Since I learned Open Space Technology last week, I am trying to encourage my colleagues to use this as much as possible. Some new joiners have hard time understanding OST and some people get scared away by the word "Technology" in OST.
Here is an analogy(may be modified :-) ) to explain OST.
Imagine a multiplex theater running movies in parallel. These movies are based on a theme and these movies were chosen by the people who came to see the movies. You have a global ticket to watch any movie you like, any time you want . If you don't like anymovies, you can as well walk out.
