One of the most powerful examples we had of the use of wikis at the BBC was when we used one to pull together a policy for BBC staff who had blogs.
Having identified staff bloggers using our social networking tool Connect Nick Reynolds, a colleague from Editorial Policy created a wiki page, wrote a “straw man” policy and e-mailed the URL of the page to the bloggers. They then piled in changing, editing, improving and discussing their changes until they eventually arrived at a position of consensus and the wiki page stopped changing. At this point the “document” was taken to the formal organisation where it was further discussed and developed. This process has just been completed and the policy made public.
The power of doing things this way is clear when those affected by policy are able to get directly, and very efficiently, involved in its creation and as such are much more likely to support and adhere to its guidelines.
