Think about that for a second. You can fire a salesperson for missing quota. You can bench a process for failing QA. You can shut down a supplier for poor fill rate. But AI agents? They just keep running. Keep consuming API credits. Keep generating outputs nobody checks. And somehow that's called "scaling." Here's what I've learned running physical operations: The most dangerous cost isn't the one that's big. It's the one that's invisible. A $300/month agent that books zero qualified meetings isn't a small cost. It's a process failure with a subscription model. You wouldn't keep a logistics vendor who delivered 2% of orders on time. Why are you keeping an agent nobody can measure? The accountability gap in AI isn't a tech problem. It's a management problem. And management problems have one fix: someone has to own the number. Who owns the number on your agents?
