End-to-end Knowledge Management
If you take a closer look (click on the image to see a larger version), you'll see some very practical examples of work processes that occur in law firms each day. When the experts start talking about codified knowledge, this is what I envision... The other part I like here is the 'loop back'. When KM is working well, a firm will have some excellent routines (and capturing technology) in place to gather the various 'outputs' in the diagram above. No 'loop back' equals no KM.
I'm usually not a big fan of diagrams or charts, but I think Tom's makes a lot of intuitive sense.
