I seldom review books as I find that other reviews are sufficient. Although that's true for this book , I feel compelled to add my voice to those who find this a great Sharepoint book.
Over the last 6 months or so I've spent some time using or learning SharePoint, as such I have an "okay" idea of what SharePoint is, and an understanding of general end user functionality as well as the business value it provides. However as a Business Analyst it was important for me to understand how Sharepoint components fit together. I've waded through the Microsoft sites, Sharepoint blogs, and two other books but just encountered a list of features and marketing mumbo jumbo. After reading this book, I was able to develop a mental model of Sharepoint 2010, and understand how the major Sharepoint components/concepts fit together to deliver value to users.
If you are a business analyst and want to gain command of sharepoint, I strongly recommend that you start with this book, and then I would strongly recommend Essential SharePoint 2010: Overview, Governance, and Planning (Addison-Wesley Microsoft Technology Series) Thank you Mr. Cawood.
