John Gruber’s illuminating review of the C4 conference called out a great line by Wil Shipley:

“This is all your app is: a collection of tiny details.”

That’s the best descriptive I’ve heard of any product, project, person, or object. A collection of tiny details.

Details pile up. One influences another. One often makes another possible (or impossible).

If you stack up a bunch of great little details you have a great shot at a great product. If you stack up a bunch of poorly executed details you have a great shot at a mediocre or bad product.

Of course cohesion doesn’t happen for free. You can’t just pile up a bunch of details and expect a perfect whole any more than you can pile up a bunch of bricks and expect the Taj Mahal, but carefully considered details do set the tone for a great product.

Just be careful and don’t get bogged down on the details early on.
