Executive’s Guide to Scrum
I enjoy everything Jeff Sutherland writes about Scrum.
I found this document (see below) on OpenView Partner’s website (Jeff Sutherland is affiliated, especially regarding Scrum).
In this case, I do not know for sure that he wrote this document (Executive’s Guide to Scrum), but I do know that, even if he did not write it all, it was strongly influenced by him.
So, go to this page: http://offers.openviewpartners.com/executive-scrum-guide
And download the 34 page guide. Good for Executives and managers. Really, good for all of us.
Note: You do have to sign in with an email address. I think Openview Partners is responsible for this.
