Developing operational competence in purchasing

This paper contributes to the emerging theory of purchasing competence. First, it replicates and cross-validates the construct with five underlying supply-side competence dimensions of Narasimhan, Jayaram and Carter (2001), using telephone survey data from 200 high-turnover European companies. The addition of an IT Competence dimension to the construct is proposed and empirically validated. In response to the growing importance of services, equivalence of the competence construct across manufacturing and financial services contexts was shown using the structural equation technique of invariance analysis. Using set correlation analysis competence dimensions were found to be significant drivers of multiple operational performance measures. All competence dimensions had significant positive impact upon at least one performance measure. IT Competence had the most significant positive impact, driving Quality, Purchase-Order Cycle Time and Professionalism. Certain dimensions had significant negative effects upon performance, providing evidence for the possible existence of "competency trap" phenomena.Operational Competence; Purchasing; Empirical Methods;

Empirical Evidence of RFID Impacts on Supply Chain Performance

Purpose - The purpose of this paper is to investigate the actual benefits of radio frequency identification (RFID) on supply chain performance through the empirical evidence. Design/methodology/approach - The research reviews and classifies the existing quantitative empirical evidence of RFID on supply chain performance. The evidence is classified by process (operational or managerial) and for each process by effect (automational, informational, and transformational). Findings - The empirical evidence shows that the major effects from the implementation of RFID are automational effects on operational processes followed by informational effects on managerial processes. The RFID implementation has not reached transformational level on either operational or managerial processes. RFID has an automational effect on operational processes through inventory control and efficiency improvements. An informational effect for managerial processes is observed for improved decision quality, production control and the effectiveness of retail sales and promotions coordination. In addition, a three-stage model is proposed to explain the effects of RFID on the supply chain. Research limitations/implications - Limitations of this research include the use of secondary sources and the lack of consistency in performance measure definitions. Future research could focus on detailed case studies that investigate cross-functional applications across the organization and the supply chain. Practical implications - For managers, the empirical evidence presented can help them identify implementation areas where RFID can have the greatest impact. The data can be used to build the business case for RFID and therefore better estimate ROI and the payback period. Originality/value - This research fills a void in the literature by providing practitioners and researchers with a better understanding of the quantitative benefits of RFID in the supply chain

The impact of innovation and organizational factors on APS adoption: Evidence from the Dutch discrete parts industry

Advanced Planning and Scheduling (APS) systems have gained renewed interest from academics and practitioners. However, literature on APS adoption is scant. This study explores the impact of organizational and innovation related factors on the adoption of APS systems from a factors approach. The results from our field survey of 136 Dutch discrete manufacturing firms, show that management support, cost of purchase, number of end-products, and the value that firms attach to other users’ opinions are key-factors that directly influence the adoption of APS systems. In addition, professionalism, external communications, and innovation experience indirectly influence APS adoption.innovation;impact;advanced planning and scheduling (APS) systems;causal model;factors research;organizational context

Capacity dynamics of feed-forward, flow-matching networks exposed to random disruptions

While lean manufacturing has greatly improved the efficiency of production operations, it has left US enterprises in an increasingly risky environment. Causes of manufacturing disruptions continue to multiply, and today, seemingly minor disruptions can cause cascading sequences of capacity losses. Historically, enterprises have lacked viable tools for addressing operational volatility. As a result, each year US companies forfeit billions of dollars to unpredictable capacity disruptions and insurance premiums. In this dissertation we develop a number of stochastic models that capture the dynamics of capacity disruptions in complex multi-tier flow-matching feed-forward networks (FFN). In particular, we relax basic structural assumptions of FFN, introduce random propagation times, study the impact of inventory buffers on propagation times, and make initial efforts to model random network topology. These stochastic models are central to future methodologies supporting strategic risk management and enterprise network design

Sequential International Joint-Ventures and the Option to Choose

The purpose of this study is to formalize the optimal choice of market entry strategy for an individual multinational enterprise (MNE) from a dynamic perspective. It is argued that incorporating a suitable treatment of irreversibility, uncertainty and flexibility related to a MNEs investment decision gives further insights to the expansion, dissolvement, and optimal timing of international joint ventures (IJVs). The evolutionary process of the value of the foreign direct investment can be interpreted as a compound complex chooser option. The results suggest that uncertainty, size of equity share and future investment/divestment opportunities play an important role when it comes to transit from export to the first phase of the foreign direct investment commitment. The paper underscores the importance of modeling the dynamics of market entry and helps to refine the application of real options in the alliance context by providing a closed-form solution in continuous time to valueForeign direct investment, multinational enterprise, sequential investments, entry mode, international joint venture, real options

Business Challenges in Commercialization of Agricultural Technology

Technology has been a major driver of both the agricultural productivity increases of the past century and the financial success of many farm and agribusiness firms. The challenges of bringing new technology to market in the agricultural industry are changing - it is no longer adequate to conceive a new invention and convince farmers with a strong marketing campaign that they should adopt the technology that results from this invention. One of the plenary sessions at the 2003 IAMA meetings in Cancun focused on the challenges and opportunities in creating value from new technology. Participants included: Michael Boehlje, Center for Food and Agricultural Business, Purdue University; Lynn White, Vice President, Global Ag Services, Deere; Marcello Arguelles, CEO of Biosidus; and Greg Clarke, Technical Director, FXA Group. This synopsis attempts to capture the key observations of the session presenters and the discussion that followed.Research and Development/Tech Change/Emerging Technologies,

Transferring intermediate technologies to rural enterprises in developing economies: a conceptual framework

This paper integrates the contributions from different branches of the technology transfer literature to identify enablers driving the transfer of intermediate or appropriate technologies to recipients in rural areas of developing economies. An in-depth analysis of the literature shows that many enablers identified in the literature focus on high technology transfers and are of limited relevance in the context of rural enterprises. Other important enablers in this specific setting are ignored or insufficiently considered. This paper proposes a framework comprising a specific set of enablers that facilitates technology transfer in rural enterprises in developing regional economies

Globalization and Trust: Theory and Evidence from Cooperatives

We study the effect of globalization on the stock of trust in organizations. We present a simple model of endogenous trust and show that contrary to centralized hierarchies (pure limited liability firms), decentralized organizational structures (cooperatives) foster the emergence of trust. We treat organizations as directly observable ‘summary statistics’ for underlying trust and ask what will be the fate of trust as the world becomes increasingly globalized. Because the cooperative is an intrinsically less efficient organizational form and globalization implies harsher competitive pressures, conventional wisdom suggests that the viability of cooperatives is in jeopardy. We show that this is not necessarily true. If the increase in competition is bundled with an increase in uncertainty and risk, the cooperative may become a more efficient organizational form. We conclude that globalization does not necessarily erode trust. The case of Mondragón Corporación Cooperativa is used to motivate assumptions and illustrate the results.http://deepblue.lib.umich.edu/bitstream/2027.42/39978/3/wp592.pd
