The changes

Each change to the process, with the problem it addresses.

The part

What it is

Traceability is the discipline: this change removes that queue, this one eliminates that handover, this one prevents that rework loop.

Changes with no traceable problem are the ones that get reversed within a year.

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.
