The last 10%

When you’re building a product, the last 10% is often the hardest part to justify. Everything is in place. The core features work. But there is still that quiet suspicion that the product lacks a final layer of magic.

So what do you do? Joshua Porter explains:

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.
