The 5% Rule: why doing it all is keeping your business small
In every business, about 5% of what you do drives the growth. Here is the five-day exercise to find your 5%, and why shrinking it is how the business gets bigger.
I run an exercise with every new coaching client in their first session. I call it Delegate to Elevate. It’s usually the moment the penny drops.
Most of the owners I work with are wired the same way. They want to be involved in everything. They want it done right, and somewhere in their head is the belief that nobody can do it the way they can. I know that thinking because I lived it for years.
When I was building, I tried to be everything at once. Head of sales, the one keeping the books straight, the one chasing contractors, and the one delivering the work to the customer. All of that on top of running the day to day and calling myself the boss.
Here’s what that gets you. Monday goes on reconciling accounts. Tuesday goes on chasing suppliers. Wednesday goes on untangling the diary. By Thursday I’d realised I hadn’t had a single proper sales conversation in four days. I was busy and knackered, and the bank balance wasn’t moving.
That’s the trap, and it’s a quiet one, because being busy feels like progress.
The 5% that actually grows the business
In every business there’s roughly 5% of what you do that genuinely drives growth. The rest is necessary, but it doesn’t grow anything. And here’s the catch: the 5% almost never feels like the productive stuff. It’s the work that’s easy to put off because it isn’t screaming at you.
For most owners I coach, the 5% is some version of selling, building better offers, hiring good people, and getting more leads through the door. Everything else, the admin, the chasing suppliers, the constant “have you got a second” interruptions, is real work that needs doing. It just doesn’t need doing by you.
The hard truth is that the smaller you can make your 5%, the bigger the business tends to get. Owners who try to keep their hands on everything stay small, not because they aren’t capable, but because they’re capable of too much.
Track five days, then circle the 5%
This is what I take new clients through, and you can do it yourself this week.
For five working days, write down every single thing you do. Every meeting, every email, every task, every interruption. Don’t tidy it up or judge it as you go. Just capture it honestly, because the value is in seeing the real picture rather than the one you think is true.
At the end of the five days, go back through the list and circle only the things that actually drove revenue or growth. Be strict. If it kept the lights on but didn’t move you forward, it doesn’t get circled.
What’s circled is your 5%. Everything else is your delegation list.
Most people are surprised at how much of their week is taken up by work that has no business being on the owner’s plate. That surprise is useful. It’s the start of building a team and a set of systems around you so that, over time, the 5% is close to the only thing you touch.
Where to start
You don’t fix this overnight, and you don’t need to. The first move is just seeing it clearly. Run the five day exercise, find your 5%, and pick one thing off the delegation list to hand over this month. Then another the month after.
This is the Systems part of CoreOS, the operating system I run my own companies on and install with coaching clients: building the structure so the business runs without you having to touch everything. If you’re at that stage and want a hand with it, that’s what Momentum, my one-to-one coaching, is for.
Track your week first. Then we’ll talk about what to do with what you find.
