"Hercules is a very large system. Not so much in terms of users – the solution is only used by around 300 expert users plus a few analysts. However, with more than 425,000 lines of code, 468 user screens, 290 tables, integration with 17 other systems, use of 25 online web-services towards the product data system on orders for handling all the car configuration rules, as well as collecting information from other systems such as sales statistics, you could say that we're talking about the heart and the virtual soul of Volvo Cars. It was, therefore, very obvious that we had to plan the migration project very carefully to ensure we didn't accidentally cause any disruption to the system," Peter explains.
