Sommario/riassunto |
|
The International Conference on Extrusion and Benchmark was held for the fourth time. Invited keynote speakers and contributors from academia and industry reported on the latest advances in extrusion technology and its simulation. The contributions covered a wide range of topics and are grouped into the categories of: benchmark, microstructure, seam welds & composite extrusion, material flow & constitutive equations, friction evaluation, dies & tools, and process control & optimization. However, many more topics such as new materials and new profiles have also been covered. The keynote address |

Sommario/riassunto |

Best practices for picking up the pieces when projects fail There are plenty of books available offering best practices that help you keep your projects on track, but offer guidance on what to do when the worst has already happened. Some studies show that more than half of all large-scale project fail either fail completely, or at least miss targeted budget and scheduling goals. These failures cost organizations time, money, and labor. Project Recovery offers wise guidance and real-world best practices for saving failed projects and recovering as much value as possible |
