Sampling Summary： （抽样汇总）

Sampling Factors:	Location (Not Relevant: All projects are in the same location, so this is not a relevant sampling factor) Customer (Not Relevant: Customers vary, but the work process has no difference. Hypothesis testing of the process performance parameters also indicates that customer is a not a relevant sampling factor) Size: Hypothesis testing of the process performance parameters indicates that size is a relevant sampling factor. Organizational Structure (Not Relevant: All projects are based in R&D center, so this is not a relevant sampling factor.) Type of Work (Not Relevant: All projects are software development type, so this is not a relevant sampling factor.)
Sampling Factor Values:	Large projects (Size): Size is greater than 350 FP less than 350 FP (Size): Size is less than 350 FP
Subgroups:	Large projects: Size is over than 350 FP 28 People, 2 Basic Units – Large projects Small Projects: Size is less than 350 FP 46 People, 4 Basic Units – less than 350 FP
