About “strategy” and “strategies” in supply management

This article addresses the context and content of a generic supply strategy and discusses its strategy-making process. Building mostly on fundamental strategic management theories, the authors explain the role of supply strategy in its managerial context. In so doing, some light is shed on the meaning and use of the terms “strategy” and “strategies”. Also, a practical conceptual framework for supply strategy formulation is provided. The generic checklist, built by segmenting supply management decisions, is intended to guide supply professionals in addressing strategic issues to create value to customers, avoiding confusion and optimising resource allocation.     

Levels of strategic purchasing: Impact on supply integration and performance

The growing importance of supply chain management has led to an increasing recognition of the strategic role of purchasing, which has recently evolved and expanded from “buying” to “procurement” and “supply management”. In this study, we chart our sample firms’ advance in strategic purchasing, characterized by the strategic focus, strategic involvement of the purchasing function and the status and visibility of the purchasing professionals, into three stages.This study provides strong empirical support for the importance of strategic purchasing by showing that, by moving towards the more advanced stages, firms at the nascent stage of strategic purchasing can achieve better supply integration, a second-order construct composed of four facets of relational, process, information, and cross-organizational team integration. Our analyses further reveal that strategic purchasing can have a profound impact on supply chain performance for both buyer and supplier firms.     

Evaluation of factors affecting strategic supply chain network design

The design of a supply chain network lies at the core of supply chain management, and it is affected by many variables corresponding to several factor groups. This study evaluated the importance of such influencing factors, namely, political and social characteristics, supply characteristics, product characteristics, demand characteristics, and service requirements, for evaluating strategic location alternatives in a supply chain system. A structural equation modelling approach was employed to analyse the effects of these factors. Results indicated that supply characteristics, product characteristics, demand characteristics, and service requirements positively affect strategic supply chain network design. The influence of the political and social factor group on strategic location alternatives was not supported in this study. Theoretical and managerial implications of the findings are discussed and potential research directions are proposed.     

The role of supply management innovativeness and supplier orientation in firms’ sustainability performance

Questions about the influencing factors and measurement of firms' sustainability performance have attracted growing research interest, as the requirements for sustainability have steadily increased. This study examines whether supply management innovativeness and supplier orientation make positive impacts on firms' overall sustainability performance. An empirical study based on a survey targeting large- and medium-sized manufacturing companies in Finland shows that innovativeness in supply management considerably influences a firm's overall sustainability performance and that supplier orientation positively relates to sustainability performance. The benefits of innovativeness in supply management and strategic supplier orientation are directly realised in sustainability performance. Therefore, supply management is not only a gatekeeper against sustainability risks arising from the supply base but is also a function by which new ideas aiming to influence supply markets and firms' sustainability are presented.     

Evaluation of supplier capability and performance: A method for supply base reduction

Development of partnership with suppliers is widely recognised today as a potent tool for supply chain improvement. To develop an effective partnership, it is necessary to have a small supply base and an effort to reduce the supply base to a manageable level. Despite its overwhelming importance, models of supply base reduction are rare. Supplier sorting methods, used for pre-selection of suppliers and sometimes seen as methods for supply base reduction, have limitations ranging from (1) requirement of an exhaustive database of historical information (case-based reasoning), (2) inability to predefine the number of elements in a cluster (cluster analysis) and (3) inability to identify suppliers who are both highly capable as well as high performers (data envelopment analysis). In the present work, we develop a systematic framework for carrying out the supply base reduction process. The study assumes two important dimensions of suppliers—performance and capability. Performance of a supplier represents short-term effects on the achievement of supply chain objectives while supplier capability indicates long-term effects. Many of the performance and capability factors are imprecise in nature. In order to account for the imprecision involved in numerous subjective characteristics of suppliers, we use fuzzy set approach to measure the imprecision of these factors and rank a potential list of suppliers against their performance and capability. We then display their ranks in a ‘capability–performance matrix’ that helps a decision maker arrange the suppliers in decreasing order of preference. The desired numbers of suppliers are finally selected on the basis of this ordered list. The suggested framework will be of immense help to the practising managers in reducing the supply base—a prerequisite for building a strong supplier partnership and developing an effective supply chain.     

Outsourcing occupational safety and health: An analysis of the make or buy decision

This paper investigates the factors affecting the outsourcing decision of occupational safety and health (OSH) services. I posit several hypotheses following the three main approaches to the make or buy question: (1) the transaction cost theory, (2) the resource‐based view of the firm, and (3) the behavioral decision‐making framework. The empirical analysis draws on microdata from 3,047 Spanish firms that are legally obliged to provide organized OSH activities but free to choose the option to outsource. Results show that informational symmetries and increasing transaction costs mainly explain the decision to outsource the OSH activity. Organizational behavior variables, such as management commitment to safety and workers' representation, also relate to the outcome of the decision but not necessarily as hypothesized. Finally, I did not generally observe the strategic value of safety in informing the make or buy decision. © 2009 Wiley Periodicals, Inc.     

