Audi Electronic Fault Information System (ELFIS)

Products: Software engineering

The Company

Headquartered in Ingolstadt, Germany, Audi AG is a major manufacturer of luxury cars. It’s a 99%-owned subsidiary (as of 2004) of Volkswagen, the largest car manufacturer in Europe. Audi produces more than 960 000 cars per year with renowned models such as the A4, A6, and A8 in its lineup of A-series cars.

The Challenge

In 2005 Audi had seven autonomous IT systems for two plants with five production lines. These systems were used for electronics and mechanical fault documentation, cause analysis, and for reporting. None of the individual systems could cover all aspects of fault/cause data handling. Other challenges included missing interoperability and scalability, divergent user interfaces, and siloed databases.

The Solution

Between 2005 and 2009, EB developed a successful partnership with Audi production planning, line, and IT departments. EB implemented an all-in-one IT system with advanced functionality to succeed the existing systems. EB provided all of the application software, using up-to-date Java Spring web applications and Oracle database technology, and implemented an overall development lifecycle based on agile methods.

The Benefit

With the new system, Audi is able to address fault handling for electronic and mechanical parts in production in a single unified process for several German as well as international plants and production lines. A central component is the ability to jointly capture faults and their causes based on a single object naming terminology.
