The connection between the design of a product, its essence, and its manufacturing
was illustrated for Jobs and Ive when they were traveling in France and went into a kitchen supply store.
Ive picked up a knife he admired, but then put it down in disappointment. Jobs did the same.
"We both noticed a tiny bit of glue between the handle and the blade," Ive recalled.
They talked about how the knife's good design had been ruined by the way it was manufactured.
"We don't like to think of our knives as being glued together," Ive said.
"Steve and I care about things like that,
which ruin the purity and detract from the essence of something like a utensil,
and we think alike about how products should be made to look pure and seamless."
At most other companies, engineering tends to drive design.
The engineers set forth their specifications and requirements,
and the designers then come up with cases and shells that will accommodate them.
For Jobs, the process tended to work the other way.
In the early days of Apple, Jobs had approved the design of the case of the original Macintosh,
and the engineers had to make their boards and components fit.
