Research protocol for a case study of crowdsourcing software development

Crowdsourcing is an emerging topic within software engineering research. This report presents the protocol for our case study of crowdsourcing at a multi-national company. The findings of the case study are presented in a paper in the proceedings of the 36th International Conference on Software Engineering (2014) (see ref. [37]). This protocol presents additional details that provide more insight regarding the background, design and execution of our study. The research design can also be used for replicating the case study so as to be able to more easily compare different case studies
