The direct cost

Marketing and sales spend attributable to winning this segment.

The part

What it is

Media, content, events and tooling, allocated to the segment rather than averaged across all of them.

Allocation is imperfect and a rough segment-level figure beats a precise organisation-level one.

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.
