Business frequently talks about continuity plans and disaster recovery. And the two go hand-in-hand. But it's frequently TALK.

Continuity plans talk about business continuity (and that's frequently implemented) but not JOB continuity. What happens when a single person moves on? What do they do? What are their processes and contacts? Those are almost as critical in a business. The military covers it with Continuity folders - especially for one or two-deep positions (or you are SUPPOSED to have one). But it's seems to be lacking in the business world. Internal blogs and wikis server some of the same process, but it's almost as if their is information hoarding as opposed to information sharing.
