More on Dave Snowden and Cynefin
Marc Ever's blog has a link to Ton Zijlstra's post Every Signal Starts Out As Noise with more information on Dave Snowden and Cynefin. It inludes this picture taken from a presentation by Dave Snowden (ppt) (copyright IBM UK Ltd. 2003) which describes a model of the four realms of knowledge and the way in which we analyse and interpret Cause & Effect in each of them.
