Running it · The early warning · Element

The response

What happens when the warning fires.

The part

What it is

Reduce scope, extend, add capacity or accept. All four are available early and only the last is available late.

Naming the options in advance is what makes an early warning useful rather than merely alarming.

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.
