Schema Change / Forest Change Control

Hello all…
I am trying to create a Schema Change Control Policy and a Forest Change Control Policy.
Microsoft reccommends creating these documents in order to maintain managability of the Forest and Schema. My boss has now asked me to create these documents. Simply put, I can easily put on paper the impacts of forest and/or schema changes. However, I am looking for a reference that will provide me some documented information, perhaps scenarios, on changes to the Schema and Forest … besides the obvious effects. If anyone can help me out, I would really appreciate it.

Thanks,
