Hope this email finds you well. Today, I want to introduce you to a great business resource, Flevy.com. Flevy is the leading source for business frameworks and training guides. Their guides are of the same caliber as those used and produced by top tier consulting firms, like McKinsey, Bain, Accenture, BCG, and Deloitte.
Also, if you are a heavy PowerPoint user, they have a free plugin for creating various business diagrams in a few clicks. You can see screenshots and download that here: http://flevy.com/powerpoint-plugin
