The watcher
Who checks the indicators, and how often.
The part
What it is
Unassigned monitoring does not happen, and it does not happen quietly, which is why erosion is discovered late.
The watcher should be someone who would act on the reading rather than someone who would only report it.
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.
