The software development process is increasingly depending on various Computer-Aided Software (CAS). Simultaneously using these tools bring some problems, including non-customized development process, inconsistent process data and inefficient process management. To deal with these problems, a software development process management system that supports multi-tool collaboration was proposed. The hierarchical architecture system was developed on workflow design by analyzing software development process and studying the software engineering development model that supports fast iteration and tends to process management. Besides, the system was rigorously tested under 576 test cases. As a result the pass rate is 85%, which is able to meet the majority of tool collaboration needs, including definable development process, consistent interaction data and available process management. The system has been used by seven development teams with about 200 developers. The feedback results from the managers, developers and testers show that this system saves the time of weekly meetings, facilitates the management of development tasks, and significantly improves the development efficiency.
