Airlines are almost "lucky" in the sense that when they mess up training and processes, people die. As a result, they are somewhat motivated to fix it.
In other industries, we say "that didn't work, VCs, can I have another $2M" and are just told "yup, of course!" As a result, we learn slow.
Personally, I stole checklists from aviation and love it. I remember one week I was on vacation and we needed to do a complicated migration. I prepared a checklist for the migration, and someone other than me did it. There was no downtime. We used the same checklists for future migrations, and again, nothing forgotten, nothing missed. It may be obvious to say "landing checklist: gear down" but it's effective.
