Supply chain vulnerability assessment: A network based visualization and clustering analysis approach
Supply chains are large, complex, and often unpredictable. Purchasing and supply managers and supply chain risk managers need methods and tools to enable them to quickly understand how unexpected disruptions in the supply chain start and grow and to what extent will they negatively impact the flow of goods and services. This paper introduces a methodological approach that can be used by both researchers and managers to quickly visualize a supply chain, map out the propagation path of disruptive events from the supply side to the end customer and understand potential weaknesses in the supply chain design; taking into account the structure, connectivity, and dependence within the supply chain. The approach incorporates a Petri net and Triangularization Clustering Algorithm to offer insights into a supply chain network\u27s vulnerabilities and can be used to efficiently assess supply chain disruption mitigation strategies, especially in complex and difficulty to analyze supply chain systems
Theorizing through metaphorical transfer in OM/SCM research: Divorce as a metaphor for strategic buyerâ supplier relationship dissolution
Operations Management and Supply Chain Management (OM/SCM), as a discipline, can benefit from proper theorizing to address persistent urgings for better and new theories. This paper hopes to inspire more theorizing engagements through the formal process of metaphorical transfer. Metaphorical transfer transforms casuallyâ invoked metaphors in everyday language into theoryâ constitutive metaphors. This transformation process first mandates theorizing to ensure equivalence between the domain of the metaphor and that of a target phenomenon or research problem of interest. Second, theorizing during metaphorical transfer occurs when abstracted insights intended to govern both the metaphor and target phenomenon materialize. Finally, metaphorical transfer supports borrowing of theories from outside of OM/SCM for testing within OM/SCM by safeguarding against common mistakes. This paper demonstrates metaphorical transfer via the example of divorce and strategic buyerâ supplier relationship dissolution and concludes by highlighting other metaphors that may be invoked for a number of exemplary supply chain relationship phenomena.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147073/1/joom579.pd

What characterizes leading companies within business excellence models? An analysis of “EFQM recognized for excellence” recipients in Spain
This paper investigates whether there is a specific approach to the adoption of best management practices embedded in the EFQM Excellence Model, which characterizes leading “Recognized for Excellence” organizations in Spain. In addition, it studies which practices within EFQM’s enablers predict high performance. In contrast to most previous research that used surveys of managers’ perceptions, this study uses the actual criteria and sub-criteria scores attained by organizations in their assessment for EFQM recognition. Scores of a population of 216 organizations, which were assessed in the period from March 2011 to March 2013, are analyzed via ANOVA, factor and regression analyses. The findings show that Spanish organizations adopt the best practices encompassing the EFQM model in a similar fashion: organizations on average follow parallel trends in the scores received per criterion, and there are no significant differences in the importance attributed to enablers. Either role models are being followed, or most organizations know what is expected by the assessors and try to fulfil these expectations. Consequently, an imitative process disseminates and legitimizes the EFQM model in Spain. In addition, it is found that the People criterion makes a difference in attaining high performance, thus emphasizing the relative importance of the softer dimension in Quality Management. This study contributes to the management literature on best practices, by highlighting a consistent trend in the use of the EFQM model, and also provides insights to managers on how to better allocate resources within Business Excellence Models
Coordinating product design, process design, and supply chain design decisions - Part A: Topic motivation, performance implications, and article review process
Despite the undeniable appeal and importance of coordinating decisions across products design, manufacturing process design, and supply chain design to both science and practice, we know very little about how to do so to maximize operational, supply chain, and firm performance. This special issue on Coordinating Product Design, Process Design, and Supply Chain Design Decisions was conceived early 2003 to bring awareness to and to spur scholarly research into this topic. In doing so, we cast a wide net from both content and methodological perspectives, encouraging interdisciplinary papers that were theory-building and/or theory-testing in purpose using either empirical-based (e.g., case research, survey research, historical research, etc.) and/or modeling (i.e., optimization or simulation) methodologies.
The resulting seven papers represent the fruits of this harvest and are being presented in two consecutive parts. Whereas Part A introduces the three papers that speak to the performance implications of coordinating product design, manufacturing process design, and supply chain design decisions, Part B introduces the remaining four papers that address how and why these three decision areas can be coordinated. Included in Part A of this special issue, we also make the review process transparent for third-party evaluation and, more importantly, formally recognize and thank the numerous colleagues from across multiple disciplines and academic institutions around the world for their efforts in helping us produce this two-part special issue

Supply-chain configurations for mass customization
Much of the research on mass customization strategy implementation reflects a functional focus, considering product design, marketing, manufacturing or sourcing, individually. This paper takes a step towards integrating these perspectives into a more systemic view of mass customization strategy implementation. More precisely, the paper explores how a firm's supply chain - meant as the whole of its supply, manufacturing and distribution networks - should be configured when different degrees of customization are offered. The empirical research consists of a multiple case study including firms in the telecommunications, transportation vehicles and food processing equipment industries. Case analyses highlighted that the degrees of freedom customers have in specifying product features, heavily affects the supply-chain configuration, as well as product architecture and, ultimately, firm performances. Our findings further show that two peculiar supply-chain configurations can be identified, each one suggesting an isomorphism between market characteristics, product structure and supply-chain configuratio
Coordinating product design, process design, and supply chain design decisions - Part B. Coordinating approaches, tradeoffs, and future research directions
Complementing Part A which appeared in an earlier issue, Coordinating product design, process design, and supply chain design decisions. Part B. coordinating approaches, tradeoffs, and future research directions introduces four additional papers that belong to this special issue. These four papers seek to provide answers to the following two questions: "What mechanisms allow product design, manufacturing process design, and supply chain design decisions to be coordinated?" and "Why should decisions with respect to product design, manufacturing process design, and supply chain design be coordinated?" Each of the four papers compiled in Part B provides, foremost, an approach to coordinate decisions across the domains of product design, manufacturing process design, and supply chain design. The proposed coordinating mechanisms range from a network-based modeling approach to an assessment procedure for evaluating product architectures to the integration of relevant suppliers into the new product development (NPD) process to a goal programming modeling approach. The fourth paper in Part B, in fact, deploys the proposed goal programming modeling approach to identify and formalize the potential tradeoffs among decisions across the three domains. Part B completes the special issue by identifying future research opportunities, beyond those highlighted within the seven papers that form Part A and Part B of this special issue on Coordinating product design, process design, and supply chain design decisions
