First Business: Plan It Backwards, From Opening Day to Today
Plan your first business backwards. Write the finished state precisely: a number and a date. Then ask what must be true one month before it, three months before, six, nine. The chain of conditions ends at today and names the task for this week. Check every row against your money and your hours.

Only one business application in ten ever turns into a company that hires anyone.
It didn't have to be that way. Some of those nine might have hired their first person if the owner had steered with a control system instead of a hunch. With the Jirgenson Model, that number could look different. Not a promise. A different set of odds.
Now picture your own version. A notebook on the kitchen table. Page one says "Month 1: register the company". Page two says "Month 2: website". By page four the plan turns into fog, and the fog has a name: "then it grows".
Forward plans for a first business tend to end like this. Every step opens ten new options, and by month six you are guessing. The fix is to start at the other end.
The Jirgenson Model is scientifically proven to work (Zenodo record). It is new, so it could not help the businesses behind these numbers. Now it can help yours.
Starting a business forwards: why the fog wins
Half of all adults say the fear of failing would stop them from starting.
That fear is not a character flaw. It is what a mind does when it looks at a road with no end point. Many of those people might have started if they had seen the road drawn from the finish, step by step. Their odds could have looked different.
So stop planning from today. Plan from the end, the way a navigation app does. It knows where you are. It knows where you are going. Miss a turn, and it does not lecture you about the past. It takes the spot where you stand now and draws a fresh route from there.
Carry that into your start. At every step, ask one question: what must be true right before this? A chain of conditions appears. Its last link is today, and today gets a task.
How to avoid it: never write "Month 1" at the top of a plan. Write the finish line first.
The backward chain for your first business
This is the tool. It takes about 20 minutes and one sheet of paper.
Elena, a freelance designer from the model's examples, used it for her first product: an online book. Here is her chain, written from the end.
| When | What must be true |
|---|---|
| M14 | Income of €3,000 a month |
| M11 | Steady sales of 21 books a month |
| M9 | 1,400 page visits a month, converting at 1.5% |
| M6 | The first hundred newsletter subscribers |
| M4 | Launch |
| M3 | Manuscript ready |
| M1 | Outline drawn up, price set |
Look at the M9 row. 1,400 visits at 1.5% is 21 sales. That is the M11 row. Each link feeds the one above it, so a calculator can check the chain. And the first action falls out of the bottom row: the outline and the price, this week. Not "become an author".
Now build yours.
- Write the finish line precisely. One number, one unit, one date. "A business that pays me" is a wish. "Income of €3,000 a month by M14" is a finish line.
- Write today precisely. Savings, monthly costs, free hours a week, paying customers. No "roughly".
- Step back three months. What must be true at that point so the finish can happen? Write it as a number.
- Keep stepping back. Six months, nine, one. Each row answers the same question: what must be true right before the row above?
- Read the bottom row. That is this week's task. Put it in the calendar.
- Check the resources on every row. Money, hours, people. A chain that needs every evening and every weekend from someone with a full-time job is not a plan.
Here is the contrast, as an illustration. The forward plan says: register, build a website, find clients, grow. The backward chain says: paying clients before launch, so a price list before that, so the price list this week. The second one fits on a sticky note, and on Friday you can tell whether it worked.
Entrepreneur fear and a checkpoint you can see
More people are scared to start a business today than five years ago.
Fear grows in the dark. A plan with checkpoints switches on the light. Some of those frightened people might have started, and stayed open, if every month had told them in numbers whether they were on track.
The backward chain gives you that for free. Every row is a checkpoint with a date.
Alex is thirteen and wants a €300 bicycle by 1 September. He walks backwards: €235 on 1 August, €170 on 1 July, €105 on 1 June, €40 on 1 May, the day he drew the plan. On 1 June he has €90. The plan said €105. The gap of €15 jumps off the page at the first checkpoint, while there is still time to add a lever.
He does not count "in round terms". He goes from checkpoint to checkpoint.
How to avoid it: give each row of your chain a date in the calendar. On that date, hold the plan next to the bank statement. A gap you see in month two costs less than one you find in month ten.
What six more months of "someday" cost
Delay has a price, and the chain prints it in money.
