J and Graves (Jordan, W. C., S. C. Graves. 1995. Principles on the benefits of manufacturing process flexibility. Management Sci. 41(4) 577–594) initiated a stream of research on supply chain flexibility, which was furthered by Graves and Tomlin (Graves, S. C., B. T. Tomlin. 2003. Process flexibility in supply chains. Management Sci. 49(7) 907–919), that examined various structures for achievin...

We determined the kinematics at the jet of 0716+714 from a re-analysis of multi-frequency VLBI data (5, 8.4, 15, 22 GHz) obtained during the last 10 years combined with data from the literature. For this intra-day variable blazar, only a lower limit of its distance is known (z ≥ 0.3). We find that 0716+714 is a relatively fast superluminal source (with a Lorentz factor of γ > 15), revising earl...

This position paper reflects on the implications for variability management related practices in SPL development when adopting a compositional style of development. We observe that large scale software development is increasingly conducted in a decentralized fashion and on a global scale with little or no central coordination. However, much of the current SPL and variability practices seem to h...

In this study, we explore the effects of project leader status in new product development projects. We predict and find that that project leader status increases project performance up to a certain point after which it decreases performance. Further, status increases the variability of project performance, that is, it leads to more extreme performance in both directions.

Jordan and Graves (1995) initiated a stream of research on supply chain flexibility, which was furthered by Graves and Tomlin (2003), that examined various structures for achieving horizontal flexibility within a single level of a supply chain. In this note, we extend the theory of supply chain flexibility by considering placement of vertical flexibility across multiple stages in a supply chain...
