The denominator

What the reading is measured against, and why that basis was chosen.

The part

What it is

Practical capacity means capacity after maintenance, changeover, and the variability the asset must absorb.

Stating the basis is what makes utilisation figures comparable between assets and between organisations.

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.

Practical capacity
The denominator, after realistic deductions.
Measure shared type
Basis
Why this capacity figure, which is what makes the reading defensible.
Reason shared type
Theoretical maximum
Held alongside, because the gap between the two is itself informative.
