Abstract:	Six Sigma has already become an efficient improvement technique adopted by a great number of enterprises. Numbers of Sigma has become a tool of measuring process capability in some enterprises. But some of enterprises still use process capability indices (PCIs) to measure the process capability. So numbers of Sigma and PCIs both can be used to measure the process capability. The paper will research the relationship between PCIs and numbers of Sigma. In bilateral specifications, the paper will research the relationship between the PCIs which are Cp, Cpk, Cpm and Cpmk, Spk and numbers of Sigma. In unilateral specifications, the paper will research the relationship between the PCIs which are Cpu and Cpl and numbers of Sigma. If supplier and buyer use different tools to measure the process capability, then the communion bridge to Six Sigma and PCIs can decrease the communicate noise.
