As reported by Dave Barkholz, Fiat is pushing Chrysler to switch from CATIA computer-aided design software to a product that Fiat uses from Siemens PLM.
Suppliers may have to switch software, too, but that's not the big issue.
The question is whether this signals a trend. Will Fiat's Marchionne want Chrysler to switch in other areas, say from a long-standing brake supplier to one that Fiat uses? Chrysler's existing suppliers have been sweating over that possibility for months. With the software news, they're now more nervous than ever.