Cognitive Biases and Strategic Decision Processes: An Integrative Perspective

Previous studies have not adequately addressed the role of cognitive biases in strategic decision processes. In this article we suggest that cognitive biases are systematically associated with strategic decision processes. Different decision processes tend to accentuate particular types of cognitive bias. We develop an integrative framework to explore the presence of four basic types of cognitive bias under five different modes of decision making. The cognitive biases include prior hypotheses and focusing on limited targets, exposure to limited alternatives, insensitivity to outcome probabilities and illusion of manageability. The five modes of strategic decision making are rational, avoidance, logical incrementalist, political and garbage can. We suggest a number of key propositions to facilitate empirical testing of the various contingent relationships implicit in the framework. Lastly, we discuss the implications of this framework for research and managerial practice.     

Vendor managed inventory: a survey of the Taiwanese grocery industry

Recent research has shown the importance of improving the supply chain competitiveness by means of strategic alliances. This study considers the retailer–supplier partnership through a vendor managed inventory (VMI) system. The characteristics of a VMI system and a retailer–supplier power relationship are discussed in some detail with a case illustration to examine the practical implementations of the system in the Taiwanese grocery industry. VMI not only has the ability to reduce costs, but also to improve service levels and create business opportunities for both parties in the supply chain. Thus, it is considered as one of the main systems in a strategic alliance.

Strategic supply management: The relationship between supply management practices, strategic orientation and their impact on organisational performance

A theoretical model is presented for conceptualising the relationship between the management of supply, strategic orientation at the business-unit level and their proposed link with firm performance. The shortcomings of existing approaches in accounting for the wide variety of purchasing practices in a comprehensive supply management framework are discussed as well their alignment with strategic orientation. The paper concludes by presenting a model and propositions concerning firm-level supply management, strategic orientation and firm performance.     

B2B seller competence: Construct development and measurement using a supply chain strategy lens

In less than a decade, Internet-enabled business-to-business (B2B) commerce has become central to supply chain management. But little is known about the infrastructural competencies required for manufacturers engaged in Internet-enabled activities with downstream business customers. This paper aims to take a first step in operationalizing a set of new, multi-item measures that tap into infrastructural (or “soft”) competencies required for leveraging B2B commerce.We use a structured, two-stage approach to develop and refine a set of constructs, items, and new multi-item measurement scales in order to rigorously evaluate their measurement properties. By drawing upon the literature as well as extensive interviews with expert practitioners, we define and measure the salient infrastructural competencies – termed B2B seller competence (B2B-SC) – associated with the seller-side of Internet-enabled commerce. We find that the conceptual domain of B2B-SC comprises seven theoretically important dimensions: (1) technical skills, (2) change disposition, (3) conflict management, (4) market acuity, (5) coordinated logistics, (6) knowledge channels, and (7) fluid partnering. Operational indicators that tap into constructs pertaining to each B2B-SC dimension are developed through an iterative process.In the second stage, we conduct a field study to more fully assess the measurement properties of item and scale reliability and validity using a covariance structure framework. The results indicate that our new scales exhibit sufficient psychometric properties, which make them useful for theory building, testing, and the refinement of supply chain strategy paradigms in the emerging area of B2B commerce.     

Managing the global supply base through purchasing portfolio management

‘How to source globally’ has become a critical strategic decision for companies competing on a global basis. Despite an increased focus on global sourcing and supply chain management, little is known about the challenges and solutions surrounding such sourcing practices. Extant literature points at the critical importance of developing and sharing knowledge in multinational companies (MNCs). However, little work has been undertaken to examine the organizational mechanisms used by MNC headquarters for knowledge leveraging across subsidiaries, especially in the area of purchasing and supply management. Based on an in-depth case study, focusing on a chemical company, the actual buying systems for managing the global supply base are explored. Kraljic's purchasing portfolio approach appears useful, both for developing effective purchasing strategies as well as for managing a global supply base.     

At the receiving end of supply network intervention: The view from an automotive first tier supplier

As companies are increasingly responsible for all ingredients that make up their products, the requirement to increase visibility and exert control over the entire supply network has been identified as key imperatives. However, little research to date has examined the consequences of supply network control on the suppliers that are at the receiving end of it. This paper reports on research into the dynamics of supply network intervention and the effects on the companies that are subject to attempts to control a supply network, particularly in the context of new product development. The paper discusses the case of an automotive component supplier and its role in a specific vehicle development project. The case study shows how the supplier was a victim of its customer's attempt to ‘supply chain manage’ the project, giving the supplier little control over key activities such as the choice of suppliers of key components and little influence on commercial and technical agreements. The perspectives of both vehicle manufacturer and supplier are debated to reveal the drivers for and problems associated with supply network intervention. The paper discusses the theoretical and managerial implications of the study and concludes by raising some serious questions about the negative effects of intervention strategies.     

