Microsoft published a new series of training videos on Office.com to introduce Visio users to Business Process Modeling Notation (BPMN). "The BPMN, Subprocess, and Diagram Validation features are part of the Premium Edition of Visio 2010."
The course provides both an introduction to the BPMN notation and a tutorial on creating BPMN diagrams with Visio 2010 Premium. Along the way you can see some of the other new features of Visio 2010 including Swimlanes, AutoConnect, Subprocesses, and Diagram Validation.
The complete course takes less than 30 minutes to view.
The videos are packaged as a course named BPMN Diagramming Basics.
We have tried to embedd the videos, but they all need re-recording and uploading, so for the time being, the site is embedded below. You can navigate here or use the visit the soure page to view the videos.
