The Ehrenberg-Bass Institute for Marketing Science makes a distinction most SME owners have never been taught: organic sales growth is always the sum of two separate things, category growth and share change. If your category is growing 12 percent a year and your business grew 10 percent, you did not grow your business. You lost ground to competitors while the tide carried you forward anyway. Most owners cannot tell you which of those two forces produced last year's growth number, because nobody ever taught them to separate the two.

The named enemy is the revenue chart that only ever goes up and to the right, celebrated in every board pack without ever being asked the harder question underneath it: would this business have grown even if we had done nothing at all, simply because the whole category was expanding? A rising tide lifts every boat in the harbour, including the ones nobody is actively steering.

This matters most in FMCG and other category-driven businesses, where a strong national trend, a health shift, a price movement across the whole aisle, can flatter every player in the category at once. The owner who mistakes that tide for their own strategy is the one least prepared for the day the tide goes back out and takes their flattering numbers with it.

The Share-of-Growth Audit separates real competitive performance from market luck in four steps.

1. Find your category's growth rate. Industry association data, IBISWorld reports or your own supplier's category sales figures will usually give you a reasonable estimate of how fast the whole category grew over the same period your business did.

2. Split your own growth number in two. Subtract the category growth rate from your total growth rate. What is left is your actual share change, positive or negative.

3. Face the honest answer. A business growing 10 percent inside a category growing 15 percent is losing share while feeling like a winner. A business growing 6 percent inside a category growing 2 percent is genuinely outperforming, even though the headline number looks smaller.

4. Set next year's target against share, not just revenue. A revenue target with no reference to category growth rewards a business for coasting on a rising market and punishes it for real outperformance in a flat one.

“I have grown my business 5x since working with Kevin. Everything Kevin told me to do was the complete opposite of what I had been doing. Working with Kevin has truly been a complete game changer.”

The execution gap is comfort. A rising revenue number feels good enough that almost nobody wants to interrogate where it actually came from, especially when the honest answer might be that a flattering headline number is hiding real, quiet share loss to a competitor moving faster. That conversation, taking a growth number apart to see what is really driving it, is uncomfortable to have with yourself. It is far easier with someone outside the business whose job is precisely to ask the question the board pack was never designed to answer.

Nine companies built and a career spent inside category-driven businesses teaches you to distrust a happy revenue chart on sight until you have checked what the category itself was doing underneath it.

If you have never separated your own growth from your category's growth, that number might be telling you a very different story than the one on your revenue chart.
