Using replication research for just‐in‐time purchasing construct development

Abstract Using replication research, the validity of the just‐in‐time purchasing (JITP) construct is established. Although empirical researchers have examined JITP over the last two decades, a consistent set of valid, reliable factors has not been used. The lack of valid construct is a barrier to hypotheses testing and meta‐analyses on JITP. This study confirmed the validity of six JITP factors: top management commitment, employee relations, training, supplier quality management, transportation, and quantities delivered using two different data sets and testing the first‐ and second‐order structure of the JITP construct. Content validity, reliability, unidimensionality, convergent validity, discriminant validity, criterion‐related validity, and an invariant factorial structure of the JITP construct were empirically established.
