--- title: "The Case Study Never Closes" description: "Business courses teach through case studies, and case studies almost always end in a decision to expand. I learned the other decision somewhere else." date: 2026-08-09 category: Business readingTime: "4 min read" --- I take Business Management at standard level for the IB, which means I have spent a fair amount of the last year inside Paul Hoang's textbook. It is a good book. It is organised, it is honest about what its tools can and cannot do, and it does not pretend that a matrix is a strategy. I recommend it without reservation to anyone doing the course. I also, before any of that, started things and ran them, and closed some of them down. Reading the syllabus after having done that is a strange experience, because the two do not disagree anywhere. They just do not overlap where I expected them to. ## Everything is taught through a growing company Look at how business is actually taught. You get a stimulus, a page or two describing a firm and its situation, and then you are asked what it should do. Ansoff to decide which market to enter. The Boston matrix to decide which product to feed. Break-even to decide whether the new line clears its fixed costs. SWOT to inventory the position before moving. Every one of those tools takes growth as the question and asks only about direction. Ansoff has four boxes and all four are ways of getting bigger. The Boston matrix has a dog in the corner, which is the closest the standard toolkit comes to admitting that a thing might simply need to stop, and even the dog is usually discussed as a candidate for repositioning rather than for burial. The implicit verb throughout is *expand*, and the only real variable is *where*. This is not a flaw in the course. It is a flaw in the case study as a format. A case study needs a decision with a defensible answer, and "keep going in some direction" always has one. It also needs an ending you can mark. Closure is a bad exam question because the honest answer usually depends on facts nobody put in the stimulus, and because the reasoning that gets you there is not the kind that fits in a mark scheme. So students learn twenty ways to answer "which way forward" and none to answer "is forward the question". ## What actually told me to stop Nothing on the syllabus told me to close what I closed. I want to be exact about this, because it would be easy to write the tidy version where a framework fires and the founder acts, and that is not what happened. What happened is that I noticed I had stopped wanting to open the thing. Not that it was failing. It was working, in the narrow sense that the numbers were pointed the right way and the work I did on it produced the effect it was supposed to produce. But every improvement I could see was an improvement to a machine I had lost interest in owning, and I was making them anyway, because the machine existed and improving it was the obvious next thing to do. That is the state nobody warns you about. Not the collapse. The competent, functioning, entirely defensible continuation of something that has quietly become the wrong thing to be spending your life on. A failing business closes itself. A working business will happily absorb every year you are willing to give it, and it will produce evidence the whole time that giving it another one was correct. The frameworks are no help here because they all take the goal as given. Ansoff assumes you want the market. Break-even assumes you want the volume. They are instruments for navigating, and the question I actually had was whether I wanted to be on the boat. ## The one that did transfer I do not want to leave the impression that the theory was decoration, because one piece of it turned out to be the most practically valuable thing I have been taught, and it is the thing every founder I have spoken to learned late and expensively. Profit is not cash flow. The textbook says this plainly, gives it a whole unit, and every student nods and moves on, because on paper it is arithmetic. In practice it is the difference between a business that survives a slow month and one that does not. Money you are owed is not money you have. Money you have collected but will have to hand over is not yours. A perfectly profitable operation dies in the gap between when it pays and when it gets paid, and it dies while the profit line is green. That one is worth the entire unit, and it is the piece I would go back and study harder if I could. ## What I would put in the syllabus If I could add one thing, it would not be a new tool. It would be a case study that ends in a shutdown, written so that the correct answer is to close, with the stimulus containing all the evidence that continuing is defensible. Let the students find every reason to keep going, because they are all there, and then mark the ones who close it anyway. That would teach the actual skill, which is not analysis. It is the willingness to reach a conclusion your own effort argues against. Everything in a business you built pushes the other way: the time already spent, the identity attached to it, the fact that stopping looks from the outside exactly like failing. Sunk cost is on the syllabus as a term. It is not on the syllabus as an experience, and the two are unrelated. I would rather be judged on the closures than the launches. Launching is enthusiasm, and enthusiasm is not scarce. Noticing early that a working thing is the wrong thing, and acting on it while it still looks like a mistake to everyone watching, is the harder skill and the rarer one, and I do not think any course can hand it to you. It arrives the first time you do it, and mostly what it leaves behind is the ability to recognise the feeling sooner the next time.
