The Agile Consortium and Unicom are organizing the Scaling Agile for the Enterprise conference in Brussels:

At this second year of the Scaling Agile for the Enterprise conference we will bring together stalwart thought leaders on Agile Leadership like Jurgen Appelo, Christopher Avery, Jenni Jepsen, Dave Snowden , Dan North  and other  speakers to show how to change the company culture . You will discover what is needed to create an Agile environment and what type of leadership styles are best suited to make the Agile mind set thrive in your organisation.

I will be covering this conference for InfoQ.
