Defining the work · The scope · Element
The inclusions
What is being delivered.
The part
What it is
At a level of detail where two people would agree what it means. “Improved reporting” is not a scope item.
Grouped so that a reduction is possible: a scope that can only be delivered entirely cannot be reduced when it slips.
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.
