reminds me on the decision taken by EADS to use different CAD systems in France and Germany ... resulting later in huge loses because of the difficulties to assemble the different parts of the Airbus A380... (cables to short...) xD

Update: (Airbus) engineers in Germany and Spain stuck with an earlier version of Paris-based Dassault Systemes' CATIA design software, even though the French and British offices had upgraded to CATIA 5. That meant the German teams couldn't add their design changes for the electrical wiring back into the common three-dimensional digital mockup being produced in Toulouse. ..
