The horizon
How far ahead the forecast reaches, and how often it rolls.
The part
What it is
Twelve months, updated quarterly, is the common arrangement and works for most organisations.
The horizon should exceed the lead time of the decisions it informs, which is the actual criterion.
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.
