Key Ideas & Recurring Themes

What the object can do is not the clue that advertises the move.

Two gulfs

Execution: how do I act? Evaluation: did it work? Close both with mapping and feedback.

Knowledge in the world

Labels, layout, and constraints remember so the person does not have to.

Human error is design error

Slips cluster where the object hid the next step. Change the object.
