The difference between a good and great product is the last 10%. Everyone has the same 90%…the same core features and similar pricing and a similar story. But that last 10% is the real differentiator. It is the part that separates you from your competitors. It’s the blood, sweat, and tears of detail. And it might take 50% of your time. But time is not what you’re measuring…you’re measuring the difference between good and great.
