The cost
What holding the value actually cost.
The part
What it is
Revenue forgone, a person lost, a delay accepted. Quantified where possible, because the number is what makes the story credible rather than self-congratulatory.
Costs that turned out to be trivial should be recorded as such; overstating them is how values become mythology.
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.
Confidence
How firmly the cost is established, since these are frequently estimated afterwards.
