The service levels
The standards attached to ongoing obligations.
The part
What it is
A service level needs a measure, a target, a measurement period and a consequence. Missing any of the four makes it decorative.
Consequences that are trivial relative to the impact of failure are a way of pricing the failure rather than preventing it.
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.
