The Rubber Band.

Stretch a rubber band between two fingers and it pulls. The pull is not a fault in the band, it is the entire point of it. Take away the stretch and nothing has any reason to move. The Rubber Band applies that to a business: the distance between where you honestly are today and where you have said you are going is what generates movement, and closing that distance honestly is the only version that counts.

The uncomfortable part is that the tension always resolves — but in one of three directions, and only one of them is the outcome you want. Most owners spend their energy making the discomfort go away, succeed at it, and then cannot work out why the business stopped going anywhere.

What is the Rubber Band model?

It is usually taught as structural tension, and Robert Fritz set it out most clearly. One end of the band is your vision: a specific description of the business you have said you are building, with numbers and a date on it. The other end is current reality: what is actually true today, in numbers, with the commentary removed.

Both ends have to be held at the same time and both have to be honest. A vision with no reality attached is a daydream. A reality with no vision attached is just a job. Tension only exists when both are in your hands at once, which is why the model is far more demanding than a goal-setting exercise. Goal setting only asks you to write the top end.

The three ways the tension resolves

1. Reality rises to meet the vision

The business actually changes until it matches the description. A hire is made, a price moves, a process gets built, a customer concentration comes down. This is the one everybody assumes they are doing, and it is the least common of the three, because it is the only one that requires anything to happen.

2. The vision quietly drops

The goal comes down to meet where you already are. Nobody announces it. There is no meeting where the three-year target is formally abandoned. It simply stops being mentioned, and a year later the ambition is a good, solid version of last year, and everyone agrees that was always the sensible number. This is by far the most common outcome for business plans.

3. Reality bends instead

The gap gets closed by changing what you believe about today rather than what is true about today. Run-rates quoted from the best month. Turnover talked about instead of margin. Two good weeks treated as a trend. The tension disappears and the business does not move an inch.

Options two and three both feel like relief, and that is exactly what makes them dangerous. The discomfort goes, and so does the reason for anything to change.

Why it matters when you own the business

Because you are the only person who holds both ends. An employee is handed a target by somebody else; you write your own, and you are also the person who gets to quietly revise it. There is nobody above you to notice that the number you talk about in August is smaller than the one you wrote in January.

Owners lose the tension in three ordinary ways. Some let go of reality: the management accounts stop being opened, the complaint gets avoided, nobody checks what the last five jobs actually made. What is left is a vision floating on its own, which is comfortable and produces nothing. Others let go of the vision: every hour goes on today's fire, and the answer to where the business is going is a version of onwards. There is no upper peg, so nothing is being pulled anywhere.

The most common failure is holding both ends but never at the same time. The vision comes out once a year at a planning day. Reality is checked on the other 364. They never meet, so no tension is ever generated, and the planning day gets remembered as a nice couple of days out.

What sizing the gap actually looks like

Here is an illustration with round numbers — not a client, just arithmetic you can follow. A trades business turns over £600,000 and the owner says they want a £1.5m business inside three years. That is the top peg, and it is a reasonable one.

Now the bottom peg, written honestly: net margin is 6 per cent, so £36,000 of profit. The owner personally does around 90 per cent of the quoting. One customer is a third of turnover. There have been no management accounts since October.

Holding both at once is uncomfortable, and it should be, because the gap is not a marketing gap. Getting to £1.5m at a 12 per cent net margin means £180,000 of profit, roughly £900,000 of additional revenue, something like three more crews, somebody estimating who is not the owner, an extra chunk of management overhead to carry it, and enough working capital to fund wages and materials before customers pay. That converts into moves with dates on them. The tension did not reduce. The bottom peg moved, which is the only resolution worth having.

How much tension is useful?

Stretch a band too far and it snaps. A vision so distant that no first step is visible does not produce tension, it produces avoidance, and avoidance looks a great deal like being very busy with something else.

The test is simple: can you name what the next ninety days require, specifically? If yes, the tension is working. If the honest answer is that you would not know where to start, the band is too long and you need an interim peg — a twelve-month position that is a genuine stretch from today and genuinely on the route to the longer picture.

Worth separating two things that get confused. Tension is structural: a gap between two facts. Anxiety is emotional. You can hold a large gap perfectly calmly, and plenty of owners feel enormous anxiety about a business with no gap in it at all.

How to use it this week

Put both ends on one page

Vision in numbers with a date at the top. Current reality in numbers, as of today, at the bottom. One page, somewhere you will actually see it.

Make the bottom end brutal

Write five facts about the business you would rather not write down. If nothing on the list is uncomfortable, you have written the version you show other people.

Check which end moved in the last twelve months

If the answer is the vision, you have already had resolution two and probably did not notice it happening.

Set an interim peg at ninety days

One number, one date, one person who owns it. Close enough that the first step is obvious, far enough that it is not automatic.

Say both ends out loud to one person

Tension needs a witness. Something you have only ever thought can be quietly revised. Something you have said to someone who will ask you about it in three months cannot.

Diarise a monthly ten-minute re-read

Same page, both ends, one question: which one moved. That question, asked twelve times a year, is most of the model.

Questions to ask yourself

• Out of ten, how honestly is your current reality written down anywhere, in numbers, today?
• Over the last year, which end of your band moved — and who decided that?
• What goal have you stopped mentioning without ever formally abandoning it?
• If somebody read only your numbers, with none of your commentary, what business would they conclude you were building?
• Is the vision at the top of your page one you actually want, or one a business of your size is supposed to want?

Where this connects

This is foundation material in Personal Coaching, and it is the reason coaching involves being asked the same uncomfortable question every month rather than once a year. If you want the models either side of it, The 7 Habits covers the private work that has to be in place before a vision means anything, and Scarcity vs Abundance deals with the assumption sitting underneath what you allowed yourself to write at the top of the page.
