Twenty-five years later, I'm a business operations consultant still solving the same problems, just from the other side of the table.
I've worked at every level in these businesses, not as a consultant brought in to observe. I picked, packed and despatched on the warehouse floor, kept things running as the IT engineer, and ran the operation as the ops manager. I implemented the systems, worked with them every day, and fixed what needed fixing.
That's why I know what a system needs to do for the person using it, not just the person commissioning it.
