The variance

Actual utilisation against target, and how long it has been diverging.

The part

What it is

Persistent divergence in either direction is the signal. Above target for several periods means capacity is short; below means the asset is a candidate for redeployment.

A single period’s variance is noise and should not prompt action.

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.
