It's always nice when two pieces of work converge.
I've had the pleasure of consulting to BAA's KM team at Heathrow over the past month, and in parallel, have been researching the knowledge transfer processes which surround the Olympic Games. Both of these are good stories.
I was impressed to see the video below, which was Vancouver's "knowledge gift" to Heathrow. Nicely produced, and well received.
