Optimal Designs for Asymmetric Linear Paired Comparisons with a Profile Strength Constraint

Within the linear model framework the problem of determining optimal designs for paired comparisons of alternatives which are described by a set of discrete attributes is considered under the constraint that the alternatives in a pair are only allowed to differ with regard to a certain number of attributes. Whereas in previous treatments of this problem it was assumed that all attributes possess the same number of levels, here the general asymmetric case is discussed. We provide a characterization of optimal designs and demonstrate how this can be used to derive a solution of the design problem for many situations of interest.     

The “Oil Crisis” — a crisis for LDCs

It is the group of LDCs whose reserves of indigenous energy are so small that they desperately need sizeable imports of oil, but which do not have sufficient other resources to earn the necessary foreign currency for their oil imports, that is suffering most under the economic changes which came over the world economy as a sequel to the oil crisis. Its future destiny is now literally a difficult balancing on “a knife’s edge”.     

Corporate foresight and innovation management: A portfolio-approach in evaluating organizational development

The transition from a traditional industry-driven economy to a knowledge-based economy requires new concepts and methods for companies to sustain competitive advantage. Here, academia has identified corporate foresight and innovation as key success factors. While, content-wise, the contribution of futures research methods to the innovation process has already been researched, this study strives to explore the status quo of organizational development stages of both concepts. To do so, we developed a portfolio-approach, the so-called ‘Future-Fitness-Portfolio’, which enables companies to qualitatively compare amongst others and identify organizational improvement potential. In addition, we conducted expert interviews to explore future organizational development trends in corporate foresight and innovation management. As our research revealed, five strategic clusters can be identified within the portfolio. Consequently, we propose specific strategies for each individual cluster. We conclude that there will be two main organizational development trends for corporate foresight and innovation management in the future: in traditional industries with conventional business models and long product-life-cycles, companies will follow a different development path than companies in dynamic industries with innovative business models and short product-life-cycles.     

Separate or Integrate? Assessing the Impact of Separation Between Product and Service Business on Service Performance in Product Manufacturing Firms

Purpose: Investigating how the separation of the product and service business mediates the effect of management's commitment to the service strategy on service performance in product manufacturing firms.

Methodology: The authors surveyed 216 European manufacturers in the high-value durable equipment industry moving into the service business. After assessing adequacy of measurement scales, the authors tested statistically for mediation. Their results hold when replicating the study using a structural equation modeling approach and while testing for common method biases.

Findings: The authors find evidence that the creation of a separate service organization, organized as a profit center, has a significant positive mediating effect between managerial commitment and the services' financial performance. Although separation also has a positive mediating effect between commitment and non-financial performance, organizing services as a profit center had a negative effect on the service's non-financial indicators.

Research Limitations: Research limitations include (a) a sample limited to German-speaking firms in the high-value durable equipment industry, (b) measurements based on self-reported managerial perceptions of service performance, and (c) conceptualization of service as a single strategic response.

Practical Implications: Although the complementarity between products and services is high in the market, the authors' research suggests few synergies to leverage their integration inside the organization. Accordingly, management should, at least in transition efforts similar to the ones included in this sample, look into creating a separate and distinct service organization.

Value/Contribution: This research was driven by practical concern on how to organize service operations in a manufacturing firm. Initial framing of the research through the creation of the construct of separation of product and service business was used.
