In the first stage, the criteria used in the literature were examined. Accordingly, two main criteria are defined as strategic performance and organizational performance. Strategic performance criteria are cost, quality, time, flexibility criteria and related sub-criteria in the evaluation of manufacturing firms. Organizational criteria are the culture, technology and risk criteria that determine the sustainable adaptation between the company and the supplier. Strategic performance criteria and organizational performance criteria consist of 25 sub-criteria. Criterion weights were determined by Analytical Hierarchy Process (AHP) method. According to the findings, the organizational criteria are more important and the most important three criteria can be expressed as Quality Conformity, Technical and Design Capacity, Production Facilities / Capabilities.
