The next constraint

Where the queue moves once this one is relieved.

The part

What it is

Relieving a constraint always creates another, and knowing where it will move prevents surprise and allows sequencing.

Where the next constraint is worse than the current one, relieving this one may not be the right move.

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.
