The contradiction that makes sense Primark built its entire business on one promise: come to the store, pay almost nothing, leave with bags. No online orders. No delivery. The model worked because the margins were so thin that shipping would have killed them. This week they announced home deliveries. Four years after their first steps into online, they are doing the thing they said did not fit their model. And I think they are probably right to do it. I have watched people running their own thing tie themselves in knots over this exact question. You built something around a specific idea. Then the market shifts, or you learn something new, or an opportunity appears that breaks your original logic. Do you take it? Or does taking it mean you have lost the plot? Why most contradictions are just drift Most of the time, adding a channel that contradicts your model is a mistake. I have seen it enough to recognise the pattern. Someone starts a service business, delivers everything personally, builds a reputation on that personal touch. Then they get tired, or greedy, or both. They hire people who are cheaper and less good. They add a productised version that strips out the thing people actually paid for. Revenue goes up for eighteen months. Then it falls off a cliff because they hollowed out the thing that made them different. That is not adapting. That is dilution. The test is simple: does the new channel serve the same customer need in a different way, or does it serve a different need entirely? Primark's customers wanted affordable basics without fuss. The store delivered that. Home delivery can also deliver that, if the economics work. The need is the same. The channel is different. Contrast that with a premium consultancy that starts selling cheap templates to "reach more people". The template buyer has a different need. They want a shortcut, not expertise. You are not expanding your model. You are starting a second business that competes with your first. The three conditions I have worked through this decision with people in London and elsewhere, and I keep coming back to three conditions. All three need to be true, or the contradiction is probably just drift. First: the unit economics must work independently. The new channel cannot survive by borrowing margin from the old one. If Primark's delivery only works because their stores subsidise the logistics, they are not expanding. They are bleeding. Run the numbers on the new channel as if it were a standalone business. Does it stand up? Second: you must be able to deliver the same quality of outcome. Not the same experience, necessarily. A different channel will feel different. But the customer should get what they came for. If your whole thing is personal service and the new channel removes you from the equation, you are not meeting this condition. Third: your existing customers should not feel betrayed. This one is softer, but it matters. John Lewis just reported widening losses, £124 million, partly because shopper confidence is down. When your customers feel uncertain about the world, they want certainty from you. If you suddenly do something that contradicts what they thought you stood for, you add to their uncertainty. Timing matters. How to test before you commit I am not saying you should never do this. I am saying you should know what you are doing before you do it. Run a small version first. Not a "pilot" in the corporate sense, but a genuine test with real customers and real money. Primark spent four years figuring this out. You probably do not need four years, but you need more than a spreadsheet. Track the right metric. Not revenue from the new channel. Revenue is easy in the short term. Track whether your existing customers stick around, and whether the new channel customers have the same retention pattern as your old ones. If the new channel brings in people who buy once and vanish, you are not growing. You are churning. Talk to the people who already pay you. Not a survey. An actual conversation. Ask them how they would feel if you added this thing. Listen to the hesitation in their voice, not just their words. When the contradiction is the point Sometimes the original model was wrong. Or it was right for a market that no longer exists. I worked with someone last year who had built a consulting practice around in-person workshops. Two days, intensive, high-touch. Then the world changed and in-person became harder. She resisted going online for eighteen months because "that's not what we do". By the time she made the switch, she had lost 40% of her clients to competitors who moved faster. The contradiction she was avoiding turned out to be the adaptation she needed. The question is not "does this fit my model?" The question is "does my model still fit the market?" If the answer is no, the contradiction is not a betrayal. It is a correction. What to do this week Map your current model in one sentence. Write down what you sell, to whom, through which channel, and why that channel fits. If you cannot do it in one sentence, you do not have a model. You have a collection of activities. List the contradictions you have been avoiding. Every business owner I know has at least one channel or product they have thought about and rejected because it did not fit. Write them down. Then run each one through the three conditions above. Pick one and cost it properly. Not a fantasy projection. Actual numbers. What would it cost to deliver? What would you charge? What is the margin?
