Abstract—Reliability as well as validity of an assessment is very important. However, reliability has been frequently overlooked in assessment for supplier selection, while validity has been treated extensively. In this paper, I propose a methodology that can evaluate the reliability of assessment. The well-known gauge R&R study is applied for the purpose. An assessor is able to easily apply the proposed method because the gauge R&R study is very popularin the field. Several case studies show that it is very effective to detect embedded problems could be happen in assessment.
