The sensitivity

How much the answer moves when each input changes.

The part

What it is

Usually one or two inputs dominate. Naming them is what allows the valuation to be argued about usefully rather than accepted or dismissed.

A valuation whose sensitivity has not been tested should be treated as a single scenario rather than as a figure.

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.
