The steps
How many actions it takes.
The part
What it is
From noticing the problem to speaking to someone who can help. Counted by doing it rather than by reading the design.
Menus, forms, verification and waiting all count, and each is a point at which someone gives up.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
