The release rule

What governs when new work enters the system.

The part

What it is

Pull rather than push: new work is released when the system has capacity rather than when it arrives.

The rule needs enforcing at a single point, or work enters through several doors and the limit becomes decorative.

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.