Managing business processes across supply networks: the role of coordination mechanisms

The theory of network coordination provides a theoretical basis to explain how companies can overcome organizational boundaries and constraints to jointly manage business processes across supply networks. In particular, this paper focuses on Collaborative Planning, Forecasting and Replenishment (CPFR), a collaboration process whereby supply chain trading partners activate inter-firm coordination mechanisms to jointly plan key supply chain activities, from production and delivery of raw materials to production and delivery of final products to end customers.By discussing three case studies of CPFR implementation in supply networks of different industries–i.e. pharmaceutical, automotive and mechanical–the paper provides a theoretical framework that contributes to explaining the relations between inter-firm coordination mechanisms and the characteristics of interdependence among the actors involved in CPFR implementation.     

Explicit filters and supply chain design

Due to the complexity of present day supply chains it is important to select the simplest supply chain scheduling decision support system (DSS) which will determine and place orders satisfactorily. We propose to use a generic design framework, termed the explicit filter methodology, to achieve this objective. In doing so we compare the explicit filter approach to the implicit filter approach utilised in previous OR research the latter focusing on minimising a cost function. Although the eventual results may well be similar with both approaches it is much clearer to the designer, both why and how, an ordering system will reduce the Bullwhip effect via the explicit filter approach. The “explicit filter” approach produces a range of DSS designs corresponding to best practice. These may be “mixed and matched” to generate a number of competitive delivery pipelines to suit the specific business scenario.     

Analysis and design of focused demand chains

The paper describes the evolution of focused demand chains over an extended period of time as a major UK lighting manufacturer has sought to remain an international player in a fast changing business environment. Analysis and design procedures make use of the concepts of Wickham Skinner and Marshall Fisher to answer the strategic questions “what facilities are required and how should they be laid out to enable the necessary focused demand chains?” and to answer the tactical question “which focused demand chain is appropriate for this product?” The case study then details how the company has been transformed from operating within a traditional supply chain to driving change via the engineering of four focused demand chains. The paper concludes with a comparison of operations enablers, customer choice, and business performance metrics covering the transition period culminating in the current focused demand chain scenario. By matching products to the appropriate value stream there is a consequential reduction in product development time of 75%; manufacturing costs reduction of up to 27%; and up to 95% reduction in delivery lead times.     

Does relationship learning lead to relationship value? A cross-national supply chain investigation

In global business-to-business markets, shared resources between buyers and suppliers often result in competitive advantages and enhanced relationships between firms. Unfortunately, there is a paucity of research regarding learning capabilities between business partners in a cross-border setting. This study takes the approach to integrate customer value literature into interorganizational learning theory and adopts the often-neglected theoretical perspective of transaction value by contextualizing inter-firm collaboration in terms of relationship learning and value co-creation viewed by both the buyers and sellers in one single study. Through the development of a conceptual framework that examines how global environmental and inter-organizational conditions influence learning capabilities, the study investigates how relationship learning influences relationship value for both supplying and buying firms. Using a survey of 126 cross-border dyads in the industrial chemical, packaging, consumer durable, and apparel industries, the authors show how relationship learning is valued by both buyers and suppliers, and how it is critical when viewing the “supplier as a customer.” The results indicate the strategic nature of relationship learning in maintaining cross-border business-to-business relationships. Simultaneously, the findings provide evidence that cultural distance is not a significant influence on the firm's propensity to share knowledge with its global partners. It helps advance our understanding of the significance of cultural-pollination in the era of globalization.     

Optimizing the credit term decisions in supply chain finance

We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting.     

Learning, communication, and the bullwhip effect

We investigate the effect of learning and communication on the bullwhip effect in supply chains. Using the beer distribution game in a controlled laboratory setting, we test four behavioral hypotheses – bounded rationality, experiential learning, systems learning, and organizational learning – by systematically manipulating training and communication protocols. We find that order variability decreases significantly in a setting in which participants start with hands-on experience, and are then allowed to formulate team strategies collaboratively. This result indicates that while training may improve individuals’ knowledge and understanding of the system, it does not improve supply chain performance unless supply chain partners are allowed to communicate and share this knowledge. Our results indicate that the bullwhip effect is, at least in part, caused by insufficient coordination between supply chain partners.     

The effects of innovation–cost strategy, knowledge, and action in the supply chain on firm performance

Despite the importance of supply chains within today's economy, we know little about how the knowledge of supply chains can contribute to superior performance at the firm level. Building on the resource-based view, knowledge-based view and strategic choice theory, we develop hypotheses linking two knowledge-driven supply chain phenomena (i.e., knowledge development capacity and intellectual capital), innovation–cost strategy, and action to firm-level performance. Using survey and archival data from 489 firms, we found that performance is influenced by how well knowledge development capacity and intellectual capital efforts complement alternative chain strategies. More specifically, each strategy type requires different constellations of knowledge development capacity and intellectual capital to enhance action and create superior firm performance. These results highlight the importance of supply chain phenomena for firm-level performance, and more broadly, the value of supply chains as a competitive weapon in contemporary firms.
