Also from BPTrends, today's Email Advisor has an article on Alternative Process Analysis Models (direct link to PDF):

There are a number of process analysis models that are designed to focus on more complex human interactions. One example is the RAD approach of Oulds and Harrison-Broninski and another is the Closed-Loop Business Interaction Model of Winograd and Flores. Both are useful in special circumstances, but neither replaces a basic workflow diagram.

I definitely agree with their premise that a single, common notation should be used for describing business processes for both business and IT.
