The recurrence

Whether each stream repeats, and how predictably.

The part

What it is

Recurring revenue is worth substantially more than the same amount arriving once, because it changes what the organisation can plan.

Predictability and recurrence are different: usage-based revenue recurs and varies, which is a distinct planning problem.

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.

Recurrence
One-off, repeating or usage-based — each has a different planning value.
Choice shared type
Cycle
How often it arrives, which sets the cash rhythm.
Period shared type
Variability
How much it moves between periods, which is what usage-based revenue costs in planning terms.
Percentage shared type
