Abstract:With the rapid development of Internet technology, Crowdsourcing becomes a flexible and effective solution. Although it has been widely used in many fields, the application in the field of software development still exists many problems, such as lack of unified standard and development methods, no mature application platform, etc. Aiming at these problems, this paper puts forward a software development platform and a software development method, which can provide a train of thought and reference for the use of crowdsourcing software development to a certain extent.
