I enjoy reading a variety of business books including books on topics such as leadership, marketing, and successful business principles.  I recently read The Ultimate Challenge by Fred Riechheld.  The Ultimate Question is simply asking your customers – On a scale of 1 to 10 how likely are you to tell someone else about my product/service?  From this question successful companies such as Harley Davidson are able to…

• Distinguish good profits from bad
• Quantify the economic value generated by customer word of mouth
• Assign accountability for improving customer relations

The book gives a very simple explanation of how to determine your companies NPS – Net Promoter Score. 

This is a great book for anyone who wants to improve the performance of their company or business.
