The volume

How many leave at each stage.

The part

What it is

In absolute numbers and in value, since a stage losing few but large opportunities may matter more than one losing many small ones.

Measured over a period long enough that the numbers are stable rather than noisy.

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.
