The yield

What the reuse actually produced.

The part

What it is

Planned derivatives against made ones. The gap is usually large, and it is a capacity finding rather than a commitment failure.

Where yield is consistently low, the honest response is to plan fewer derivatives rather than to keep planning ones nobody makes.

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.
