The measurement of international inventory systems

An instrument has been developed to empirically measure the factors (constructs) influencing inventory systems and their effectiveness in international environments. The relevant literature was examined and eight constructs were identified to be included in the scale: the level of infrastructure, government policy, product characteristics, productions environments, supply base, degree of uncertainty, information level and effectiveness of the inventory system. The instrument was tested through structured interviews in operations in North America, South America, Europe and Asia. These scales provide an essential building block for empirical researchers and managers to document the state of international operations. As an example of using this scale a comparison of US, European and Latin American inventory systems is provided.
