Companies with tradition and history often find themselves in a vicious circle with regard to their current applications: the software has grown over the decades and is often comprehensive in terms of functionality yet partly out-of-date when it comes to technology. Experienced developers and users retire, valuable expert knowledge becomes lost. Processes become less transparent and are less well documented. The ever necessary development and adjustment of systems therefore becomes increasingly complex and error-prone. In the short term, the company is at risk of technological standstill, and in the mid to long term of losing customers and markets.
