Crowdsourcing has become a popular option for rapid acquisition, with reported benefits such as shortened schedule due to mass parallel development, innovative solutions based on the "wisdom of crowds", and reduced cost due to the pre-pricing and bidding effects. However, most of existing studies on software crowdsourcing are focusing on individual task(More)
Context: The success of crowdsourced software development (CSD) depends on a large crowd of trustworthy software workers who are registering and submitting for their interested tasks in exchange of financial gains. Preliminary analysis on software worker behaviors reveals an alarming task-quitting rate of 82.9%. Goal: The objective of this study is to(More)

However, as one of the most important motivating factors for on line crowdsourcing workers, it is more important for the task requesters to not only be able to estimate "what the nominal(More)
As more and more companies are trying to leverage crowdsourcing to reduce cost and time-to-market of software production, it is very important to better understand the dynamics of crowdsourced software development in order to fully realize its benefits and avoid hidden pitfalls. This paper presents a systems dynamic model for crowdsourced software(More)
There is an emergent trend in software development projects that mini-tasks can be crowdsourced to achieve rapid development and delivery. For software managers requesting crowdsourcing services, it is beneficial to be able to evaluate and assure the availability and performance of trustable workers on their tasks. However, existing rating systems are(More)
