Abstract: Sustainability or sustainability development has been a major topic of discussion over the last couple of years. Project management is also a discipline that is starting to focus on sustainability, but the focus is more on the environmental aspect of the project itself. Information systems (IS) projects do not have such a major impact on the environment as construction and engineering projects do. Should project managers that are implementing these ‘soft’ projects be concerned about sustainability? There is currently little or no knowledge about sustainability within the IS domain and whether sustainability is incorporated at all within IS projects. A structured questionnaire was adapted based on previous studies. It was circulated to the project management community within South Africa and a total of 1 099 responses were received. The responses covered all industries and for the purpose of this article, 387 IS projects (35.2% of the total projects) were analysed to determine the level of project management sustainability maturity. The objective of the study was to determine the level of capability regarding sustainability.
