AUP is an iterative-incremental process consisting of four sub-processes or workflows:
The last three workflows are self-explanatory and also appear in RUP.
Notice what is missing:
Analysis and Design
Instead, AUP combines these into an agile modeling workflow. Agile modeling produces minimalist throw-away models.
Also notice that a final state is missing. In agile development you're never through!
In addition, AUP defines the same three supporting workflows as RUP:
As in RUP, the AUP workflows go through four phases:
And during different iterations, each workflow will be in a different phase:
However, the AUP iterations are required to be short (about two weeks).
