This study looks at the perceived ability of components of IT infrastructure integration and supply chain process integration to predict specific radio frequency identification (RFID) system deployment outcomes—exploration, exploitation, operational efficiency, and market knowledge creation. Data for this pilot research study was collected using a survey questionnaire administered online to members of the Council of Supply Chain Management Professionals (CSCMP). It was hypothesized that data consistency and cross-functional application integration, both elements constituting IT infrastructure integration, and information flow integration, physical flow integration, and financial flow integration, all elements constituting supply chain process integration would be positively associated with and predict the four RFID system outcomes. Multiple regression results show partial support for all four proposed hypotheses. Cross-functional application integration and financial flow integration predicted exploration, while data consistency and physical flow integration predicted exploitation. Data consistency and cross-functional application integration, on the other hand, predicted both operational efficiency and market knowledge creation. Supply chain managers planning to deploy RFID systems are alerted to the criticality of these IT infrastructure issues as they brace for a likely widespread implementation of RFID in supply chains they participate in. 相似文献

This study investigates the impact of information technology (IT) on supply chain agility measured by the ability to sense and respond to market changes, and the impact supply chain agility has on firm performance. Data were collected from supply chain executives at 193 U.S. manufacturing firms. The results suggest that IT improves the supply chain's ability to sense market changes by improving the adequacy, accuracy, accessibility, and timeliness of the information flows among members of the supply chain. IT also increases the supply chain's ability to respond to market changes by reducing the cost, and improving the quality and timeliness of developing and executing coordinated plans to respond to market changes throughout the supply chain. Importantly, the results indicate that enhanced supply chain agility has positive impacts on the firm's sales, market share, profitability, speed to market, and customer satisfaction. 相似文献

基于和谐管理理论，对基于资源基础理论和动态能力理论的IT能力进行了重新构建，并进行了维度划分，阐述了其意义所在。基于和谐管理理论与和谐信息化体系理论，和谐信息化有了新内涵，提出了和谐信息化是企业信息化的绩效，也是企业信息化的一个发展方向。通过对华南地区281个中国企业样本的实证研究，验证了IT能力量表构建的信度和效度，实证结果表明，IT人物互动能力是实现企业和谐信息化的最重要因素，由此表明，企业更应注重IT人物互动能力的提升。案例研究也印证了此结论。在今后研究中，可以IT人物互动能力为和谐主题，分析其在企业信息化各阶段的具体表现，并制定科学的提升计划，以促使企业和谐信息化绩效的实现。 相似文献

The ability to internationalize has become a competitive necessity for many SMEs, enabling their survival and access to larger markets. From an IS research perspective, one important issue is the strategic role played by the firm's IT capabilities in responding to greater environmental uncertainty and correspondingly greater information requirements, and in enabling the firm's internationalization performance. Given that such a major aspect of the influence of IT on the performance of SMEs has so far been ignored, the following research question is posed: to what extent does the match between the IT capabilities and information requirements of SMEs contribute to their internationalization performance? Our research model and hypotheses are based on Tushman and Nadler's information processing model. In revisiting this model, the aim was to show its continued relevancy and extend its domain of applicability. In order to answer the research question, we conduct a survey-based empirical study of 174 Canadian SMEs that have internationalized their activities. Our results show that a better match between IT capabilities and information requirements does indeed exert a positive influence on internationalization performance. We also find that the SMEs’ IT capabilities are influenced externally by the environmental uncertainty and internally by their internationalization mode. 相似文献

供应链敏捷性的以往研究忽视了供应链企业间竞合关系的存在,且集体横向竞合对供应链敏捷性的影响及其作用机制仍不清晰。本文基于动态能力理论、社会网络理论以及组织学习理论,深入探讨了集体横向竞合对公司供应链敏捷性的影响机制。采用Bootstrap检验方法对216份专业市场中大型企业的问卷开展实证研究发现：集体横向竞合能直接或间接地对供应链敏捷性产生正向且显著的影响。集体横向竞合与供应链敏捷性之间存在三条中介路径,其中网络嵌入性中介路径对供应链敏捷性的影响最大,其次是组织学习能力中介路径,而网络嵌入性与组织学习能力的链式中介路径对供应链敏捷性的影响最小,且网络嵌入性是集体横向竞合与组织学习能力之间的唯一中介。 相似文献

Global outsourcing increases the complexity of managing IT projects. Gender adds another level of difficulty when managing IT projects. Understanding country and gender—level differences may improve chances for success. This paper provides opportunities to better understand underlying country and gender differences of Indian IT workers. We used Hofstede’s value surveys module to analyze gender differences and cultural preferences of 107 Indian IT workers. After correcting for problems with outliers, none of the mean differences between men and women were significant at the 95% level; at the 90% level, we found differences in uncertainty avoidance and long-term orientation only. Our results suggest that women and men working in the IT industry may have more similarities in terms of national culture than differences by gender. To overcome possible differences in uncertainty avoidance and long-term orientation, IT outsourcers to India should ensure adequate professional development opportunities, mentoring programs, and clearly explained career path opportunities. Further, a focus on policies and management strategies that capitalize on the national culture of India, including group work to take advantage of collectivist tendencies, and clearly defined hierarchical systems to take advantage of masculine orientation and high power distances, may allow foreign companies to attract and retain men and women, where in many cases, national culture trumps gender differences. Future research should collect more data from women and investigate the effect of regional differences on cultural perceptions. 相似文献

This paper investigates the supply chain (SC) management and innovation strategies with the purpose to identify: 1) which commercial contracts are suitable to coordinate SC innovation projects; 2) which motivations push SC members to adopt contracts to pursue innovation projects; and 3) how contractual clauses differ in different stages of the innovation process. A comparative case study among five High Tech (HT) companies in the Netherlands uncovers the motivations for adopting certain contracts over others. The findings illustrate that contracts discussed in the literature (sales-rebate, buy back, revenue sharing, etc.) successfully work for commercial agreements but not at all for coordinating joint innovation projects. Motivations for adopting these contracts do not limit to general company characteristics but also stretch from historical reasons to future strategies. The findings help HT companies to setting up the basis of a contract to coordinate joint innovation projects within SCs. 相似文献

The digitalization phenomenon is leveraging new relationship models through the entire supply chain network. In this outlook, blockchain is a cutting-edge technology that is already transforming and remodeling the relationships between all members of logistics and supply chain systems. Yet, while studies on blockchain have gained a relative pace over the recent years, the literature on this topic does not report sufficient research cases on blockchain adoption behavior at the individual level. The present study, therefore, aims to bridge this gap, notably by helping understand the individual blockchain adoption behavior in the logistics and supply chain field in India and the USA. Drawing on the emerging literature on blockchain, supply chain and network theory, as well as on technology acceptance models (TAMs), we have developed a model based on a slightly-altered version of the classical unified theory of acceptance and use of technology (UTAUT). The model being developed was then estimated using the Partial least squares structural equation modeling (PLS-SEM). As the model was eventually supported, the results obtained revealed the existence of distinct adoption behaviors between India-based and USA-based professionals. In parallel, the findings appear as a useful contribution to and a sign of progress for the literature on IT adoption, SCM, and blockchain. 相似文献
