A number of trends under the broad banner of crowdsourcing are beginning to fundamentally disrupt the way in which software is engineered. Programmers increasingly rely on crowdsourced knowledge and code, as they look to Q&A sites for answers or use code from publicly posted snippets. Programmers play, compete, and learn with the crowd, engaging in programming competitions and puzzles with crowds of programmers. Online IDEs make possible radically new forms of collaboration, allowing developers to synchronously program with crowds of distributed programmers. Programmers' reputation is increasingly visible on Q&A sites and public code repositories, opening new possibilities in how developers find jobs and companies identify talent. Crowds of non-programmers increasingly participate in development, usability testing software or even constructing specifications while playing games. Crowdfunding democratizes choices about which software is built, broadening the software which might be feasibly constructed. Approaches for crowd development seek to microtask software development, dramatically increasing participation in open source by enabling software projects to be built through casual, transient work.

CSI-SE seeks to understand how crowdsourcing is shaping and disrupting software development, shedding light on the opportunities and challenges. We encourage submissions of studies, systems, and techniques relevant to the application of crowdsourcing (broadly construed) to software engineering.

CSI-SE is a one day workshop composed of four sessions. A morning session will be devoted to invited talks by leaders in crowdsourcing in software engineering. Two paper sessions will provide opportunities for authors to disseminate their work and interact with other researchers working in the area of crowdsourcing in software engineering. The workshop will close with a highly interactive discussion session.
