Do not model the initial wiki structure on an existing process, whether it’s paper or electronic. Wikis function best when they grow organically in response to the culture of the group using them.
Implementing a wiki is a great time to ask the most often overlooked question when it comes to process – “Why?” as in “why do we do that?” If the answer is, “we’ve always done it that way,” then keep asking. It is likely that something implemented for a culture that existed in the past no longer applies to the current culture.
You will also need to do a periodic review to see if the content needs to be reorganized to accommodate changes in business goals, the team structure, or even the personality mix of the team members. Remember, a wiki will be a reflection of the community, and as the community evolves, so must the wiki.
Before you start, think about the way your team actually operates and interacts, rather than the way the company procedures say it should.
