When I was at the annual KM Asia conference in Singapore in November one of the speakers was Janan Goh who works for BASF in Kuala Lumpur. During his talk he spoke very briefly about something he called "Running Desk". My ears immediately pricked up as it sounded similar to a Randomised Coffee Trial and I asked Janan if he could send me more information. This he has very kindly done and has also taken the trouble to translate it from German into English. Thanks Janan.
The concept is a little bit more elaborate than an RCT but the essence is the same. It's about bringing people together across silos in an organization to get to know each other better.
In BASF's words: "It creates a better understanding between, scientists, engineers and business people"
Take a look here
I rather like the idea. In any large organization there are buildings that you never get to visit. In a "Running Desk" you get to meet people on their own turf. There is a lot of value in that.
And you don't have to run one exactly the same way as BASF. Take the RCT and Running Desk principles and design your own "silo buster".
