Software supply chains (keynote)

It has long been desired to build software systems predominantly through the composition of existing software components. The need for such a production model is growing given the increasing use and reliance on software for almost everything we interact with from toasters to airplanes. For some kinds of systems, we have come a long way towards meeting the production via composition through the use of libraries, frameworks and plugin architectures. But, for other systems that require tight integrations of components produced by different suppliers, we are not yet able to reliably engineer a software supply chain. In this talk, I will outline some achievements in software supply chains and describe some of the challenges that need to be met to productively provide the systems of the future.
