The deadline
When the decision has to be taken.
The part
What it is
Analysis arriving after the decision is a record. The deadline constrains the method more than the question does.
Where the deadline does not allow the ideal method, saying so and using a weaker one is better than delivering the right analysis late.
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.
