This aligns with my 10 year experience as a consultant working with C suite level executives as well. The people I have worked with are extremely smart and have incredible knowledge about their business. They can think through the happy path quite well. But when it comes to edge cases, error handling, and detailed logic they generally do not have the education/training to think about this properly. I've converted a few access databases in my day which were surprisingly sophisticated yet the lack of rigor was very transparent. There were good reasons they needed to transition to software written by a developer.
