business process and business rules

At the NY Brainstorm BPM Conference, we had an interesting panel on the relationship (current and changing) between "business process" and "business rules."  The answers were intriguing.  Before revealing the answers, it would be interesting to pose some of the questions to the bloggers to see if the panelists and bloggers agree.  So, here are three very important questions.

(1) How do you model or describe "business process" for your projects (e.g., activity diagram,  process chart or swimlane, use cases, other, all of these?)

(2) Do you anticipate adopting a business process modeling standard (e.g., BPMN)?

(3) How do you represent business rules in those business process modeling deliverables?
