I’ve written three business plans in my career. Each one was 25-40 pages long. Each one took weeks to prepare. And each one was opened exactly twice: once to write it, and once when someone asked for it. They were expensive shelf decorations.
The problem with traditional business plans is that they try to predict an unpredictable future. By the time the ink is dry, the market has shifted, assumptions have changed, and the plan is already obsolete. Nobody refers to a 40-page document for weekly decisions. It’s too dense, too static, and too disconnected from the daily reality of running a business.
What I use instead is a one-page business plan. One sheet of paper (or one screen) that captures the essential strategic decisions guiding my business. I look at it every week during my CEO review. I update it every quarter. And it’s been more useful than all three of those 40-page plans combined.
The One-Page Format
My one-page plan has six sections. Each section answers one question:
Section 1: Who do we serve? A specific description of my ideal client. Not a demographic profile — a real description. “Manufacturing companies in the DACH region with 20-200 employees, growing, and struggling with operations that depend entirely on the founder.” This determines every marketing, sales, and product decision.
Section 2: What problem do we solve? The core problem, stated in the client’s language. “The business can’t grow because every decision runs through one person.” Not my language — their language. This is what I hear on sales calls and in initial conversations.
Section 3: How do we solve it? Our approach in one to two sentences. “We build operational systems that run without founder involvement, using a three-phase process: audit, design, and implementation.” This is our methodology, our differentiator, our reason to exist.
Section 4: What are our three annual goals? Three measurable objectives for the year. Currently: (1) Grow recurring revenue to 50% of total revenue, (2) Reduce owner dependency score below 30, (3) Publish two books. Each with a specific number and deadline.
Section 5: What are our three quarterly priorities? These change every 90 days based on my quarterly review. Currently: (1) Convert three project clients to retainers, (2) Document remaining five critical processes, (3) Launch the advisory community.
Section 6: What are the key numbers? The metrics that tell me if we’re on track. Monthly recurring revenue, pipeline value, owner dependency score, profit margin, and cash runway. These are the same numbers from my financial dashboard.
That’s it. Six sections. One page. Everything I need to make aligned decisions every day.
Why One Page Works
Constraint forces clarity. When you only have one page, every word must earn its place. You can’t hide behind jargon or hedge with paragraphs of qualifiers. You’re forced to state your strategy in clear, actionable terms.
It’s actually read. A one-page plan can be reviewed in two minutes. That means you actually look at it — weekly, not annually. And a plan you review weekly guides decisions in a way that a plan gathering dust never can.
It reveals inconsistencies. When your “who we serve” section says manufacturing companies but your quarterly priorities include a project for a software startup, the inconsistency is immediately visible. On a 40-page plan, contradictions hide in the volume.
It’s easily shared. You can show your one-page plan to a team member, an advisor, or even a potential partner in a five-minute conversation. They can understand your entire strategy and provide meaningful input. Try that with a 40-page document.
It adapts quickly. When the market shifts or your circumstances change, updating one page takes 30 minutes. Updating a 40-page plan takes days — which means it doesn’t happen, and the plan becomes fiction.
The same subtraction principle applies to planning as to everything else. Remove everything that doesn’t directly guide decisions. What remains is your actual strategy.
Building Your One-Page Plan (The 90-Minute Exercise)
You can build your first one-page plan in a single sitting. Here’s the process:
Minutes 1-15: Section 1 (Who). Describe your best client from the past year. Not your ideal imaginary client — your actual best client. What industry? What size? What stage? What challenges? Write their description as if introducing them to someone.
Minutes 15-30: Section 2 (Problem). What was the main problem that client was trying to solve? Use their words, not your marketing language. If you recorded your sales conversation, listen to how they described their pain.
Minutes 30-45: Section 3 (Solution). How did you solve it? Not the 30-step process — the core approach in two sentences. “We did X, which led to Y.” If you can’t explain your approach in two sentences, you haven’t clarified it enough yet.
Minutes 45-60: Section 4 (Annual goals). What are the three most important things to accomplish this year? Not ten things — three. Each should be measurable: a number, a date, or a clear yes/no milestone.
Minutes 60-75: Section 5 (Quarterly priorities). What are the three steps that move you toward your annual goals in the next 90 days? These should be specific and actionable — not “grow revenue” but “close three new retainer clients.”
Minutes 75-90: Section 6 (Key numbers). What five to seven numbers tell you if the business is healthy? Pull from your financial dashboard and add any operational metrics that matter.
Ninety minutes. One page. A strategy document you’ll actually use.
Using the Plan Weekly
The plan isn’t a creation exercise — it’s a management tool. Here’s how I use mine:
Weekly (during CEO review): Glance at sections 5 and 6. Am I making progress on my quarterly priorities? Are the key numbers on track? If not, what needs to change this week?
Monthly: Review sections 1-3. Is my ideal client still the same? Has the problem or solution evolved? Are my recent sales conversations aligning with or diverging from these descriptions?
Quarterly: Full update. New quarterly priorities based on the quarterly review. Updated key numbers. Review annual goals and assess progress.
Annually: Complete rewrite. Fresh perspective on who, problem, solution, and goals. The annual rewrite is where strategic shifts happen.
This rhythm ensures the plan stays current and decision-relevant. It’s a living document, not a historical one.
When to Abandon the Plan
A plan is a hypothesis about the future. Sometimes the hypothesis is wrong. Signs that your plan needs more than an update — it needs a rethink:
- Your actual best clients don’t match the “who” in your plan
- The problem you’re solving has fundamentally changed
- Your solution isn’t producing the results it used to
- Your annual goals feel irrelevant or impossible
- The market has shifted in ways your plan didn’t anticipate
When these signs appear, don’t patch the plan. Start the 90-minute exercise from scratch. A fresh plan built on current reality beats an updated plan built on outdated assumptions.
The path chooser questions can help when you’re facing a fundamental strategic rethink. Sometimes the plan changes because you change — and that’s perfectly legitimate.
Takeaways
-
A one-page plan beats a 40-page plan because you’ll actually read it, share it, and update it. Constraint forces clarity.
-
Six sections cover everything. Who you serve, what problem you solve, how you solve it, three annual goals, three quarterly priorities, and key numbers.
-
Build it in 90 minutes. One sitting, one page. Start with your actual best client, not your imaginary ideal client.
-
Use it weekly. Check quarterly priorities and key numbers during your CEO review. Update monthly, revise quarterly, rewrite annually.
-
Abandon and restart when the hypothesis is wrong. Don’t patch an outdated plan — build a fresh one based on current reality.
