The chain
Your business holds what its weakest link holds. Strengthening any other link changes nothing.
Think of your business as a chain. Leads come in, someone talks to them, someone sells, someone delivers, someone gets paid. Every link depends on the one before it.
A chain holds exactly what its weakest link holds. Not the average of its links. Not the sum. The weakest one.
That has an uncomfortable consequence. If you strengthen any link that is not the weakest, the chain holds the same load as before. You worked, you spent, you improved something real, and the business produced the same amount. It felt like progress. It was not.
Most owners spend years doing this. They improve the thing they can see, the thing they are good at, or the thing a vendor is selling this month. The stays where it was, so stays where it was.
The reverse is also true. A small improvement to the weakest link lifts the whole chain. That is why one dollar or one hour spent on the constraint is worth more than the same dollar spent anywhere else.
So the first question is never "what could we improve?" There is always a long list. The first question is "which link is the weakest right now?" Everything in this method is built to answer that one question with evidence, and then to act on it before touching anything else.
