“An hour lost at a bottleneck is an hour lost for the entire system."
A founder I know runs a workwear business in the Midlands. Two years ago she was stuck at £600k revenue. Couldn't break through.
So she did what most founders do when they're stuck. She added.
Two new product ranges. Amazon. A marketing agency. A website rebuild. A referral programme. None of it moved the number.
The actual problem was that her two best-selling SKUs were out of stock for nine days a month. Every other lever was downstream of that one bottleneck.
She fixed the supplier issue in eight weeks. Revenue grew 38% the next year. None of the other initiatives mattered.
The framework
At any moment, your business has one thing limiting growth. Not five. One.
Eli Goldratt called it the constraint. Everything else can be polished, A/B tested, and dressed up. None of it moves the number until the actual constraint is fixed.
The mistake almost every operator makes is spreading effort thinly across every weak spot at once. The operators who win pour everything into the single constraint until it stops being one.
The 3-step playbook
1. Find it. Walk your customer journey from first impression to repeat purchase. Mark the single point where momentum dies. Slow turnaround. Drop-off in checkout. Stuck inventory. Manual handover. The constraint is the place work and customers stack up.
2. Fix it. Throw your time, money and best people at that one point until it's no longer the bottleneck. This is uncomfortable because it means starving every other initiative. Do it anyway.
3. Find the next one. The moment you fix one constraint, another emerges. That's not failure. That's the system working as it should.
The kicker
Optimisation without diagnosis is busywork.
Most founders are working hard on the wrong thing because the constraint is rarely where it looks. Find it. Pour everything in. Move on.
That's it for this week.
If there's a constraint in your business you can't quite name, hit reply with one sentence and I'll send a thought back. Free, no catch. I just want to know what you're working on.
