Rapid Fire GBS -  CATCH THE BALL!

This session has been designed for audience participation and knowledge sharing with no excuses! Instead of slowly passing around a stick microphone, simply throw the soft ball to the first person in the room who’s meeting your eyes!

Delegates are encouraged to come along with ideas, comments and provocative questions for their peers. There won’t be such thing as hiding in corners!

Petter J. Karal, CEO, Seatower AS

Speed Networking

Realising the importance of connecting with your peers, we organised a moderated networking session where delegates are prompted to meet others in brief 3-minute rounds. The moderator will be keeping track of time and announcing participants when to switch partners.

Make sure you bring lots of business cards along with you!
