Abstract

Purpose

This study aims to examine publications of supply chain management (SCM) researchers from across the world and maps the leadership role of authors and institutions based on how prolific they are in publishing and on network measures of centrality while accounting for the quality of the outlets that they publish in. It aims to inform stakeholders on who the leading SCM scholars are, their primary areas of SCM research, their publication profiles and the nature of their networks. It also identifies and informs on the leading SCM research institutions of the world and where leadership in specific areas of SCM research is emerging from.

Design/methodology/approach

Based on SCM papers appearing in a set of seven leading journals over the 15-year period of 2001-2015, publication scores and social network analysis measures of total degree centrality and Bonacich power centrality are used to identify the highest ranked agents in SCM research overall, as well as in some specific areas of SCM research. Social network analysis is also used to examine the nature and scope of the networks of the ranked agents and where leadership in SCM research is emerging from.

Findings

Authors and institutions from the USA and UK are found to dominate much of the rankings in SCM research both by publication score and social network analysis measures of centrality. In examining the networks of the very top authors and institutions of the world, their networks are found to be more inward-looking (country-centric) than outward-looking (globally dispersed). Further, researchers in Europe and Asia alike are found to exhibit significant continental inclinations in their network formations with researchers in Europe displaying greater propensity to collaborate with their European-based counterparts and researchers in Asia with their Asian-based counterparts. Also, from among the journals, Supply Chain Management: An International Journal is found to exhibit a far more expansive global reach than any of the other journals.

Research limitations/implications

The journal set used in this study, though representative of high-quality SCM research outlets, is not exhaustive of all potential outlets that publish SCM research. Further, the measure of quality that this study assigns to the various publications is based solely on a publication score that accounts for the quality of the journals, as rated by Association of Business Schools that the papers appear in and nothing else.

Practical implications

By informing the community of stakeholders of SCM research about the top-ranked SCM authors, institutions and countries of the world, the nature of their networks, as well as what the primary areas of SCM research of the leading authors in the world are, this research provides stakeholders, including managers, researchers and students, information that is helpful to them not only because of the insights it provides but also for the gauging of potential for embedding themselves in specific networks, engaging in collaborative research with the leading agents or pursuing educational opportunities with them.

Originality/value

This research is the first of its kind to identify and rank the top SCM authors and institutions from across the world using a representative set of seven leading SCM and primary OM journals based on publication scores and social network measures of centrality. The research is also the first of its kind to identify and rank the top authors and institutions within specific areas of SCM research and to identify future research opportunities relating to aspects of collaboration and networking in research endeavors.

Abstract

Notes that after‐sales field service has become an established competitive differentiator among equipment manufacturers. From the service provider’s perspective, effective field service management is essential for operational productivity, customer satisfaction and retention, and profitability. Benchmarking is a process for measuring a firm’s performance against the best‐in‐class, and using such an analysis to meet or exceed the best‐in‐class performance. Develops a benchmarking approach that utilizes customer satisfaction survey results in conjunction with a zero defects metric. The applicability of this method is demonstrated through its use in competitive and internal benchmarking of equipment field services in the case of a European office‐equipment manufacturer.

Abstract

Six sigma is a way to measure the probability of manufacturing a product or creating a service with zero defects. Presents a case study to illustrate how the concept of zero defects, measured by six sigma, can be applied to customer satisfaction measurement and to examine the impact of customer expectations on the company’s strategies for improving satisfaction. The information presented is based on actual studies conducted for a high‐tech manufacturing company in the USA during 1991 and 1992. The performance and expectations values and some of the attributes have been altered for reasons of confidentiality.

Abstract

Effective measurement and analysis of service quality are an essential first step in its improvement. This paper discusses the development of neural network models for this purpose. A valid neural network model for service quality is initially developed. Customer data from a SERVQUAL survey at an auto‐dealership network in The Netherlands provide the basis for model development. Different definitions of service quality measurement are modelled using the neural network approach. The perception‐minus‐expectation model of service quality was found not to be as accurate as the perception‐only model in predicting service quality. While this is consistent with the literature, this study also shows that the more intuitively appealing but mathematically less convenient expectation‐minus‐perception model out‐performs all the other service quality measurement models. The study also provides an analytical basis for the importance of expectation in the measurement of service quality. However, the study demonstrates the need for further study before neural network models may be effectively used for sensitivity analyses involving specific dimensions of service quality.

Abstract

Purpose

The purpose of this paper is to examine the leadership role of authors, institutions, and countries based on research co-authorship networks in the field of operations management (OM) and ranks European authors, institutions, and countries using network centrality measures. It also identifies the primary research areas of each of the leading European authors and maps the areas that European research in general has focussed most on.

Design/methodology/approach

Based on co-authorships in publications appearing in a representative set of three leading OM journals over the 15-year period of 1998-2012, network measures of total degree centrality and betweenness centrality are used to identify influential European agents serving as leaders and bridge builders in OM research. Keyword analysis is used to identify the dominant areas of OM research in Europe as well as the primary areas of research of the leading authors.

Findings

With UK, Spain, The Netherlands, and Italy accounting for the dominant share of authorship of papers in the journal set, many authors and institutions from these countries are also found to rank high on network centrality measures. While certain authors, institutions, and countries are found ranking high on total degree centrality based on number of direct connections in the network, others are found to play uniquely important roles as gatekeepers and bridge builders in network relationships. The body of research is found to be focussed most on the area of supply chain management. It is also found to be focussed more on manufacturing than service.

