Many businesses continue to struggle in today's economy, but business executive Eric Ries has a bold message for American entrepreneurs: "Go lean."

Ries is author of the book, "The Lean Startup: How Today's Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses."

He defines a startup as "an organization dedicated to creating something new under conditions of extreme uncertainty."

Ries feels these businesses are the "life blood of the American economy," yet many of them fail.
