Information technology innovations: general diffusion patterns andits relationships to innovation characteristics

While many scholars of organizational innovations have examined characteristics of innovations such as relative advantage and complexity and how they facilitate the adoption of an innovation by organizations, others have used mathematical models to fit diffusion patterns. In this study, the authors attempt to integrate these two areas of inquiry and explore the possibilities to predict diffusion patterns based on characteristics of the innovation and the adopting entities. Based on a cross-sectional sample of 313 large American firms, 20 information technology (IT) innovations were examined and their diffusion patterns assessed with respect to models that espoused internal and external influence. The mixed influence model (Bass model) was chosen as a robust common representation for the set of diffusion patterns. However, the external influence as represented by the coefficient of innovation was found to be extremely small and the internal influence dominates for all innovations. The other two parameters of the model, the saturation level and the coefficient of imitation, which represents internal influence, were then used to perform a cluster analysis. Five clusters of technologies emerged, and the potential relationships between their innovation characteristics and diffusion patterns were explored. Rigorous examination of these potential relationships by future researchers may result in practical methods for predicting patterns of IT innovation diffusion based on innovation and technology characteristics

An exploratory investigation of the effects of supply chain complexity on delivery performance

As just-in-time delivery has become increasingly commonplace and customer demands continue to tighten, the importance of fast, reliable delivery cannot be overstated. This is particularly true for firms competing internationally, where the complexity of the supply chain must be managed within a global network. To explore the linkage between supply chain complexity and delivery, a two-dimensional framework is proposed that conceptualizes the degree of complexity embedded in a supply chain along two major dimensions: (1) form of technology and (2) nature of information processing. Technology is characterized using a conventional operations strategy framework of structural and infrastructural elements. In contrast, information processing captures both the level of complicatedness and of uncertainty that exists in the supply chain. Collectively, these two dimensions create a two-by-two framework that defines supply chain complexity and provides a strong theoretical basis for linking different aspects of complexity to delivery performance. An exploratory empirical investigation using an international database focused on immediate upstream and downstream echelons of a supply chain at the firm level. Results show strong support for the linkages between delivery performance and both complicatedness of the product/process and uncertainty of the management systems. In contrast, little evidence was found that greater product variety and more complicated supply networks adversely affected performance. Thus, management initiatives to improve delivery performance are best focused on improving informational flows within the supply chain and leveraging new process technologies that offer flexibility to respond to uncertainty.     

VLSI supply chain security risks and mitigation techniques: A survey

Hardware is the foundation of security and trust for any security system. However, recent study has revealed that hardware is subject to a number of security risks. Some of the most severe risks come from the VLSI supply chain. Such risks compromise the foundation of any existing security design. In this paper, we present a systematic survey on these security risks and their corresponding mitigation techniques.

The relationship between information technology use and buyer-supplier relationships: an exploratory analysis of the buying firm's perspective

No doubt exists that information technology is emerging as a key resource in the purchasing process. Concurrently, buyer-supplier relationships are changing. The purpose of this research is to determine if there is a relationship between the use of information technology and buyer-supplier relationships. A brief review of the literature on the use of information technology in purchasing is provided. Next, the nature of buyer-supplier relationships is discussed. Triangulation-involving field interviews followed by a mail survey-was used to collect data and attempt to answer the three research questions. The three questions were the following. (1) What is the relationship between the use of information technology and frequency of information shared between buyers and suppliers? (2) What is the relationship between the use of information technology and the richness of information shared between buyers and suppliers? (3) What is the relationship between the use of information technology and buyer-supplier trust? Information technology is defined in terms of automated purchasing systems, supplier links via electronic data interchange, information systems and computer-to-computer links with key suppliers. The research results suggest that three of the different types of information technology were significantly related to the frequency of information shared among buyers. Two of the different types of information technology were significantly related to the richness of information shared. However, only one of the types of information technology appears to be significantly related to trust among buyers and suppliers.     

The impacts of speed-to-market on new product success: the moderating effects of uncertainty

Time-based strategy is becoming an important weapon to achieve competitive advantage in the current environment of fast-changing technology and customer requirements. Speed-to-market has become the mantra of both researchers and practitioners in new product development (NPD), but there are limited and conflicting findings on the relationship between speed-to-market and product success. A more important question is whether faster is always better. In a study of 692 NPD projects, we examined the relationship between speed-to-market and new product success (NPS) under different conditions of uncertainty. Our results indicate that speed-to-market is generally positively associated with overall NPS, but market uncertainty moderates the direct effect. Speed-to-market is less important to NPS under conditions of low market uncertainty. Our results also suggest that technological uncertainty does not affect the speed-success relationship. The implication is that it is more important to execute a time-based strategy in an unfamiliar, emerging, or fast-changing market than in a familiar, existing, and stable market. The limitations and future research related to these results are discussed.     

Aligning supply chain management characteristics and interorganizational information system types: an exploratory study

Supply chain management (SCM) and interorganizational information systems (IOIS) have gained significant importance, aided by anecdotal success stories of firms obtaining competitive advantage using these systems. Historically, the two streams of research have developed relatively independently, with operations and logistics researchers studying supply chains and information systems/information technology researchers covering the IOIS domain. Here, we describe the enhancement of knowledge that can be obtained by juxtaposing these two areas. This research study proposes a framework, the "supply chain management-interorganizational information system (SCM-IOIS) matrix," to help understand the alignment of IOIS capabilities with the needs of supply chain members. The framework is validated using data from IndustryWeek's census of manufacturers. The findings from this exploratory study support our proposition that firms align the levels of IOIS with the sophistication and coordination of their SCM efforts.
