Despite its infancy, some authors are already suggesting that the writing may be on the wall for supply chain collaboration. It has been reported that supply chain collaboration has proved difficult to implement; there has been an over‐reliance on technology in trying to implement it; a failure to understand when and with whom to collaborate; and fundamentally a lack of trust between trading partners. This paper proposes that a supply chain segmentation approach, based on customer buying behaviour and service needs, is the most appropriate context for collaboration. The paper also proposes the need for a greater understanding of the elements that make up supply chain collaboration, and in particular how the relevant cultural, strategic and implementation elements inter‐relate with each other.

With an increasing trend toward using more qualitative case studies, there have been meaningful and significant contributions to the field of operations management, especially in the area of theory building. However, in many of the qualitative case studies we reviewed, sufficient details in research design, data collection, and data analysis were missing. For instance, there are studies that do not offer sampling logic or a description of the analysis through which research outcomes are drawn. Further, research protocols for doing inductive case studies are much better developed compared to the research protocols for doing deductive case studies. Consequently, there is a lack of consistency in the way the case method has been applied. As qualitative researchers, we offer suggestions on how we can improve on what we have done and elevate the level of rigor and consistency.

Although visibility has become a popular buzzword in the supply chain literature it remains an ill-defined and poorly understood concept. It is assumed that if companies across supply chains have visibility of demand, inventory levels, processes, etc., that organizational performance improves. This research explores the antecedents of high levels of supply chain visibility from a resource-based theory perspective across five different external supply chain linkages. We find that the level of visibility across these linkages differs considerably based on various contributing factors which are both technology and non-technology based. Using resource-based theory, we identify those factors that can give a sustainable competitive advantage to a supply chain linkage through a ''distinctive'' or high level of visibility. #

Supply chain integration (or synchronisation) is to a large extent still only a promise, despite many considerable efforts by organisations and their customers and suppliers. Lack of visibility of true consumer demand and collaborative relationships based upon joint decision making remain significant barriers to the goal of supply chain integration. Collaborative planning, forecasting and replenishment (CPFR) is a strategy which promises to overcome these barriers, and seeks through joint planning, joint decision making and the development of a clearer understanding of the dynamics of the supply chain replenishment process to deliver some of the promised benefits of actual supply chain integration. Despite the existence of a detailed and comprehensive process model, and promising initial results there has not been widespread adoption of CPFR, justifying the need to revisit the process model and to further explore the inhibitors and enablers. Based upon a review of the existing literature and a comprehensive survey of participants in existing CPFR implementations, this paper identifies the critical inhibitors and makes some proposals as to how these inhibitors may be overcome.

a b s t r a c tIn their pursuit of improved operational performance, organizations in supply chains have sought to develop external information-based linkages with their customers and vendors. Has this course of action been at the expense of developing similar internal information-based linkages? This research explores the specific roles of internal and external information-based linkages in achieving improved operational performance. Based on a single case study that comprises a supply chain containing twenty-four internal and fourteen external linkages this research develops a series of propositions. We find that the individual internal linkages may be useful for extending externally derived visibility, and for addressing to some extent, "structural holes" in the supply chain. Additionally, to extend visibility across the entire supply chain, organizations need to recognize the combining role of internal and external information-based linkages. Finally we offer some thoughts for future research in this area.

PurposeThe purpose of this paper is to introduce and validate two new constructs with the potential to sharpen our understanding of how and why firms integrate their internal supply chains and assess the governance structure of their supply chains. The first construct, organizational alignment (OA), is a reflective scale measuring the extent to which upper management attempts to foster integration between internal supply chain functions. The second, supply chain governance structure (SCGS), is a formative index, and is a first attempt at developing a measurement instrument to assess SCGS along multiple dimensions.Design/methodology/approachFollowing a literature review, measures of OA and SCGS are conceptualized. These instruments are used to collect data, after which they are refined and validated through parallel scale development (OA) and index construction (SCGS) processes.FindingsOA shows acceptable content and construct validity, and SCGS shows acceptable results for content and item specification, as well as multicollinearity.Practical implicationsOA and SCGS may provide some insight into how to promote better internal supply chain integration within the firm, and may allow for an assessment of the governance structure of the firm's supply chain. In different industries and at different times, this knowledge may prove useful in supply chain design and supply base optimization decisions.Originality/valueThese scales have considerable applicability in logistics and supply chain management research. Together, they represent initial attempts to assess upper management influence on internal supply chain alignment (OA), and to assess the governance structure of a firm's supply chain.

Supply chain integration is to a large extent still only a promise, despite considerable efforts by organizations and their customers and suppliers. Lack of visibility across the supply chain together with adversarial relationships between members are significant barriers to supply chain integration. Collaborative planning, originating from the consumer packaged goods industry, is an approach that promises to overcome these barriers, and through join planning and development of a clearer understanding of the dynamics of the supply chain replenishment process to deliver some of the promised benefits of supply chain integration. To help position the concept of collaborative planning, various collaborative initiatives such as vendor‐managed inventory (VMI) and continuous replenishment (CR) and collaborative planning (CP) are reviewed. The evolution and the value of various collaborative planning initiatives are presented as well as how these initiatives are positioned within the overarching concept of supply chain management. Finally, a future research agenda is suggested.
