The service level
The availability the item is being managed to.
The part
What it is
Different items warrant different levels. A component that stops production and a slow-moving accessory should not be held to the same standard.
Setting it explicitly is what turns safety stock from a habit into a decision with a visible cost.
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.
