A Case Study on Call for Implementation

With the growth of the internet and open software, there are additional software developers available from the open community that can participate in the development of software application systems. Aiming to leverage these resources, a new development model, CFI (call for implementation), is proposed. The basic idea of CFI is to publish some part of a software project to the open community, whole or part, in certain phases of the software development lifecycle to call for implementation. This paper discusses the basic concept and method for a software development process in CFI mode. Two different modes of CFI with different granularities are analyzed. And one of the CFI modes, fine-granularity-CFI mode, is thoroughly discussed including the main methods and basic steps. To verify the ideas a pilot project, an online store system, is built up with the CFI development process. The online store system takes the traditional Model-View-Control architecture and some common technologies such as Struts, Hibernate, Spring are used. The result shows that this new kind of software development mode is feasible though there are many problems that are still requiring further study.
