 process or to the solution of a design issue or other problems."[http://www.sti-studies.de/fileadmin/articles/kleemannetalstivol0no0.pdf] Although we agree that simultaneous or collaborative work is a significant type of crowdsourcing, it is not the only one. The Best Practices entry for crowdwork, developed last year and reposted on [[Class 0]], divides crowdwork into three categories: "First, a large group of workers may do microtasks to complete a whole project; the best-known platform in this arena is Amazon Mechanical Turk. Second, companies may use cloudwork platforms to connect with individual workers, or a small group of workers, who then complete larger jobs (e.g., Elance[http://www.elance.com/p/landing/buyerA0.html] and oDesk[http://www.odesk.com/#reloaded]). Finally, a company may run 'contests,' where numerous workers complete a task and only the speediest or best worker is paid (e.g., InnoCentive[https://www0.innocentive.com/] and Worth0000[http://www.worth0000.com/]). In some contests, the company commits to picking at least one winner; in others, there is no such guarantee." It is clear that when the crowdsourcing takes the form of competitive bidding, not every participant works on a single aspect of the task; each of them works on the whole task, and they do not have to work at the same time. Only the final winner gets compensated. It is possible that only one individual or organization joins the bidding process and no competing parties are involved.
