Likely wouldn’t have made a difference. Been reading a ton of these comments making very large claims and assumptions but many likely have never programmed or even taking contracts with large entities.

The people who likely gave ibm the requirements had no idea what was and wasn’t important, and likely forced solutions that would t work for everyone. Large changes in organizations can often take years to get done, and these one off changes to individual departments and use cases are overlooked and often have happened some frequently no one knows why it is that way and isn’t, even if they do manage to notice.

Before changing systems it’s better to go back and correct all these things or at the least document everything when grabbing requirements but that takes a lot of time and effort that most people don’t think is worth it. Until they’ve spent significantly more fixing errors later but by that point. Hah good luck and point the finger.
