The paper focuses on the method of formal concept analysis in data analyzing for software process improve-ment. It sets up that not only the Software Quality Guarantee Platform being developed should have the commonfunctions including enterprise process defining, process cutting out, executing and monitoring, and the normal dataanalysis tools such as OLAP, but also one should develop the novel data analysis tools based on formal methodologyby starting with maturity definition of process data, so as to discover valuable new knowledge from large database andsupport continuous software process improvement. Further more ,the paper demonstrates the software process dataanalysis using concept lattice in an example.
