This paper seeks to understand the significance of the various forms of logistical and technological differentiation as prerequisites for supply networking by introducing appropriate conceptual models and illustrative cases.

By studying the patterns of structural changes in 25 industrial companies, illustrated in four different positioning matrices, an empirical demonstration of the differentiation of logistical and technological capabilities is provided and compared with the trends observed in earlier studies of service industries and supply networks.

Considering the magnitude of changes of the logistical and technological capabilities observed in the case studies, differentiation has to be considered a precondition for – as well as a goal of – networking. More importantly, the conformance of the differentiation patterns of the capabilities and services that are embedded in the manufacturing supply chains with those of pioneering companies in service industries such as banking and retailing indicate that moves have been efficiency‐enhancing for both the individual companies and the portfolios of capabilities within the supply networks.

This paper proposes that companies in a supply network should focus first on developing a division of capabilities and finding the appropriate scale and scope of technological and organizational specialization through differentiation, and only then on building tighter inter‐firm collaboration by integrating operations and information systems. In that case integrative efforts in inter‐firm relations can produce chain‐wide benefits discussed at length in management literature.

This paper contributes to our knowledge on motivations of and obstacles for supply chain management by looking at the differentiation of capabilities relating to products and service strategies as well as technological and organizational specialization. In fact, the paper starts discussion at the junction where previous research has left off by concluding the need for focused provision of specific elements and mutually complementary competencies and capabilities.

The purpose of this study is to investigate how and for what purposes companies use interfirm information systems (IS) in supply chain management (SCM). Further, the drivers for the different uses of interfirm IS are investigated.

Two a priori constructs – the roles of interfirm IS in SCM and the drivers for interfirm IS use in SCM – are derived from the prior research. The case study approach is applied to analyze empirical data collected from 16 Finnish companies in order to assess the validity of the constructs.

The findings suggest that the proposed three categories – transaction processing, supply chain planning and collaboration, and order tracking and delivery coordination – represent well the different types of interfirm IS uses in SCM. Further, the findings suggest that the drivers behind these different categories of interfirm IS use differ.

The different purposes for which interfirm IS can be used in the management of supply chains are demonstrated. Further, the reasons for adopting interfirm IS for the different purposes are shown to vary and not to be as self‐evident as anticipated in the prior research.

The study addresses the lack of empirical research on how companies actually use IS in managing supply chain activities. It also contributes to the extant knowledge on the factors that drive companies to use IS in specific ways in their SCM efforts.

Asks what really has changed for and what to expect from future supply chains. Most surveys rank activities related to sourcing, operations, customer services and marketing in terms of their importance to, or degree of hindrance for, successful supply chain management (SCM). In this explorative study, analyzes the change of SCM both in terms of operational practices and organizational capabilities in some industrial companies. A focused survey traces the development of supply chains and networks over two decades. Observes the expected growth in use of supporting IT systems, extent of information sharing and scope of coordination efforts. Characterizes the different stages supply chain evolution on the basis of supply chain integration and changing roles and responsibilities of the companies. It seems that due to the continuous structural change of the business environment the very concept of supply chain, let alone the best practice of managing one, should be subject to re‐examination in a wider context. In order to reach the current ideal of SCM practices, the strategic preconditions for innovative networking also need to be in place.

The paper aims to examine the role of extranet portals – one‐to‐many web‐portals extending a company towards its suppliers or customers – in relation to system‐to‐system (S2S) links in facilitating information exchange between suppliers and buyers.

A case study approach is used to analyze empirical data collected from 16 Finnish companies concerning the use of inter‐organizational information systems in information exchange with supply chain partners.

For the use of extranet portals in relation to S2S links in information exchange between supplier and buyer, two concepts – partner‐extending role and information‐expanding role – emerged from the case studies.

The Finnish context and the research methodology chosen have to be taken into consideration when generalizing on the findings. As for future research, the findings indicate that, when studying the use of technological solutions for information exchange in supply chains, the interplay between the different types of solutions used should be acknowledged instead of studying the solutions separately.

S2S links and extranet portals can be used as complementary solutions in facilitating supply chain co‐operation and the related information exchange. Hence, practitioners should not only acknowledge the fundamental differences between these two types of information systems but also leverage these differences to achieve more synergy in the use of inter‐organizational information systems. Further, a conceptual tool is provided for assessing the use of extranet portals in relation to S2S links with supply chain partners.

The study contributes to the limited prior research on extranet portals and develops concepts that can be utilized both in future research and in practice.
