Baseline magazine has a l-o-n-g story titled, "The Promise and Peril of PLM: Boeing's Dream, Airbus' Nightmare".
They, like us, haven't been able to get much closer to finding out what caused the A380 design disaster, although there is a hint that another problem might have been tolerance data not migrating from CATIA V4 to V5.
The article, by Mel Duvall and Doug Bartholomew, provides some details on the use of CAD for Boeing's Dreamliner:
* data stored in a 16TB data warehouse.
* contractors update their data to/from the warehouse twice a week.
* all contractors have to use the same software (CATIA V5, etc).
* Boeing paid the contractors' cost in obtaining and supporting the software.
* all software is updated four times a year.
* a total of 150 software packages are being used for design and data handling.
