other practices with a strong connection to project outcome included frequent delivery to production and benefit management during project execution. We found that the explanatory strength of a practice sometimes differs substantially in models of successful and in models of problematic projects, as well as over time.
