The application at my prior employer was the highest risk of failure I had seen in a commercial application.

Something like 80+% of the logic was in SQL stored procedures across different tenants. Nobody wanted to apply static analysis or test automation against it so everything came down to memorization of the code base and the resulting implementations to user interactions in the corresponding web based application.

My experience with commercial software versus open source software has repeatedly proven the complexity of business requirements is completely unrelated to the challenges of scaling and maintaining a software product. It always comes down an appreciation of automation, organizational skills, and writing. I often see people try to cheat this with tools and abstractions only to later drown in debt and blame everything else.
