The drift check

Whether the organisation is quietly closing its own trade-offs.

The part

What it is

Reviewed periodically as a strategic question rather than as a backlog item, because each individual closure is defensible in its own terms.

The number of exceptions granted is the honest measure of whether the position still holds.

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.

When the trade-offs were last reviewed as choices.
Date shared type
Still held
Intact, eroding or abandoned.

Pressure source
