Learn to talk to your CFO in their language - SharePoint 2007 Project Costing, Feasability, Planning and Governance

My good friend "Mr Cleverworkarounds" (I call him that because of his awesome blog - http://www.cleverworkarounds.com) has completed a series of articles where he transforms analysis of technical considerations into a costing model that will make sense to a CFO (Chief Financial Officer).
What am I talking about?
How much will this SharePoint 2007 project cost?
How much will this SharePoint 2007 project make/save me in the future?
When implementing massive SharePoint 2007 Projects there is a great deal of risk involved. SharePoint is great software, but at the end of the day its all about money, what is more important is how much will it cost? and how much will it make/save me in the future, you may not care about this if you are a technical person, but I bet management and the people paying you to work with SharePoint do!

Here's a rundown and the links, keep an eye out for my name in the WCM Scenario :)