Take Alex again. On 1 June he still needs €150 over three months: €50 a month. His two levers bring in €20 and €30. The chain closes exactly, with nothing to spare.
Now let him wait one month before he starts. He still has €90 on 1 July. The same €150 must now come in two months: €75 a month. His levers still bring €50. On 1 September he is €50 short, and the bicycle stays in the shop window.
A business feels the same squeeze in months of costs. Take Andrew, the coffee shop owner in the model's examples. At a 15% margin, his cash reserve at M8 sat 0.27 months above what his chain required. Change nothing, at 12%, and that room shrinks to 0.11. One breakdown would eat almost all of it.
Andrew once sketched a five-year goal of ten coffee shops. Walking back from M72 showed the main thing. If he does not free his hands today to write operating procedures, he has almost no chance of ten shops in five years. The mistake shows up today, not in year five.
The same arithmetic runs on your idea. Every month of "next spring" is a month the chain must make up later, with the same levers.
And while the idea waits, the job you wanted to leave keeps your best hours.
The business that never opens
The biggest failure isn't the business that closes. It's the one that never opens.
A start that never happens leaves no record. Some of those owners might be running a business today if their first step had been small enough to take on a Tuesday. The backward move makes it that small.
That is the real gift of the chain. It turns a distant goal into an assignment for the coming week. Elena's assignment was an outline and a price. Andrew's was a senior barista, so he could step away from the counter. Yours is the bottom row of your sheet.
How to avoid it: do not wait for courage or for a better year. Write the chain tonight and finish the bottom row before Sunday.
"I can't plan backwards, I don't know the numbers yet"
You know more than you think. You know your savings, your costs and your free hours. Those are the start.
For the rest, use five questions. Can the task be split into steps? Do you know how one step leads to the next? Is today described completely? Does the best next step depend on where you stand, not on how you got there? Do the steps add up to the whole? If you can answer the first three, the chain works as a technique.
It does not promise the goal is reachable. It shows what must be true. That honesty is the point: until you name the start, the end and the moves between them, the method produces nothing.
One more check. The goal must sit inside something that is growing. A perfect route to a shop on a dying street still ends in a dead end.
Where the backward chain stops
You now have the whole tool. It treats the symptom: you stop planning into fog.
The cause of most stalled first starts is still open. A chain built on a wrong starting number takes you, flawlessly, to the wrong place. And the chain shows a gap at a checkpoint without saying whether that gap is normal or an emergency.
Two steps close that gap.
- A measured starting point. One source for every number, so the chain starts where you are, not where you hope you are. Chapter 2.
- Zones. Lines set in advance between green, yellow and red for each checkpoint, so you know when a miss calls for action. Chapter 4.
The chain is one part of a loop that runs goal, state, gap, levers, plan, forecast. For a calm way to make the start decision itself, see fear of failure in business.
Key takeaways
- Plan a first business from the finish line, not from "Month 1".
- Ask one question at every row: what must be true right before this?
- Write every row as a number with a date, and check money and hours on each.
- The bottom row is this week's task. Finish it before Sunday.
- A month of delay is not free. The chain charges it to the months that remain.
Tonight, or next spring
You have two choices. Close this tab, put the notebook back, and keep a plan that turns to fog on page four. Or take one sheet, write the finish line at the top, and walk back to this week.
The chain gives you a route. A measured start and the zones keep you honest on it.

What is the first step in starting a business?
Write the finish line: one number and one date. Then work backwards, asking what must be true three, six and nine months before it. The bottom row of that chain is your first step. For Elena it was an outline and a price.
How far ahead should a first business plan go?
As far as the first result you can measure. Elena's chain ran 14 months. Then step back in rows of one to three months, so you can check each checkpoint against your bank statement.
How do you deal with fear of failure in business?
Give the fear a map. A backward chain shows what must be true at each checkpoint and what to do this week. Fear feeds on the unknown. A dated row with a number takes part of the unknown away.
This topic is covered in Chapter 15, The backward move: from the goal to today of Steer, Don't Guess: Setting Priorities, Reading the Numbers and Correcting Course in Business and Life. The numbers in the examples are illustrative; the book states its limits in Appendix G.
