“The consumer is the most important part of the production line.”— W. Edwards Deming, Out of the Crisis
Deming kept telling executives that the assembly line did not end inside the factory. The line ended in someone’s hands. If you could not picture the person at the end of it — what they were doing, what they needed it to do for them — you were running blind.
Most strategy decks fail this test. They describe a market: small businesses, mid-market enterprises, consumers aged 25–54. A market is not a person. You cannot interview a market, you cannot watch a market struggle, you cannot ask a market why it chose your competitor. Naming one real human — even a composite of three real humans — forces the team to make decisions a market can’t.
For Deming, the customer wasn’t a marketing concept; it was an engineering input. Every part of the system pointed at them. If the team can’t agree on who that person is, every argument downstream — what to build, what to cut, who to hire — is really an argument about that.
Purpose tells you why. Customer tells you for whom. Without the second, the first floats: a purpose with no specific person to point at is just a slogan.
Every section that comes after — the job-to-be-done, the aim, the theories about what’s in the way — is grounded in the customer you name here. If you change customer later, you change everything downstream. That is fine. Just be honest with yourself when it happens.
