The book Traction focus on the Entrepreneurial Operating System.

It takes about the accountability chart and the three major functions of your business.

At RFS, we call this the three-legged bar stool!

These major functions are  Sales and Marketing, Operations and Finance.

If any of these areas becomes weak, the restaurant as a whole will suffer.

But don't just take our word for it; read the book.
