This study suggests a method that transfers the House Of Quality (HOQ) approach typical of Quality Function Deployment (QFD) problems to the ERP software selection process. To test its efficacy, the method is applied to an ERP software selection process for an assembling company that manufactures engine of automobiles. The study starts by identifying the features that the ERP system should have (WHATs) in order to satisfy the companys needs, then it seeks to establish the relevant ERP systems criteria (HOWs) in order to come up with a final ranking based on the fuzzy suitability index (FSI). The whole procedure was implemented using fuzzy numbers; the application of a fuzzy algorithm allowed the company to define by means of linguistic variables the relative importance of the WHAT, the HOW-WHAT correlation scores, the resulting weights of the HOW and the impact of each potential ERP software. Special attention is paid to the various subjective assessments in the HOQ process and symmetrical triangular fuzzy numbers are suggested to capture the vagueness in peoples verbal assessments.]]>Akao, Y.,1990Badri, M.A., D.
