The hardest decision nobody teaches you Starting something is exciting. Ending it is not. But if you run your own thing long enough, you will face this question: should we shut down this part of the business? I have sat with people who kept a failing service line running for two years past the point it made sense. Not because they were stupid. Because they were emotionally attached. They built it. It used to work. Walking away felt like admitting failure. BP just put their North Sea oil and gas business up for sale. Sixty years of production in that region, and they are walking away. That is not a failure. That is a strategic exit. The new CEO is simplifying the company and cutting debt. Sometimes the smartest move is knowing what to stop. Sainsbury's is doing the same thing with Argos. Selling it for £120m so they can focus on their core food business. These are not panic decisions. They are calculated exits based on clear criteria. You can make the same kind of decision. You just need a framework that removes the emotion. What a Decision Matrix actually does A Decision Matrix forces you to score options against specific criteria. Instead of "I feel like this is not working", you get "this scores 12 out of 40 against our strategic priorities". The structure is simple. You list your options down the left side. You list your criteria across the top. You weight each criterion by importance. Then you score each option against each criterion. The maths does the work. The result tells you what to do. I use the Decision Matrix tool at alira.london with clients facing exactly this kind of choice. Last month, someone running a marketing agency was trying to decide whether to exit their SEO service line. They had been debating it for six months. We ran it through the matrix in 45 minutes and the answer was obvious: the unit was consuming 34% of their operational capacity but generating only 11% of profit margin. The numbers made the decision for them. The criteria that actually matter Most people use the wrong criteria. They score things like "how much I enjoy this" or "how long we have been doing it". Those are not strategic criteria. They are emotional anchors. Here are the criteria I use when helping someone decide whether to exit a business unit: Profit contribution: What percentage of total profit does this unit generate? Not revenue. Profit. Revenue without margin is just activity. Resource consumption: What percentage of your time, team capacity, and attention does this unit require? Compare this directly to profit contribution. Strategic alignment: Does this unit move you toward where you want the business to be in three years? Or does it pull you sideways? Market trajectory: Is demand for this growing, stable, or declining? Look at the actual numbers, not your hope. Competitive position: Are you genuinely good at this compared to alternatives? Or are you just adequate? Exit complexity: How hard would it be to stop? Consider contracts, staff, client relationships, and reputational impact. Weight these according to your situation. For most small businesses, profit contribution and resource consumption should carry the heaviest weight. If something eats your time but does not pay, the maths is straightforward. How to run the matrix Get specific. Vague scoring produces vague answers. Score each criterion from 1 to 5. Define what each number means before you start. A 5 on profit contribution might mean "generates over 30% of total profit". A 1 might mean "operates at a loss". Write these definitions down. Multiply each score by the weight. Sum the totals. Compare. If you are comparing multiple business units, run them all through the same matrix. The unit with the lowest total score is your exit candidate. Do not adjust the scores after you see the result. That defeats the purpose. The whole point is to override your emotional preferences with structured analysis. When the matrix says exit A low score does not mean you have to shut down tomorrow. It means you need to make a deliberate choice. You have three options: fix it, sell it, or close it. Fixing requires a clear hypothesis about what is broken and a time limit. Give yourself 90 days to improve the numbers. If the metrics do not move, proceed to exit. Selling is often better than closing. Sainsbury's is getting £120m for Argos. Even a small service line might have value to someone who wants the client relationships or the team expertise. Closing is the last resort but sometimes the right one. Wind down contracts properly. Communicate clearly with affected clients. Do it with dignity. The cost of not deciding Every month you keep a failing unit running, you pay twice. You pay the direct costs of operating it. And you pay the opportunity cost of not focusing that energy elsewhere. I worked with someone last year who finally exited a training service that had been limping along for 18 months. Within three months of shutting it down, their core consulting revenue increased by 22%. They had the same number of hours in the week. They just stopped splitting their attention. Indecision is expensive. A Decision Matrix gives you the clarity to act. What to do this week List your business units or service lines. Be honest about what counts as a distinct unit. If it has its own pricing, delivery process, or client type, it is a unit. Run one unit through a Decision Matrix. Start with the one you have been avoiding thinking about. Use the criteria I listed above. Score it properly. The Decision Matrix tool at alira.london will structure this for you if you want a template. Set a decision deadline. If the matrix score is below your threshold, commit to a decision within 14 days. Not "we will review it". An actual decision: fix, sell, or close.
