It's nearly Halloween, and software is a magic most people believe in. Without understanding how it works. A while back, I wrote a post. Clients don't know what they want. A client saw it. I've been running an engagement for a while now. A very large, complex system wearing many hats. Four buttons replace 80%. Clients love to play product manager dress-up. Don't let them turn your business into a haunted house. Be the ghost in theirs.
