Where does scaling business operations break first?

Where does scaling business operations break first?
At three predictable inflection points: 10 to 15 people, 2 to 5 million in revenue, and the third product line. Each break has a specific operational fix. None of them respond to generic scaling advice. The companies that scale cleanly anticipate the next break and install the fix before it happens. The ones that wait pay a recovery cost that is roughly five times the prevention cost.
