Supply chain uncertainty:a review and theoretical foundation for future research

Supply-chain uncertainty is an issue with which every practising manager wrestles, deriving from the increasing complexity of global supply networks. Taking a broad view of supply-chain uncertainty (incorporating supply-chain risk), this paper seeks to review the literature in this area and develop a theoretical foundation for future research. The literature review identifies a comprehensive list of 14 sources of uncertainty, including those that have received much research attention, such as the bullwhip effect, and those more recently described, such as parallel interaction. Approaches to managing these sources of uncertainty are classified into: 10 approaches that seek to reduce uncertainty at its source; and, 11 approaches that seek to cope with it, thereby minimising its impact on performance. Manufacturing strategy theory, including the concepts of alignment and contingency, is then used to develop a model of supply-chain uncertainty, which is populated using the literature review to show alignment between uncertainty sources and management strategies. Future research proposed includes more empirical research in order to further investigate: which uncertainties occur in particular industrial contexts; the impact of appropriate sources/management strategy alignment on performance; and the complex interplay between management strategies and multiple sources of uncertainty (positive or negative)

Supply chain integration strategies in fast evolving industries

Purpose - The purpose of this paper is to define the "fast evolving industry" (FEI) and its supply chain management (SCM) challenges. The authors review and structure the literature regarding integration strategies and implementation methods to develop a strategic decision-making framework for SCM in the FEI. Design/methodology/approach - The authors conduct a review of SCM literature, including supply chain strategy, supply chain integration (SCI), agile and responsive supply chain and SCM for innovative and fast-changing industries. The authors develop a conceptual model and a decision-making framework and use four mini cases to provide support for the model and framework. Findings - The FEI, characterised by a high level of innovation and differentiation, short products/services lifecycle and high variety, is yet to be fully defined. Inherent uncertainty in FEI supply systems makes SCM in these industries a complex but strategic task for their managers. The framework and the model offered in this study, which employ a core competency concept and provide risk management strategies, offer a strategic tool for managers and scholars in the field to optimise their integration strategies and to operationalise integration decisions. Originality/value - Little research has been published on transferable and cross-industrial SCM in FEIs. This paper defines the FEI and its resource-related concerns and then offers a conceptual model and a strategic decision-making framework for SCI in FEIs

In pursuit of supply chain fit

Purpose- The purpose of this paper is to develop exploratory propositions and a conceptual framework on the interaction between organisational structure (decision-making centralisation and internal coordination) and the relationship between supply chain fit and firm performance. Design/methodology/approach- Through a case study, two corporate groups with distinctive organisational structures were examined; both are undergoing a critical moment of changes to their top management and are reshaping their corporate and supply chain strategies. Data on decision-making centralisation, internal coordination mechanisms, supply, demand and innovation uncertainties, and supply chain strategies were collected from key respondents. Findings- The analysis conducted suggests the need to consider the joint interaction between organisational structure and supply chain fit in offsetting the implications of a potential misfit on firm performance. Furthermore, the context sensitivity of a supply chain is often overlooked, hence simply modifying supply chain strategy does not necessarily lead to a variation in firm performance. Practical implications- This research is of particular importance to most organisations in the testing times of uncertainty in the global landscape. It guides supply chain practitioners to better understand which elements of the organisational structure interact with the uncertainty of supply, demand and innovation. Originality/value- This paper is one of the first to investigate the interaction between elements of organisational structure and supply chain fit and identify decision-making centralisation and coordination as the internal uncertainty factors that are most relevant to supply chain fit research. A conceptual framework has been built for future testing, in which the organisational structure moderates the relationship between supply chain fit and firm performance

A Taxonomy of Supply Chain Collaboration

Supply chain collaboration has emerged as an important cooperative strategy leading to new focus on interorganisational boundaries as the determinants of performance. Although collaboration increasingly receives great attention both from practitioners and academics, relatively little attention has been given to systematically reviewing the research literature that has appeared about supply chain collaboration. The purpose of this paper is to examine previous studies on supply chain collaboration based on a taxonomy. The proposed taxonomy is composed of four different research streams of describing specific subjects of interorganisational settings, namely information sharing, business processes, incentive schemes, and performance systems. The analysis includes the assessment of research ideas and key findings. Results show the great variability of key concepts across the four components of the taxonomy and an increased awareness of complementarity amongst research streams. Several recommendations for future research are also identified in this paper. Keywords: supply chain collaboration, literature review, supply chain management, taxonom

Vendor-managed inventory in fresh-food supply chains

This thesis focuses on vendor-managed inventory (VMI) in fresh-food supply chains. VMI is a well-known example of supply chain collaboration, often applied to reduce inventory and improve demand fulfillment in retail supply chains. The thesis shows that VMI is a versatile combination of instruments and can be used in multiple ways to improve the performance of a supply chain. How VMI can be used best depends strongly on the products, processes and organizations of the suppliers involved. Because these characteristics can differ strongly also implementation of VMI can result in different (positive) outcomes. This way, the research emphasizes the importance of allowing suppliers the freedom to really take control of the supply chain. Meanwhile, coaching from the retailer can help to prevent disillusions caused by over or under investment
