The purpose

Why the role exists and what would be missing without it.

The part

What it is

A role whose purpose can only be described as a list of tasks is usually several roles, or none.

This is also the honest test of whether to recruit at all — some purposes are better met by changing how work is organised.

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.

Role purpose
One sentence that a candidate could repeat back; if it takes a paragraph, the role is unclear.
Statement shared type
Linked capability
Ties the role to the gap it is closing, so it can be cancelled with the gap.
