Gunther Verheyen closed the first edition of the Scrum Days Poland in Warsaw by presenting Scrum.org's vision on "Scaled Professional Scrum". Gunther focused much on how the Nexus implements Scrum for 3-9 Scrum Teams.
This is the full version of the presentation. Time was too short to go through it completely. Highest value was still delivered.
Gunther shepherds the Professional series at Scrum.org and is Ken Schwaber's partner for Europe.