Research limitations/implications

The examination of networks in this study based on co-authorships in publications in the set of three leading journals: Journal of Operations Management, International Journal of Operations & Production Management, and Production and Operations Management, is not all encompassing as there are likely other co-authorship relationships of OM researchers that go beyond publications in this set of journals.

Practical implications

Co-authorship of papers in the leading academic journals in a discipline provides a window on patterns of collaboration among key researchers within that academic community. The findings of this study inform the community of stakeholders on who the leading European agents in OM research are, what the primary areas of research of the leading European authors are, and areas that European research has focussed most on.

Originality/value

This is the first study of its kind that identifies and maps key European authors, institutions, and countries based on the analysis of co-authorship networks of researchers who have published in a set of leading OM journals that are considered to be among the most relevant outlets in the field of OM. It also maps the primary areas of research.

Abstract

Theory building efforts in quality management have begun in earnest. However, while services continue to dominate the developed economies of the world, these studies have mostly focused on manufacturing firms. Research that addresses this limitation by specifically addressing quality management in service organizations is presented in this paper. Through a survey of 170 US service firms, this study empirically develops and validates 11 constructs for quality management in services. A comparison between this study and other empirical quality management studies highlights many distinct quality management constructs in services. It also shows that all empirical studies have some gaps in the coverage of their constructs, reiterating the need for continued quality management theory building research in services and manufacturing.

Abstract

This article discusses the unmet need for widespread certification and professionalization of those involved in public procurement. Through original data analysis, differences in perceptions regarding the value and benefits of certification among public sector procurement practitioners are examined. Findings indicate that there is growing awareness by both those holding certification and those who are not certified that certification leads to advanced knowledge and skills within the procurement area. Further, job advancement and occupational growth is perceived to be directly related to certification, and that certification holders enjoy special privilege within occupational norms.

Abstract

It is not sufficient for firms to deliver products that have technical excellence. Products should be easy to use and fit in with the work practices, activities and context of the consumer. Product usability is now recognized as a critical dimension of product quality. Product usability is defined by product attributes that address the physical, cognitive and emotional needs of intended users. Based on a database of documented real‐world customer experiences with manufactured products in use, this research maps the categories of product usability using an affinity diagram. The resulting affinity diagram and the insights it provides can help managers design products that better meet the needs of their customers. Limitations of the study and the implications of its findings are also discussed.

Abstract

Purpose

A growing need for global sourcing of business has subjected firms to higher levels of uncertainty and increased risk of supply disruption. Differences in industry and infrastructure make it more difficult for firms to manage supply disruption risks effectively. The purpose of this paper is to extend developing research in this area by addressing gaps within existing literature related to environmental turbulence and uncertainties.

Design/methodology/approach

The authors test the model using data collected from 253 senior managers and directors in the Thai beverage industry using advanced statistical techniques to explore the relationship between representations of supply disruption risk and uncertainty.

Findings

The results show that both magnitude and probability of risk impact on the disruption risk, but the probability of loss is a dominant determinant. The authors also find that demand uncertainty and quality uncertainty affect the risk perception of purchasing managers, and are related to the magnitude of disruption risk, rather than the frequency of occurrence. Interestingly, the results show that quality uncertainty negatively impacts on the severity of disruption risk.

Research limitations/implications

The construct validity of demand uncertainty was under the required threshold, intimating the need for further construct development.

Practical implications

The framework provides managers with direction on how to formulate and target their disruption risk management strategies. The work also allows practitioners to critical reflect on implicit risk management strategies they may already employ and their effectiveness.

Originality/value

The paper identifies key antecedents of supply disruption risk and tests them within a novel industrial context of the beverage industry and a novel national context of Thailand.

Abstract

Purpose

The main aim of the present study is to explore field of Six Sigma and discover the limitation of the present research work. The study also tries to find emerging aspects, trends and future directions and explore unfocused areas of Six Sigma. The present study involves an analysis of 179 research articles published from 1995 to 2011 in 52 selected reputable journals.

Design/methodology/approach

The methodology of critical assessment involves selection and classification of 179 research articles on Six Sigma. The selected articles are classified by: time distribution of articles, research methodology, research stream, authorship patterns, sector-wise focus of articles, integration with other manufacturing philosophies, implementation status and performance measurement of the models or framework. Then, the suggestions for the future scope of research possibilities and development are identified.

Findings

The study provides a taxonomical and integrated review of articles. Further, this study provides perspectives on conceptualization and various critical parameters for research. Through this literature review, many issues are addressed which have not previously been adequately covered. The findings include: increase in empirical nature of research articles, need for spreading research in the field of Six Sigma implementation, need for more interregional research collaborations, need for integration of Six Sigma philosophy with other philosophies and lack of implementation, i.e. testing and validation of the proposed models or frameworks by researchers.

Practical implications

The present study has explored an unfocused area of Six Sigma which will help future researchers to concentrate on the grey areas of Six Sigma. The study will help professionals to get a comprehensive database of Six Sigma articles and their use in practical situation. The results obtained from the study are expected to help researchers, academics and professionals to focus on the growth, pertinence and research developments to implement Six Sigma principles.

Originality/value

This paper will be of great help for those carrying out research in Six Sigma field including academics and practitioners in terms of Six Sigma growth describing the trends, sources and findings. The unique feature of this research is the large sample size and a time span of 16 years (1995-2011).
