The problems emerge due to improper process. Giving respond to the problems, a new designed and proposed framework considering all demands in sourcing process is needed to select the best potential supplier, which integrates multivariate approach. The multivariate approach utilizes factor analysis to reduce number of variables, conjoint analysis to understand respondents’ preferences, and multidimensional scaling to visually map the suppliers in a 2-dimensional map. This framework is applied to a case study in PT. XYZ.
