A mindset for long-living software systems
Not far away from the Rhine river in Cologne, tourists find one of the most famous sights in Germany: the Cologne Cathedral. It was built in a period of 632 (!) years and completed in 1880. And from then on, the renovation work started. As of today, the cathedral has not seen a day without scaffolding for over 100 years. The Dombauhütte Köln, the institution responsible for the renovation, even has its own article in the German Wikipedia.
