The problem with most business plans I have read hundreds of business plans. Most of them are fiction. Not intentionally. The person who wrote it meant every word at the time. But three months later, the document sits untouched in a folder somewhere, completely disconnected from the decisions being made day to day. The standard advice tells you to write a business plan for investors, for the bank, for some hypothetical stakeholder who needs convincing. So people write something that sounds impressive rather than something that tells the truth. They polish the language. They inflate the projections. They create a document designed to persuade rather than to guide. Then they wonder why they never open it again. What a useful business plan actually does A business plan that works is not a sales pitch. It is a reference document you return to when you need to make a decision. Should I hire this person? Check the plan. Does this new opportunity fit what I said I was building? Check the plan. Am I on track for where I thought I would be by now? Check the plan. If your business plan cannot answer those questions, it is not doing its job. I worked with someone last year who had a 47 page business plan. Beautifully formatted. Complete with appendices. She had not looked at it in eight months. When I asked her what her target revenue was for the quarter, she could not remember. It was buried somewhere on page 23. We stripped it down to four pages. Revenue targets on page one. Key priorities visible immediately. She now checks it every Monday morning before planning her week. That is the difference between a document and a tool. Start with the decisions you will actually face Most business plan templates begin with vision statements and market analysis. That is backwards. Start by listing the decisions you will need to make in the next 12 months. Will you hire someone? Will you raise prices? Will you launch a new product? Will you take on a particular type of client? Your business plan should give you a framework for answering those questions. Everything else is decoration. For a client running a small consultancy, the decisions that mattered were: which projects to say yes to, when to bring in contractors, and how much to spend on marketing each month. We built her plan around those three things. Criteria for project selection. Contractor triggers based on pipeline value. A marketing budget tied to quarterly revenue. She uses it constantly. Not because it is comprehensive, but because it is specific to her actual choices. The sections that matter Forget the 30 section template. Here is what actually helps: What you are building and for whom. Two paragraphs maximum. If you cannot explain this briefly, you do not understand it well enough yet. How you make money. Revenue model, pricing, payment terms. Be specific. Not "we charge for our services" but "we charge £2,500 per project, invoiced 50% upfront, average three projects per month." What success looks like in 12 months. Three to five measurable outcomes. Revenue target. Client count. Profit margin. Whatever matters most to you. Write the number down. What you are betting on. Every business has assumptions. Yours might be that your target customers will pay a premium for quality. Or that you can acquire clients through referrals without paid advertising. Name your assumptions explicitly. When they turn out to be wrong, you will know what to revisit. What you will not do. This is the section most people skip. It is also the most useful. Write down the opportunities you will decline, the markets you will ignore, the services you will not offer. When someone approaches you with a tempting distraction, you will have already decided. The Business Plan Generator at alira.london walks through these sections specifically because they are the ones that translate into real decisions. Not because they impress anyone. Keep it short enough to re-read If your business plan is longer than you can read in 15 minutes, you will not read it. That is not a character flaw. It is human nature. I aim for four to six pages with most people I work with. Some need eight. Nobody needs forty. The length test is simple: could you re-read this document once a month without resenting the time? If not, cut it down until you can. Review it on a schedule A business plan is not a one-time exercise. It is a living document that should change as you learn. I recommend a monthly glance and a quarterly review. The monthly glance takes five minutes. Are you on track for your targets? Have any assumptions been proven wrong? The quarterly review takes an hour. Update the numbers. Revise the priorities. Adjust based on what you now know. John Lewis just announced £20 million going into their Glasgow store as part of an £800 million investment by 2029. That number did not appear by accident. Someone wrote a plan, reviewed it, and revised it as conditions changed. The scale is different, but the discipline is the same. What to do this week Find your current business plan and time yourself reading it. If it takes longer than 15 minutes, mark the sections you skimmed. Those are candidates for cutting or condensing. Write down the three biggest decisions you will face in the next six months. Then check whether your plan helps you make them. If it does not mention the relevant criteria, add them. Block 30 minutes on your calendar for the first Monday of next month. Label it "business plan review." When it arrives, open the document and check your progress against your targets. Do this for three months and it becomes a habit.
