Strategic interactions in DRAM and RISC technology: A network approach

Interorganizational cooperation in some high-tech industries is no longer confined to two-company alliances, but entails industry-wide alliance networks. This article examines how industry analysis and network analysis can be combined to provide a thorough understanding of how network positions, and the overall network structure, may play a part in cooperative strategies. Industry analysis can indicate which properties of the network structure and network positions are congruent with the firms' cooperative strategies, but tells us little about how these network characteristics can be measured. Network analysis provides such measures, which can then be used as feedback in the industry analysis. The article illustrates this approach by comparing the alliance networks associated with the DRAM and RISC microprocessor technologies.     

Interorganisational project dynamics: A longitudinal study of perceptual distance and client-contractor collaborative relationships

Despite the importance of good collaborative relationships in interorganisational projects, clients and contractors often develop adversarial relationships due to perceptual distance about key project issues. In this case study research, we investigated how perceptual distance emerges and changes over time, and how the collaborative relationship between client and contractor develops alongside these dynamics. In this exploration, we built upon agency theory and stewardship theory as complementary perspectives for understanding client-contractor collaborative relationships. We gathered quantitative and qualitative data in two projects, conducting three assessments in about one year. We found that perceptual distance increased and decreased over time, and that a reduction was typically associated with the collaborative relationship being characterized by stewardship rather than agency. These findings suggest that a regular assessment and evaluation of partners’ perceptions of critical project issues is warranted to timely detect and counteract perceptual distance. Moreover, partners would best adopt a stewardship orientation to reduce perceptual distance, although this may take considerable effort given the distributive nature of many pre-project negotiations.

Diffusion of environmental business practices: A network approach

The purpose of this research is to build a conceptual foundation that examines network effects on the diffusion of environmental business practices (EBP) among suppliers. This research extends a network perspective to adoption of an environmental business practice across a large network of suppliers. The context of EBP is used to better understand adoption of a complex business practice, with perceived costs that are often greater than the perceived benefit. Variation in the level of structural and relationship embeddedness affect network diffusion of environmental business practices differently. Increased levels of structural and relational embeddedness are proposed to be positively associated with diffusion of EBP. From a practical standpoint, firms that leverage embeddedness may facilitate higher diffusion and adoption of environmental business practices. This facilitation may lead network actors to engage in EBP, and leverage benefits that may stem from these practices. This research introduces the concept of embeddedness to the environmental supply chain literature. Practicing managers can use the findings in this research to better position themselves within a network to diffuse EBP. This research also helps managers understand how supply chain members that are weakly connected to the primary network are important for introducing new ideas and innovations.

Knowledge transformation in project networks: A speech act level cross‐boundary analysis

Researchers stress the importance of understanding knowledge transformation in projects. To explore how knowledge is transformed across organizational and specialization boundaries in project networks, we observed 22 knowledge transformation cases in two project networks. We found that new knowledge was created across specialization boundaries and that knowledge was altered across organizational boundaries. When both organizational and specialization boundaries were crossed, new knowledge was created. From these findings, we developed a set of propositions and formulated these into a model of knowledge transformation in project networks. This research contributes to a better understanding of knowledge transformation processes and outcomes in project networks.     

Frontinus—A project manager from the Roman Empire era

We compare selected project management practices undertaken almost 2,000 years ago with current literature on best project management practice. We take a case study approach focusing on a person who could be seen to have taken a project manager, project sponsor, and champion role. We suggest that some project management approaches used in Roman times are routinely used today; however, changes in the culture and technology have transformed possibilities for project management techniques, and so changed approaches are inevitable. The paper provides useful insights about the nature of changes to project management practice that may be expected during this century.     

Justifying health IT investments: A process model of framing practices and reputational value

Despite important research contributions on the financial and operational dimensions of information technology (IT) value, justifying health IT (HIT) investments remains a difficult and enduring issue for IT managers. Recent work has expanded our understanding of HIT value, by focusing on the initial resource allocation stage, and through conceptualizations of value across multiple dimensions. Building on these developments, we adopt a performative perspective to examine the research question of how practitioners justify early stage HIT investments, with a focus on reputational value. We explored this question through a comparative field study of two hospital organizations in the English National Health Service (NHS). We found that practitioners' temporally orientated framing practices matter in justifying HIT investments, enacting different possibilities for reputational value. We develop a process model to explain these dynamics and highlight the mutability of reputational value, which can lead to different possibilities for restoring, enhancing, or maintaining reputation. We conclude by discussing the implications for justifying HIT investments.     

Structural investigation of supply networks: A social network analysis approach

A system of interconnected buyers and suppliers is better modeled as a network than as a linear chain. In this paper we demonstrate how to use social network analysis to investigate the structural characteristics of supply networks. Our theoretical framework relates key social network analysis metrics to supply network constructs. We apply this framework to the three automotive supply networks reported in Choi and Hong (2002). Each of the supply networks is analyzed in terms of both materials flow and contractual relationships. We compare the social network analysis results with the case-based interpretations in Choi and Hong (2002) and conclude that our framework can both supplement and complement case-based analysis of supply networks.

The “management‐per‐result” approach to international development project design

Results‐based management (RBM) has proved to be a valuable tool for international development project management; however, there are some inconsistencies that limit the use of RBM at the design phase to manage for results. This article presents a “management‐per‐result” approach to reinforcing the project design function of RBM and illustrates its application to a real‐life project. Shying away from a technocratic approach, it emphasizes a “quick‐and‐dirty” approach and proposes an updated version of the logical framework to include success criteria and factors and very rough estimates for both project costs and benefits for targeted project results for different types of projects (infrastructure development, “process” type of project, and so forth).     

Technology policy between ‘diversity’ and ‘one best practice’ — A comparison of Korean and German promotion schemes for new production technologies

Policy makers in all industrialized countries are increasingly orienting their science and technology policy towards foreign patterns. There seems to be ‘one best practice’ which is used by all nations to make their economies fit for global competition.This paper doubts this paradigm. By comparing the South Korean and German promotion schemes for new production technologies, it is shown that an appropriate technology policy has to take the individual national system of innovation into consideration. Merely initating the examples of countries with different frame conditions is inappropriate.Diversity in science and technology policy has been the precondition for the success of contributions of these policies to economic and technological development in both South Korea and Germany.

M-competition — A closer look at NAIVE2 and median APE : A note

Two observations regarding the M-Competition are presented. First, the seasonal indices that were used in the NAIVE2 method were not calculated using the exact procedures that were defined in the M-Competition paper. Second the median absolute percentage error comparative measure was not computed as one might expect it to have been and was not documented as such. The resolution of these matters might enhance the usefulness of the M-Competition study.
