This presentation goes beyond those one-liners on why we should or should not use open source software in enterprise environments. During this talk we will translate open source software to a sensible set of software properties and how we can measure and decide whether these properties are useful and therefore desirable for enterprise environments. The speaker will dispel some well-know myths and view points on open source software. So when you are interested in recognizing and deciding on the true value of open source software for your enterprise be sure to attend this presentation.
