The IBM PLM solution, with CATIA(R) V5 software from Dassault Systemes for collaborative product development, will enable CIMOS to standardize its product development platform. With a prestigious customer portfolio including Audi, BMW, Citroen, Ford, Peugeot and Toyota, CIMOS will benefit from improved collaborative product development leading to reduced product design time by 15 to 20 per cent. The solution will be deployed company-wide, including four research and development facilities in Slovenia, Croatia, Bosnia and Herzegovina. This implementation underscores CIMOS' recent decision to standardize with a PLM solution from one supplier exclusively. "We wanted to standardize on one system to simplify our environment and minimize our training, so that people would be up to speed as quickly as possible," said CIMOS IT Specialist Davorka Vilus Vicic. "We found CATIA V5 easy to use, offering transparency to V4 data and proposing new functionalities such as Digital Mock-up and Kinematics that are just what we need. We also found out that we could implement it across many locations simultaneously. Overall, we see great potential in many areas for this mixed CATIA V4 and V5 environment of over 70 seats. We expect our partners and suppliers to follow us by using it as well." "For more than 20 years, Dassault Systemes has provided the manufacturing industry with the world's most powerful engineering design and data management solutions," said Etienne Droit, executive vice president, Sales and Services, Dassault Systemes. "The decision by CIMOS to standardize its entire product development organization on our CATIA V5 solution is another endorsement of the strength of our products in the automotive sector." IBM Business Partner CadCam Design Centar will install the solution. ### About CIMOS CIMOS, the leader in the Slovenian Automotive Cluster, was founded in 1972 and is Slovenia's leading designer and manufacturer of automotive parts, such as auxiliary braking systems, pedal systems, gearshift mechanisms and engine parts.
