Wiki Best Practice
Dave Pollard talks about A recipe for Managing Risk and a company called ProCarta that justifies codification by focusing on high risk areas. What really caught my eye was this:

"The flexible nature of the software allows the ideas, suggestions, newly-discovered best practices and warnings to be written, wiki-style, into the recipe, providing additional guidance for other users."

What a great idea. Often best practice takes so long to agree on that its outdated by the time its circulated and hence becomes distrusted, or it dies because new insights require a whole new release cycle. This sounds like an excellent balance.
