The trigger
The condition that starts the next capacity change.
The part
What it is
A utilisation level sustained over a number of periods works better than a judgement about whether things feel tight.
The trigger has to fire early enough for the lead time, which means it is set well below full utilisation.
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.
