The indicator

The single measure that decides whether the goal was met.

The part

What it is

The test is whether it would settle an argument. If two reasonable people could still disagree after seeing it, it is not decisive.

External measures are stronger than internal ones, because they are harder to influence directly.

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.
