The need for rigorous academic investigation into open source software (OSS) is pronounced. If the media hype surrounding the topic since 1998 has a kernel of truth, then OSS promises to revolutionise the ways in which organizations build, sell, buy, use and exploit software systems.

This panel, which takes the form of a debate, will provide audience members with an up-to-date understanding of OSS built upon the emerging research literature, and detailed arguments both for and against the assertion that open source is revolutionising the software industry.
