As a business you need to decide what your core competency is and play to that. If you're a food distribution company do you really want to hire staff to "dig into open stacks" or do you want to just call the vendor and let them sort it out?

The job of enterprise IT isn't to be the best at anything, it's to be stable and predictable.
