Crowdwork is becoming more and more popular. Crowdwork refers to outsourcing paid tasks by a company or an individual to a mass of unknown individuals (crowdworker) via crowdworking platforms, which are also known as Online Labour Platforms. Because of an inherent anonymity in crowdworking, each crowdworking platform makes use of individual governance mechanisms to ensure that crowdworkers and companies act in a desirable way. However, the problem with these mechanisms is that they are especially designed for certain platforms. Therefore, these mechanisms cannot be adapted and used by other platforms. In this paper we empirically identify the specific mechanisms that are used by different platform provider. We then cluster these insights into general reference process modules. The resulting reference process modules serve crowdworking platform providers as a blueprint for effectively govern and control the crowd along the whole crowdworking process.
