"Also, it had to be sufficiently simple for the German team’s staff to use without SAP support"
I see a few weak spots in this story:
- If the product does not need SAP support, then it isn't SAP. Unless version upgrades are counting as support, this will go nowhere inside a business that is living off the yearly maintenance support fees. So likely this product is going to be spun off in a separate business.
- The much touted HANA scalability could not play a significant role here unless the Germans built a small data center inside their training facilities. Which they did not, we would be hearing about that from a proud HW provider otherwise. So HANA was used, but not for what it is supposed to be used.
