Practice has shown that big data technology can empower the management process. As an important project in the complex high-end program of commercial aircraft development, the commercial aircraft MOC9 test project will generate a large amount of project management data during development. Therefore, it is necessary to study how to use big data technology to promote such projects to achieve project objectives. Based on the characteristics of the MOC9 test project under the commercial aircraft development program and its demand for big data management, this article conducts study on the MOC9 test project from multiple aspects such as architecture planning, data acquisition and storage, data cleaning and processing, analysis mining, and visual display, combined with big data technology processing processes and methods. The study results show that establishing a quantitative visual model for MOC9 projects through big data technology is very helpful for project managers to master the overall situation of the project, locate the root causes of problems, and identify potential risks of the project.
