I've offered my views on the global leaders approach to "mastering technology" in four different ways;
Mastering Technology I-The 24/7 challenge-4/23 blog
Mastering Technology II- Email Management-4/24
Mastering Technology III-The Large Scale Audience=-4/26
I also need to point out the book you see to the right of this blog "Virtual Teams" written by Jessica Lipnack and the late Jeff Stamps. I had the great good fortune to work with Jessica and Jeff during my time in Shell. If you read the book you will see how their work influenced my own thinking about global teams and the leader's role in those teams. Jessica continues their work.
