This is a great book if you are too busy managing a business to spend the next two years in school studying business to go to business school. If you want management expertise, insight, and vision you'd develop while earning an MBA - but without spending thousands of dollars, sitting in lecture halls, purchase this book and get a CD-ROM with 17 evaluation business programs. These are working programs that you can try and utilize the built in data or put in your own data to learn if you like the program and would want to purchase the full version. If you don't like one of the programs, buying this book will have saved you from $100-$1000!
