The project is largely distributed across six R&D centers in the US, France, Japan and China. Each center has sub-projects that have a clearly defined responsibility with either Framework or Application-Components developments. All sub-projects share the common master plan for both development and testing. Furthermore, all unit tests and "Level-1" Application-Component tests for particular applications are globally distributed and owned by each sub-project team. Together with the master test plan, a rigorous Application-Component Test procedure/process is also in place to guarantee the success of the final system integration tests. Results from the distributed developments and the distributed first-level tests are finally assembled in one place, Beijing, for system integration and acceptance tests.
