Just recently we had a meeting with a client that demoed their current business workflow process. One of our client's very clever business users created a hacky but also amazing VBA solution for sending emails, assigning work, creating reports, etc. It works just the way they want it, and our team was there to replace it. Made me sad, because our solution will cost a fortune, won't do half of what this guy's solution does, involves a third party SASS solution with a very limited API, and so it will cut him out of his ability to customize it.
