# The one question that tests whether you found the cause [Home](https://theonlyaxelj.com/en) › [Study](https://theonlyaxelj.com/en/study) › [Articles](https://theonlyaxelj.com/en/study/articles) author: [Axel Jedlitschka](https://theonlyaxelj.com/en/about) published: 2026-10-13 updated: 2026-10-13 language: en reading time: 5 min topic: Personal source booklet: [Finding the Real Why](https://theonlyaxelj.com/en/shop/introduction/finding-the-why) A real cause opens a door to action. If your answer leads to nothing you can do tomorrow morning, it is not the cause. One question rules out most of the answers you give yourself when something in your business stops working: does this cause open the door to handling it? If it leads to no action, then according to the source it is a wrong cause, even when it sounds right. In this booklet, a **cause** is the thing that brings the numbers back once you correct it. The booklet calls it the Why. An **explanation** can be entirely true and still change nothing. The question separates the two, and it takes a second. ## The sentence the whole booklet leans on The booklet calls this the central sentence of the whole booklet: “A real Why opens the door to handling.” From it the source draws one instruction, and it is worded as an action. Whenever you write down a cause, put the same question to it. If the answer is no, the cause is a wrong one. Why does that matter so much? According to the source, correcting a wrong cause does not leave things where they were. The numbers fall further, and you spend a month, money and effort to land in a worse place than you started. It pays to catch the wrong cause before you act, and not after. Take two answers that business owners give themselves all the time. The owner of an auto repair shop says January is always slow. That is true, and there is nothing to fix about January. A boutique owner says a competitor opened on her street. That is true as well, and she cannot close it down. Both answers are correct, and neither one opens a door. Then the same boutique owner notices that her front window display has not been changed in eight months. It sounds smaller, and it was the only one of the three things she could change herself. The booklet also gives a quick version of the test. Take your answer and ask what you do now. If what comes up is that nothing can be done because that is how it is, you are holding an explanation, and the cause has not been found yet. ## Why the cause has to be written down Notice that the source speaks about a cause you write down. The question works on a written sentence. A general feeling about the business gives it nothing to work on. As long as the answer stays in your head, it sounds more reasonable than it is. Put it on paper in one line, read it back, and most answers fall apart on their own. Say an owner writes that his customers do not value quality. He reads the line and cannot think of one thing to do with it tomorrow morning. So he writes a different line: he has no way to show customers what they got. Within five minutes that sentence produces three actions. Or an owner writes that the market is saturated. The next line she manages to write after that sentence stays blank, because there is nothing in it she can move. ## The second test comes after the fix The door question works before you act. The source has a second test that works afterwards: you corrected the cause, and the numbers either recovered or they did not. If they did, that was it. This test has a follow-up that most people skip. According to the source, any other remedial order that was given on the basis of a wrong cause has to be cancelled quickly. That matters more than it seems. By the time you find the real cause, you are probably sitting on a pile of older fixes made against wrong causes: procedures, rules and restrictions. They are still running, so they are still doing damage. **Finding the cause includes cancelling what you did before.** Picture an owner who finds the real cause but forgets the rule he brought in six months earlier, that every quote goes through him. The rule stays in force and keeps slowing everything down. Or an owner with four procedures, every one written in response to a different incident. Three of those were fixes aimed at wrong causes, and nobody ever went back to cancel them. ## A key is judged by the door it opens The source sums up the distinction in one image. The cause, it says, is “a key that opens the door to effective improvement.” A key is judged by one thing only: did the door open? How nice it looks, how long you searched for it and how logical it is make no difference. The same test applies to your answer. Suppose an owner spends two weeks on a deep analysis and concludes that the business lacks focus. It is a fine piece of analysis, and the door stays shut. Then someone in the workshop tells him that he answers the phone during appointments. It is an ugly sentence, and the door opens at once. So the answer that works is usually smaller and more awkward to admit than the elegant one. According to the booklet, that is a good sign, and there is no reason to be put off by it. ## What the booklet has on this The chapter this article draws on includes two exercises: writing the cause down, and the door test. After them comes a self-check. From there the booklet moves on to two signs that give away a wrong cause before you have acted on it. The next answer you give yourself will probably sound reasonable. What decides whether it is the cause is what it opens for you tomorrow morning. - [Finding the Real Why](https://theonlyaxelj.com/en/shop/introduction/finding-the-why): A complete diagnostic method, and one test that disqualifies most of what you've been telling yourself until today. --- [עברית](https://theonlyaxelj.com/he/study/articles/does-the-cause-open-the-door) · [Español](https://theonlyaxelj.com/es/study/articles/does-the-cause-open-the-door)
