Software product lines are a promising approach to develop multiple products by providing reduction in rework and a systematic way to exploit the synergistic relationships between products. Many software product line efforts risk failure by ignoring non-reuse aspects of software product lines. One should also consider how to increase the perceived value of each product in the line compared to c...

The point of this note is to explain the ideas in the above research paper without using any mathematics or technical jargon (the original paper contains both). The intended reader is someone who is interested in economics and finance but who is not an academic researcher. I welcome your comments on the ideas below, whether you agree with them or not; and also on the write-up itself -for exampl...

Design errors leading to rework and/or design changes are considered to be the primary contributor to schedule delays and cost overruns in design and construction projects. While design errors are deemed prevalent, most design and construction firms do not measure the number of errors they create, thereby having limited knowledge regarding their mechanism to undermine project performance. To ad...

Variation is inevitable in any process, so it has to be dealt with effectively and economically. It has been the focal point of many researchers to control, predict or reduce the variation of a product to increase its competitiveness in the current global marketplace. Reducing variation can be achieved in assembly lines strategically and dynamically. It can be reduced strategically by developin...

Performance indicators are key feedback drivers of organisation dynamics. However, the extensive evaluation literature gives no scientific basis for the selection or testing of the opportunities of such indicators. This paper discusses the development of a “dynamic balanced scorecard” for a federal government department. The balanced scorecard suffers from the limitation of all performance indi...

We consider a multiple arithmetical sum involving the Möbius function which despite its elementary appearance is in fact of a highly intriguing nature. We establish an asymptotic formula for the quadruple case that raises the first genuinely non-trivial situation. This is a rework of an old unpublished note of ours. 2001 Mathematics Subject Classification: Primary 11A25; Secondary 11M06

Abstract We rework the Mori–Mukai classification of Fano 3-folds, by describing each 105 families via biregular models as zero loci general global sections homogeneous vector bundles over products Grassmannians.
