The horizon

How far ahead the forecast reaches, set against how long capability takes to acquire.

What it is

The horizon is not a matter of preference. It is determined by acquisition lead time, and a shorter one means the decision is made by circumstance instead.

Different capabilities warrant different horizons. Specialist roles and regulated qualifications reach further out than generalist ones.

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.

Comparing this against the horizon shows whether the forecast is early enough to act on.
