T2 - International Journal of Production Research AB - This study develops a framework for analysing time-based competition and examines four supply-chain management strategies in make-to-order markets which can lead to cycle-time reduction: cross-functional product design participation, ‘just-in-time’ purchasing systems with suppliers, improved supplier delivery and quality performance, and work-in-process lot size reduction. A structural model and relevant measures were developed to assess the impact of these strategies on time-based competition, and the model was tested using interview data with managers in 40 plants from nine industries. Both just-in-time purchasing and supplier performance were found to have a significant effect on leadtime competitiveness, while cross-functional design and lotsize reduction did not. Several explanations for the lack of significance of the latter two variables were suggested based on qualitative observations and post-hoc analysis. Although the analysis suggests that the greatest progress towards time-based competitiveness can be made in the area of procurement of materials, the study points to the importance of managing the entire supply chain to attain this strategic advantage.

AU - Pagell, M.D. T2 - International Journal of Production Economics AB - Flexibility is often lauded in management journals as a key to success in batch manufacturing industries. One means of achieving this form of competitive capability is through investment in a “Flexible Manufacturing System”, defined as “…an automated batch manufacturing system consisting of NC machines, linked by automated material handling devices, that perform the operations required to manufacture parts” [41, p. 274]. Despite the many advantages and the potentially large market for such systems, widespread adoption of FMSs by American manufacturers has not occurred, while other forms of automation such as programmable robots have been adopted at a much faster rate. This study explains patterns of FMS adoption using a technological diffusion model developed by Rogers and Shoemaker (1971). The framework suggests that the manufacturers of FMS have ignored several dimensions of new product management critical to the diffusion of innovations. These dimensions include relative advantage, compatibility, product complexity, trialability, and observability. Given the economic justification procedures commonly applied to FMSs, successful diffusion will require major infrastructural changes in adopting organizations. Several managerial guidelines are suggested which may help FMS suppliers to improve the rate of adoption.

Nevertheless, the construct has not been precisely defined and ad hoc measures have been the norm in the literature. This paper describes the development of measures which address multiple dimensions of the concept of innovation radicalness and treat it as a continuous variable. A rigorous process of item development, reliability analysis, and both exploratory and confirmatory factor analysis was used. The developed measures meet psychometric standards, demonstrate criterion-related validity, and capture four dimensions of radicalness: technological uncertainty, technical inexperience, business inexperience, and technology cost. Findings support the conceptualization of radicalness as a continuum with multiple dimensions, and suggest that those dimensions may be differentially related to project characteristics and outcomes. The utility of these measures and dimensions as diagnostic tools in project management is discussed. Radicalness as a multidimensional concept is also discussed as a valuable tool in project planning, project evaluation, and understanding the strategic implications of pursuing radical innovation.< > DA - 1995/8// PY - 1995/8// DO - 10.1109/17.403738 VL - 42 IS - 3 SP - 203-214 SN - 1558-0040 ER - TY - BOOK TI - Re-engineering for time-based competition: Benchmarks and best practices for production, R & D, and purchasing AU - Handfield, R.

ABSTRACT

Although molecular mechanisms associated with the generation of mutations are highly conserved across taxa, there is widespread variation in mutation rates between evolutionary lineages. When phylogenies are reconstructed based on nucleotide sequences, such variation is typically accounted for by the assumption of a relaxed molecular clock, which, however, is just a statistical distribution of mutation rates without any underlying biological mechanism. Here, we propose that variation in accumulated mutations may be partly explained by an elevated mutation rate during speciation. Using simulations, we show how shifting mutations from branches to speciation events impacts inference of branching times in phylogenetic reconstruction. Furthermore, the resulting nucleotide alignments are better described by a relaxed than by a strict molecular clock. Thus, elevated mutation rates during speciation potentially explain part of the variation in substitution rates that is observed across the tree of life.
