Importance-performance analysis (IPA) was prevailed used nowa-days, but it’s not suitable for negative data. When importance data is de-ficient, it is necessary to replace with implicit importance data. So the study discussed theories and analytic methods about several alternative importance-performance analysis, which included revised importance-performance analysis (revised IPA, RIPA), negative importance-perfor-mance analysis (negative IPA, NIPA), importance-performance map analysis based on regression analysis (IPMA-RG) and ridit importance-performance analysis (ridit IPA, RIPA). Based upon SPSS programming, the study proposed some useful programs, and illustrated its applications with practical examples. |
