Vendor Managed Inventory: why you need to talk to your supplier

Purpose The purpose of this paper is to investigate the concept of Vendor Managed Inventory (VMI) from an inter-organisational perspective. Extant literature on VMI tends to investigate the concept from a focal perspective, even though VMI has originally been born as a collaborative arrangement. Design/methodology/approach The paper is based on a literature review and an empirical study. It provides a comprehensive literature review on VMI and an illustrative case study of a supplier and a buyer jointly implementing VMI. Findings The findings of this paper are twofold. First, a literature review uncovers that contemporary research has delimited the analysis of VMI to a focal company perspective as current VMI cost models tend not to capture the picture of the complete supply chain. Second, it demonstrates through an illustrative case study that adoption of an inter-organisational approach to VMI is vital if companies are to optimize their buyer-supplier relationships. Research limitations/implications Future research should test the implications proposed in the empirical section, as this piece of research can be seen as exploratory case study research with the aim of analytical generalizations. Practical implications The inter-organisational VMI cost perspective in supply chains should be emphasized in purchasing departments since such a perspective significantly raises the awareness of the costs incurred in a supply chain. Originality/value Existing research has not explicitly focused on inter-organisational costs incurred by companies implementing VMI. This study seeks to bridge this research gapPeer Reviewe

A dark side of long-term VMI relationships: supply chain trust

Supply chain management literature is rich in pointing to the benefits generated by collaborative supply chain arrangements. While there is consensus that supply chain integration can improve supply chain performance, research studying relational factors in long-term collaborative buyer-supplier relationships is still scarce. Focusing on distributor-manufacturer relationships that use VMI, and based on the theory of psychological contracts, this paper investigates the relationship between the length of a VMI relationship and the supply chain trust in that relationship using survey data. While our findings confirm that average distributor trust in the manufacturer is quite high, we also shed light on a dark side of long-term VMI relationships by providing evidence that they are associated with lower levels of distributor trust in the manufacturer (relative to short-term relationships). Our findings demonstrate that in order to maintain the initially high trust levels in VMI relationships, good inventory performance may not be sufficient

The Role of Innovation in Inventory Turnover Performance

How a firm utilizes technological innovation to improve operations management is an important research question in today's knowledge economy but lacks empirical evidence in the literature. We use a dataset of all non-service U.S. public firms from 1976 to 2005 to examine how a firm's innovation performance is associated with its inventory turnover performance. In particular, we measure a firm's innovation performance by the ratio of its patents (either citations or counts) to its research and development (R&D) expenditure. Our fixed-effect panel regression results indicate a positive relation between innovation performance and inventory turnover ratio, and such a relation varies across industries. By differentiating process and product innovation according to patent usages, we find that process innovation has a consistent and long-lasting effect, whereas product innovation has an immediate but short-lasting effect. We also find supporting evidence for industry spillovers by showing that firms in a more innovative industry are likely to better manage their inventory performance. Our results confirm the benefit of using innovation in logistics and operations management and point to the strategic importance of integrating technology and operations management.postprin

An investigation of the effects of IT investment on firm performance: The role of complementarity.

The concept of complementarity has been introduced into IT-based firm performance research in order to address inconsistent magnitudes of the impacts from IT investments across studies. This dissertation seeks to understand the scope of IT investment complementarities, to examine the different ways in which different complementarities impact the payoff from an IT investment, and to empirically test the effects of complementary investments in the context of investments in SCM and CRM. The knowledge-based view of the firm (KBV) is employed in order to understand a boundary and different roles of complementarity. The KBV sees organizational capabilities from the aggregation of knowledge into capabilities and the deployment of knowledge assets in the form of capabilities. Knowledge aggregation requires individuals' specialized knowledge (human capital) and the aggregation mechanisms of structural, social, and community capital. The combination of these three forms of capital, together with human capital, constitutes organizational capabilities. Once constituted, the complementary deployment of capabilities is important. Foundational capability must be in place in order for the focal IT investment to deliver value, synergistic capability amplifies the economic benefits of the focal IT investment, and management capability is managers' organizing vision and capability to successfully deploy the focal IT investment.The research findings show that three forms of structural, community, and human capital have highly significant impacts on firm performance measured by Net Cash Flow, Gross Profit, and EBITDA. Synergistic capabilities and management capabilities are found to be highly significant in moderating between three forms of capital and firm performance measurements.The data for this study were drawn from secondary data sources: Annual Reports, Press Releases, and news articles. The dependent variables are drawn from COMPUSTAT. The data collection method for the independent variables was a keyword search. The research sampling frame is confined within a single value chain however distinctively different industry categories are represented within this value chain. This sampling strategy yielded a total of 111 firms that had invested in SCM and 45 firms that had invested in CRM

Decision support models for supplier development: Systematic literature review and research agenda

