The cost

What the change cost in accumulated position.

The part

What it is

Years of repetition spent, campaigns reworked, and the period during which the market held the old position and encountered the new one.

Rarely calculated and worth an estimate, because it is the argument against the next unnecessary change.

The smallest level

The attributes it carries
