The conditions

The circumstances under which the promise comes under pressure.

The part

What it is

Peak demand, thin staffing, supplier failure, a system outage, an unusual request. These are foreseeable and the promise was probably written without them in mind.

The conditions that matter are the ones that recur, not the ones that are dramatic.

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.
