The ability to see problems in a field is a result of familiarity with it. Someone who does not know a field sees nothing in it, neither what works nor what fails. Familiarity has a price as well, because someone who knows a field very well stops looking at it, and misses things too.

The condition for seeing a problem

The source opens with a plain statement. A person with no familiarity with how a scene or an area ought to be cannot easily spot the problems in it.

The booklet reads this as follows: spotting problems is a result of familiarity. Without familiarity with a field, you see nothing in it, and that includes what is going well.

Suppose an owner brings in a consultant from another trade. She sees none of the technical problems, and she sees the management problems perfectly clearly, because management is where her familiarity lies.

Or take an installer who visits a colleague in the same trade. Within ten minutes he has seen three things the colleague had not noticed in two years.

The farmer at sea and the sailor on the farm

To make the point, the source sends a farmer to sea. The wind is mild, the rigging creaks, water slaps against the hull, and the farmer is “sure the ship is about to sink.” He has no familiarity with how a ship should sound or look. So he misses every real problem, and he may take things that are perfectly fine for faults.

Look at how the farmer goes wrong twice. He panics at things that are normal, and at the same moment he overlooks the real problems in front of him. Someone who does not know a field misses things and raises false alarms, and both mistakes come from the same place.

Then the source turns the picture around. A sailor on a farm would walk past rust in the wheat and a gate standing open, and he would see no problem on a farm the farmer knew was heading for bankruptcy.

Two capable people, each completely blind in the other's field. Paying more attention would not change that.

Suppose a studio owner brings in a bookkeeper. The bookkeeper sees no problem at all in the designs, and sees immediately that the pricing does not cover the hours.

Or a garage owner who asks his wife why customers are complaining. She points at the waiting room, which he has not seen for ten years.

Now the reverse: the same garage owner asks another mechanic. The mechanic points at the order of the tools, something his wife could never have seen.

The tourist and the resident

The source offers a second image, just as exact. When a scene is unfamiliar, a person has to look hard to become aware of things, and that is what tourists do. Yet, according to the source, the old resident sees far more than they do while “walking straight ahead down the road.”

Here is the tension of the whole chapter. The tourist looks hard but cannot tell what she is looking at. The resident knows the place and no longer looks. Both miss things, for opposite reasons.

Suppose an owner in the first year of his business. He notices every detail in the studio, and he has no idea which of them matter.

Now picture the same owner in the eighth year. He knows exactly what matters, and he does not see the broken door that everyone who walks in sees.

It is the same person and the same business, and in each period he misses different things. At the start he lacks familiarity. After eight years he lacks the fresh look.

Why this lands on you

A long-established owner usually stands where the resident stands. You know your business better than anyone, and for that very reason some of it looks ordinary to you and you have stopped seeing it. The booklet says it directly: when it comes to the problems in your own business, you are the person least able to see them.

So familiarity cuts both ways. It is the condition for seeing problems, because without it you do not know what matters. It also takes from you the fresh look at things that have long seemed obvious.

The booklet suggests a way to get both advantages. Your eye knows what matters, and an outside eye sees what you have grown used to. Give that outside eye one question to answer: what is missing here?

The booklet gives this chapter two short exercises, called swap and record. The practice section at the end also has one called the outside eye.

If something in your business is stuck and you cannot see why, you may be looking at it from the resident's seat, where you know everything and have stopped seeing. Someone who does not know your business as well as you do may see it before you.
