The trigger

What happens when a signpost fires.

The part

What it is

Deciding the response in advance is what converts an early warning into early action. Without it, the signal is noticed and discussed.

The response is usually a review rather than a change of course, which is the appropriate first step.

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.
