Factors Affecting Small Business: Sort Each One Into Four Bins

Your November plan was written in June. It has no idea the heating is on.

The till dips. The energy bill climbs. A competitor drops a price. By Friday you are doubting a plan that may be working fine.

Your spreadsheet has forty columns for what you did and not one for what was done to you. So every push from outside gets booked as your own mistake.

Book every outside push as your own mistake and you'll doubt a plan that works. The Jirgenson Model fixes that with real numbers and a lever for each force. It is scientifically proven that the Jirgenson Model works (doi.org/10.5281/zenodo.23964934).

Factors affecting small business: the whole list

A factor is anything that acts on your path to a goal. It helps, it hinders, or it shoves you sideways. Where it comes from does not matter. What matters is that it acts on the path.

Sort the usual suspects into two groups.

The right-hand column is the one that gets left off. Picture someone who wants to earn €100,000 in three months with nothing but a computer. The market is not the main obstacle. Missing knowledge, missing capital and no time to learn pull in three directions at once.

Every factor has a direction and a strength. Some carry you. A list of business headwinds with no tailwinds on it is half a list.

The four-bin sort

Take one goal. Give it fifteen minutes. Each step sits beside a real entry from the coffee shop and its neighbours.

1. List five factors, two from yourself

Use both columns of the table above.

Andrew, for his coffee shop: rain, rising supplier prices, a university building going up nearby, a coffee machine breakdown, the coffee shop across the street.

2. Mark the direction

Along the path, against it, or sideways.

Andrew: the university building runs along his path. Rain, supplier prices and a breakdown run against it. The rival across the street he marks "watch": it will not sit still.

3. Put the serious ones in the goal's units

A worry in words cannot be compared with anything. A worry in euros, points of margin or knots can.

Andrew: suppose the supplier raises prices by 30%. Ingredients cost €9,000 a month, so the factor is €2,700 a month, or 9 points of margin. A yacht does the same sum at sea: the boat sails at 5 knots, the crosswind pushes it east at 0.9. The helmsman steers 350 degrees instead of zero, and the drift is cancelled before it starts.

4. Set it against your strongest allowed lever

Find the biggest move your own rules permit. Ask whether it covers the factor.

Andrew's rule: prices up no more than 5% in one step. An 8% supplier rise costs €720 a month, and 2.4% on prices wins it back. Covered. The 30% rise needs about 9% on prices only to save the profit. Not covered.

5. Drop each factor into a bin

Absorb is the busiest bin. Weather, season and general price rises cannot be argued with. Adjust planned expenses for the heating season and for inflation, instead of copying June's figures into November. Alex, thirteen, saving for a bicycle, absorbs a seasonal factor the same way. In July the neighbours go on holiday and his odd jobs dry up, so he keeps a spare lever ready: selling his scooter.

That is the business risks list in a form you can act on. It turns the factors affecting small business into decisions. Every line ends in a verb.

What unsorted factors affecting small business cost

Andrew's first rainy Wednesday shows the price. The room was almost empty and revenue fell. Without his list, he would have decided the plan had failed and changed his prices that week. The cause was the weather. He would have thrown out a plan that was already working.

Now the money. Andrew's shop turns over €30,000 a month. At a 9% margin it keeps €2,700. A 30% supplier rise costs €2,700 a month. Left unsorted, one factor eats the whole month's profit.

The reserve has the same thin skin. It stood at half a month of expenses. At a 9% margin, a breakdown costing a tenth of a month's expenses pushes the two-month goal back by about a month. At 15%, by about half.

And the human cost: the owner who spends the night blaming himself for the rain.

The enemy is the word "market". It explains every bad month and fixes none of them. Give each push its own name and its own line, and the fog becomes a list.

"My business is different." The bins are not. A coffee shop sorts rain and supplier prices. Elena, a freelance designer, sorts holiday weeks and platforms that change their rules. She adds rival authors who answer her price, and her own thin knowledge of selling online. A thirteen-year-old sorts the July holidays.

Where the four bins stop

The sort is complete for one goal. Use it this week. But be clear about what it fixes: it names what is pushing you, and stops you blaming yourself for the weather.

The cause of most bad calls is still there. You know the push. You do not yet know how far it has carried you off course, or at which point a push turns into an emergency. And the list sees a factor only once it has arrived.

This is one step of a closed loop: goal, state, error, levers, plan, forecast. Two further steps close the gap:

• The error and its three zones. How far the factors together have pulled each number away from its goal, and where normal, acceptable and emergency begin. Chapter 4 holds the thresholds.
• Recognising a factor before it strikes. Four techniques that turn a surprise into a forecast. Chapter 8 holds them.

The full factor sheet, with the yacht and the arrows, sits in external factors in business.

A factor you can name is a factor you can steer around.

Two choices before the next bad week

You have two choices this week. Keep booking every dip as your own failure, and change a working plan the next time it rains. Or sort five factors into four bins tonight.

Next Monday revenue dips, and you check one line on the sheet before you touch a single price.

The bins tell you what is pushing. The zones and early recognition tell you how far, and how soon.

Test the logic for free: Chapter 1, with the refusal test. Or get the full control system on Kindle, on Amazon. It comes as a Kindle book, with every factor worked out in euros.
