Software is created by people---software engineers---working in varied environments, under various conditions. Thus understanding cooperative and human aspect of software development is crucial to comprehend how methods and tools are used, and thereby improving the creation and maintenance of software. Inspired by the hosting country's concept of co-responsibility -- ubuntu -- we especially invited contributions that address community-based development like open source development and sustainability of ICT eco-systems.

We report a study where software project risk factors were solicited in Nigeria. The study repeats a research design, which has been used in a Delphi study in the U.S., Finland, and Hong Kong to rank software development risks. The study produces a rank-order list of software risk factors and compares results with the earlier study, showing significant differences. Obtained rankings signal the importance of the infrastructure related and socio-economic software risks in developing countries like Nigeria. This demonstrates the importance of understanding the broader socio-economic context in identifying and managing software risks. The study also shows that some risks in Nigeria are located on a different scale. The choice of contingent mitigation strategies of project managers play a less important role, because the risks are so deeply engrained with the poor quality of basic infrastructure services.
