Targets and thresholds · The target · Element
The basis
Where the number came from.
The part
What it is
Process capability, an external benchmark, or what the plan requires. Each produces a different kind of target and a different response when it is missed.
A target from capability is achievable by definition; one from the plan may not be, and that is worth knowing in advance.
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.
