The target

The intended utilisation level per asset.

The part

What it is

Targets differ by asset. Something with highly variable demand needs more headroom than something with steady demand, and the difference should be deliberate.

A target above ninety per cent should be justified explicitly, because it is a decision to trade delay for asset efficiency.

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.
