Escalation · The trigger · Element
The conditions
What causes escalation.
The part
What it is
Complexity beyond the first line, elapsed time, customer request, or severity. Each should be explicit.
A customer asking to escalate should always be sufficient, and frequently is not.
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.
