The validity of the SERVQUAL and SERVPERF scales: A meta‐analytic view of 17 years of research across five continents

Abstract: Purpose – The purpose is to investigate, the difference between SERVQUAL and SERVPERF's predictive validity of service qualityDesign/methodology/approach – Data from 17 studies containing 42 effect sizes of the relationships between SERVQUAL or SERVPERF with overall service quality (OSQ) are meta‐analyzedFindings – Overall, SERVQUAL and SERVPERF are equally valid predictors of OSQ Adapting the SERVQUAL scale to the measurement context improves its predictive validity; conversely, the predictive validity of SERVPERF is not improved by context adjustments In addition, measures of services quality gain predictive validity when used in: less individualistic cultures, non‐English speaking countries, and industries with an intermediate level of customization (hotels, rental cars, or banks)Research limitations/implications – No study, that were using non‐adapted scales were conducted outside of the USA making it impossible to disentangle the impact of scale adaptation vs contextual differences on the modera

A Branch-and-Cut Algorithm for a Vendor-Managed Inventory-Routing Problem

Abstract: We consider a distribution problem in which a product has to be shipped from a supplier to several retailers over a given time horizon. Each retailer defines a maximum inventory level. The supplier monitors the inventory of each retailer and determines its replenishment policy, guaranteeing that no stockout occurs at the retailer (vendor-managed inventory policy). Every time a retailer is visited, the quantity delivered by the supplier is such that the maximum inventory level is reached (deterministic order-up-to level policy). Shipments from the supplier to the retailers are performed by a vehicle of given capacity. The problem is to determine for each discrete time instant the quantity to ship to each retailer and the vehicle route. We present a mixed-integer linear programming model and derive new additional valid inequalities used to strengthen the linear relaxation of the model. We implement a branch-and-cut algorithm to solve the model optimally. We then compare the optimal solution of the problem with the optimal solution of two problems obtained by relaxing in different ways the deterministic order-up-to level policy. Computational results are presented on a set of randomly generated problem instances.

Special topic forum on sustainable supply chain management: introduction and reflections on the role of purchasing management*

Abstract: This paper introduces a special topic forum on “Sustainable Supply Chain Management.” Before introducing the papers included in the forum, the authors provide thoughts on the direction and future of sustainability research, particularly in the context of purchasing and supply chain management. The underlying premise that structures our discussion is straightforward: a company is no more sustainable than its supply chain. As such the purchasing function becomes central in a company's sustainability effort. In doing so, we reflect on the relationship between purchasing management and sustainable development by drawing from Kraljic's seminal article on how “Purchasing Must Become Supply Management.”

Conceptualizing the construct of interpersonal conflict

Abstract: The lack of a clear conceptualization and operationalization of the construct of interpersonal conflict makes it difficult to compare the results of different studies and hinders the accumulation of knowledge in the conflict domain. Defining interpersonal conflict as a dynamic process that occurs between interdependent parties as they experience negative emotional reactions to perceived disagreements and interference with the attainment of their goals, the present paper presents a two‐dimensional framework and a typology of interpersonal conflict that incorporates previous conceptualizations of the construct. The first dimension of the framework identifies three properties generally associated with conflict situations: disagreement, negative emotion, and interference. The framework's second dimension identifies two targets of interpersonal conflict encountered in organizational settings: task and interpersonal relationship. Based on this framework, the paper highlights several shortcomings of current conceptualizations and operationalizations of interpersonal conflict in the organizational literature, and provides suggestions for their remedy.