The continuing trend towards sourcing components and semi-finished goods for less vertically integrated manufacturing systems globally leads to a dramatic increase in supply options for companies. To ensure that companies benefit from the potentials global sourcing offers, supplier-buyer relationships need to be managed efficiently. Due to the decreasing share of value-adding activities provided in-house, suppliers are more and more considered as an essential contributor to the buying company's competitive position. Consequently, to realize and sustain competitive advantages, companies try to establish institutionalized long-term relationships to their most important suppliers and to actively improve the productivity and performance of their supplier base. To support supplier development in practice, researchers have developed decision support models that provide assistance in selecting and implementing suitable supplier development activities. The aim of this paper is to provide a comprehensive and systematic overview of decision support models for supplier development and to develop a research agenda that helps to identify promising areas for future research in this area. First, typical applications for supplier development as well as potential development measures that can be adopted to improve the performance of suppliers are identified. Secondly, a systematic literature review with a focus on decision support models for supplier development is conducted. Based on the analysis of the literature, we define a research agenda that synthesizes key trends and promising research opportunities and thus highlight areas where more decision support models are needed to foster supplier development initiatives in practice

The Nature and Characteristics of Production Networks in East Asia: Evidences from Micro/Panel Data Analyses

Production networks in East Asia, particularly being extended by machinery industries, have presented unprecedented development with their significance in economies in the region, their geographical extension, and their sophistication in combining intra-firm and arm's length transactions. In particular, the fragmentation of production activities together with the formation of industrial agglomerations in developing countries is a novel phenomenon that would lead to an East Asian model of economic development. Starting from a brief review of our conceptual framework based on the fragmentation theory as well as an empirical overview with international trade statistics and others, the paper presents a survey on empirical evidences that have been established by previous micro-data analyses in East Asia and discusses a list of empirical issues that future studies should explore. Topics include (i) the selection of exporters and investors, (ii) organizational structure and spatial design of production networks, (iii) location choice, (iv) impacts of outward FDI on developed countries, and (v) learning and impacts of inward FDI on LDCs.

Exploring Customers\u27 Perceptions of Third Party Maintenance, Repair, and Operating Programs

A survey of 25 industrial manufacturing organizations in the U. S. indicated that 70% of respondents experienced dissatisfaction with their outsourcing programs due to unfulfilled expectations, which caused negative continuance intentions. The purpose of this descriptive case study was to explore the experiences of customers who currently use 3PMRO outsourcing programs to determine what factors affect satisfaction levels in the Southern United States. The conceptual framework for this study was the expectancy disconfirmation paradigm, which connects consumer satisfaction level to the fulfillment of consumer expectations. Data were collected from interviews of 22 procurement professionals of maintenance, repair, and operating supplies; observations of 3PMRO supplier performance meetings; and the analysis of performance scorecard documents. Data were analyzed using pattern matching followed by thematic analysis. Three themes were identified through the data analysis that affected consumer satisfaction: inventory management services, utilization of outsourced labor resources, and total cost value of the 3PMRO program. According to results, satisfaction of 3PMRO consumers are based on the proper utilization of a 3PMRO program for the intended limitations of the organization, reduced MRO supply costs, improved inventory management strategies, and improved competitive advantage from the realignment of resources to focus on core competencies. Implications for positive social change include increased awareness of cradle-to-grave inventory management to prevent improper disposal of non-biodegradable materials into our environment

Three Essays on Innovation and Regional Economic Development

The first essay develops a typology that identifies the multiple pathways, functions and operations where innovation can occur in a firm\u27s internal business cycle based upon the extant literature that includes both technological and non-technological activities. This is an important step toward developing a comprehensive strategy for a regional economy and provides a common platform for the discussion of innovation among academics and practitioners.The typology adds to the existing knowledge of how innovation works in organizations by describing the pathways, business functions and operations in a firm\u27s internal-business-process the business strategies used to advance innovation to the market and the market impact that innovation has in a regional economy.The typology is enhanced by the different threads of literature - innovation, technology, organization and marketing. The integrated approach allows academics and practitioners to understand how and where innovation occurs in firms and lays the foundation for robust metrics of the behavioral relationship between variables under study. The result is a set of assessment tools that permits diagnostics of the firm, industry, market and region. The second essay examines the relationship between innovation, emerging technologies, business firms\u27 investment structure, and specialized types of private equity used to finance emerging technologies. A conceptual framework is developed for financial investment and a set of hypotheses tested for investment between Ohio and U.S. firms. Ohio firms take a different investing approach than U.S. firms when investing in a firm\u27s stage of business development but are not significantly different when using specialized types of financing, investing in industry/technology niches, and investing in geographic markets.The third essay explores the role of innovation in business firms. The essay examines the reasons firms invest in innovation and then test the difference in the innovation behavior of firms. Descriptive analysis is per
