The mix · The split · Element

The proportion

What share goes to each.

The part

What it is

Stated deliberately rather than emerging from a series of individual channel decisions, which is how it is usually set.

The right proportion varies by category maturity, growth ambition and how long the sales cycle is.

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.
