Despite growing emphasis on the importance of supply chain visibility, few companies to date have fully benefited from the information resources of their supply chain partners. A review of existing literature about supply chain visibility reveals that there are two essential forces at work, namely (1) collaborative behavior – i.e., firms willing to share information with supply chain partners in order to leverage social capital, and (2) opportunistic behavior – i.e., firms wanting to maintain some degree of information asymmetry in order to manage the behaviors of their supply chain partners. In order to identify the antecedents of IOS visibility, our operational definition of supply chain visibility, the two theories – resource dependence theory (RDT) and relational view (RV) – are used to cobble together a set of variables in a framework to investigate their relationships to IOS visibility. The data used in this study was collected from 124 intermediate component manufacturers in three different manufacturing industries. The results show that IOS visibility positively influences overall supply chain performance, as measured by operational performance. Regarding the antecedents of IOS visibility, factors including asset specificity, interorganizational trust, complementary resources, and joint governance structures are significant, whereas environmental uncertainty and interdependence are not significant. 相似文献

Digital libraries are evolving from content-centric systems to person-centric systems. Emergent digital services are interactive and multidimensional, associated systems multi-tiered and distributed. A holistic perspective is essential to their effective analysis and design, for beyond technical considerations, there are complex social, economic, organisational, and ergonomic requirements and relationships to consider. Such a perspective cannot be gained without direct user involvement, yet evidence suggests that development teams may be failing to effectively engage with users, relying on requirements derived from anecdotal evidence or prior experience. In such instances, there is a risk that services might be well designed, but functionally useless. This paper highlights the role of process modelling in gaining such perspective. Process modelling challenges, approaches, and success factors are considered, discussed with reference to a recent evaluation of usability and usefulness of a UK National Health Service (NHS) digital library. Reflecting on lessons learnt, recommendations are made regarding appropriate process modelling approach and application. 相似文献

Abstract Proponents of electronic mail systems (EMS) claim that they increase the productivity and efficiency of operations. Their use has mushroomed in the last five years in industrialized nations. The use of such systems in less developed countries is, however, practically nonexistent. This paper examines the barriers to their use in those countries. These barriers are divided into four categories: technical, economic, political, and social. Some strategies for dealing with those barriers are also presented. 相似文献

This study develops and tests a three-stage model that examines the role of the quality of shared information in interorganizational systems (IOS) use. The model provides a more inclusive method of measuring quality of shared information in IOS use through a re-examination of the impact of top management support and IT infrastructure capability, and by assessing the mediating effect of operational supply chain performance on the relationship between quality of shared information and overall firm performance. Our results suggest that the impact of the quality of shared information in IOS use on overall firm performance starts with top management support and IT infrastructure capability, and that these success factors positively impact the quality of shared information in IOS use. Moreover, our results indicate that the quality of shared information positively impacts operational supply chain performance, which, in turn, leads to improvements in overall firm performance. Overall, our results highlight the importance of high quality of shared information in IOS use. 相似文献

This paper evaluates the use of sales information systems (SIS) in the UK financial services sector. The study is based on a quantitative survey of a sample of sales and marketing managers in banks, building societies and insurance companies. Seventy-two usable responses were received and our analysis reveals that the systems that have been adopted are being used to provide information for little more than mailing lists. Further, the aspirations for our respondents for further data capture and analysis are low—such that their overarching goals of improving customer retention, customer relationships, and customer acquisition are unlikely to be achieved. This mismatch between our respondent's data capture and their strategic goals is associated with the further finding that our respondents place more importance on technical barriers to implementing SIS—such as fragmented market and sales information, high cost of development and poor data quality—as compared to the lowered importance placed on organizational barriers. Importantly, the latter barriers have been recognized in the literature as the true barriers to achieving the strategic potential of marketing information. We argue that the future promise of sophisticated use of the capabilities of current SIS is thus likely to be compromised, due to the lack of awareness, amongst our respondents, of the criticality of organizational and strategic barriers. 相似文献

E-business is of increasing significance in promoting agricultural economic development and restructuring and upgrading, yet agricultural firms’ transformation toward e-business in China is at a low level. To gain insights to why and how agricultural firms intend to accept or resist the revolutionary innovation of e-business, this study draws on the perspective of institutional theory and organizational innovativeness to develop an integrative model to fathom factors affecting transformation to e-business in agricultural firms in China. By analyzing the impacts of institutional pressures on perceived benefits, perceived barriers, and subsequent e-business transformation intention, the empirical results indicate that mimetic pressure, coercive pressure, and normative pressure have different levels of positive effects on perceived benefits; normative pressure has a significantly negative impact on perceived barriers, while mimetic pressure and coercive pressure have no significant effect on perceived barriers. Perceived benefits and organizational innovativeness have significantly positive impacts on e-business transformation intention, while perceived barriers have no significant effect. Perceived benefits play a partial mediating role between institutional pressures and e-business transformation intention. 相似文献

Inter-organizational Systems (IOS) are network-enabled information systems that extend boundaries of an organization. There is a growing interest among researchers and practitioners to understand how the use of IOS enhances firm performance. In this study, we examine how IOS use impacts an organization’s supply chain management (SCM) capabilities and supply chain performance. Drawing on the resource-based view theory, we examine two mechanisms that are essential for enhanced supply chain performance: (a) efficient IOS external utilization regarding its networked partners and (b) the maximization of IOS organizational management capabilities in supply chain management. Using data from 193 respondents from various manufacturers and distributors of fast-moving consumer goods, we confirm all the hypotheses posited in the research model. The results demonstrate the dual effect of IOS use in improving operational supply chain performance, SCM capabilities, and the mediating role of SCM capabilities. We discuss contributions of the study to research and practice. 相似文献

This paper presents a North-South technology gap model which combines the Schumpeterian approach to technical and structural change with the Keynesian perspective on effective demand and the Balance-of-Payments (BOP) constraint as drivers of growth. Three are the contributions of the paper. First, it develops a model in which the technology gap, relative productivity and relative wages co-evolve and may generate different paths of convergence or divergence between South and North depending on the parameters of the model. Second, the parameters of the model are associated with different types of policies, which allows for discussing how these policies may change the growth path. Finally, the model is used to discuss the contrasting experiences of Asia and Latin America since 1970. Convergence in Asia and divergence in Latin America have been extensively debated topics in the literature on comparative economic development, which highlights the crucial role of industrial policy. It is argued that the results of the technology gap model are consistent with the findings of this literature and helps understand the forces behind convergence and divergence. 相似文献
