An initial classification of supply networks

The articulation of supply networks, as an extension of supply chains, seeks to accommodate and explain the commercial complexity associated with the creation and delivery of goods and services from the source of raw materials to their destination in end‐customer markets. In place of the simplistic, linear and unidirectional model sometimes presented for supply chains, the supply network concept describes lateral links, reverse loops, two‐way exchanges and so on, encompassing the upstream and downstream activity, with a focal firm as the point of reference. A review of classifications of supply networks reveals that none of the existing approaches appears adequate for managers facing the practical problems of creating and operating them on a day‐to‐day basis. This research identifies differing emphases that may be required for managing within supply networks, according to the nature of the products for which they are created. Taking an established categorisation of supply chains as its starting point, the research first develops the conceptual basis, using strategy literature, and then tests the resultant initial model in 16 case studies. Finally, a new categorisation for supply networks is presented, using the type of product as a differentiator.

Supply management: is it a discipline?

Purpose – To examine management literature for guidance on what constitutes a discipline. To examine supply management publications to determine whether the field constitutes a discipline or an emerging discipline. To contribute a structured evaluation to the body of supply management theory/discipline development knowledge. Design/methodology/approach – Literature review of what constitutes a discipline and an initial assessment of whether supply management is a discipline. Development of research questions used to design tests, using combinations of qualitative pattern matching, journal quality rankings, and social science citations index impact factor. Application of the tests, to evaluate field coherence, quality and the existence of a discipline-debate, to determine whether supply management is an emerging discipline. Findings – An initial literature review finds supply management not to be a discipline, as the field lacks quality of theoretical development and discussion, and coherence. Tests for increasing evidence of coherence, quality and impact yield positive results, indicating that supply management is progressing in its theoretical development. The test findings combined with the existence of the start of a discipline-debate indicate that supply management should be judged to be an emerging discipline. Originality/value – Drawing from the management literature, the paper provides a unique structured evaluation of the field of supply management, finding it not to be a discipline, but showing evidence of being an emerging discipline.

A strategic case for e-adoption in healthcare supply chains

A growing body of literature suggests that greater benefits of e-business will be obtained when e-business is integrated throughout a supply chain. However, organizations are still cautious in adopting e-business technologies. This paper examines whether a strategic case for e-commerce can be recognised and the factors that influence e-adoption, using e-business development models, a contingency approach and a stakeholder approach. The paper explores the link of e-commerce with strategy and the potential strategic benefits, risks and problems. This paper analysed e-adoption in four diverse healthcare supply chains in the context of the English National Health Service (NHS). The fieldwork showed there is of limited use of e- in supply chains; there are key problems associated with perceived benefits and costs by different actors both within organisations and within the chain. The paper proposes a framework to link the case for e-commerce with the achievement of strategic objectives across three inter-related domains-health, supply and business.

Networking activities in supply networks

The paper traces the origin of the concept of supply networks and focuses on nine different networking activities related to the process of establishing and operating supply networks. These activities are associated with the linking of activities, tying of resources and bonding of actors. Findings from two extensive case studies of supply networks are discussed, focusing on the process of networking in a series of relationships in a set of supply chains constituting each network. The findings reveal some important links between individual activities i.e. specific networking activities that appear to be mutually supportive. Furthermore, positive and negative connections between activities performed in different relationships within each supply network i.e. network effects, are identified.

Impact of e-business on perceived supply chain risks

Purpose – The purpose of this paper is to understand the risks managers and individual supply chains perceive from e-business. Design/methodology/approach – This research takes a long-term, staged view of the risks managers and individual supply chains perceive from e-business. By taking a two-stage approach, investigating four supply chains at a three year interval, the research considers perceived risks from e-business and the extent to which these risks obtained. Findings – E-business has the potential to deliver substantial benefits, but it also involves new and different risks. This research finds that small firms (SMEs) adopted a “watching brief” rather than implemented e-business. Between the two studies it emerges that e-business can support rather than detract from inter-organisational relationships. Global forces are in evidence in terms of low cost competition, but low cost competitors are not e-enabled. Research limitations/implications – Limitations, pragmatism and opportunism in the sampling is acknowledged. For example, the work and concepts that led to the expectation of e-business dominating and decimating industrial supply chains may have been based in chains more open to external forces than the ones examined here. Further research is required that identifies the minimum critical mass necessary to retain national manufacturing capacity at a chain or sector level, and empirical work is needed on the suggested link between supply chain stability and certainty of payment. The cases here are based on four UK supply chains, so various chain forms are likely to have been excluded. Originality/value – This research, by taking a staged approach and going back to the same chain and reviewing perceived risks, identifies how the build up of numerous – but small – events, for example factory closures, can aggregate over time to be just as significant as high profile, headline-worthy risks. Methods that produce a snapshot such as a one-off survey may be inadequate for fully exploring an area such as risk. Especially if the risks are hard to assess and are biased toward high profile events – catastrophic risks rather than accumulations of smaller, less noticeable risks.

An asymmetric learning in complex public-private projects

This paper investigates how symmetrical learning activity is, between the public client and the private contractor in the contracting and operation of complex, long-term infrastructure projects. Drawing on empirical material from two United Kingdom (UK) private finance initiative (PFI) cases, the paper analyses differences in the absorptive capacity and learning capability between parties. It suggests the private contractor appears to be better equipped to acquire, embed and renew their learning. These findings reflect less than 5 years of a 30-year contract, suggesting a skewed (imbalanced) relationship, where the contractor gains more learning capabilities than the client. The paper concludes with implications for management practice and suggestions for future research directions.
