Knowing Who Makes Which Decisions
At the core of your governance plan is the need to decide who can make decisions within your SharePoint implementation. A myriad of configuration settings are available for manipulation at four basic levels: farm, Web application, site collection, and site. Generally speaking, SharePoint farm administrators will manage the options at the farm and Web application levels, whereas power users with advanced training will manage the options at the site collection level. Nearly everyone in your organization who is involved with content creation or management will manage configuration values at the site level.
Your governance plan needs to specify which people and positions will be able to make decisions and commit changes at each of these four levels. Planning this out before you deploy SharePoint Server 2010 is the optimal method of ensuring success for your SharePoint deployment.
