Take the guessing out of what to work on

Perhaps you find yourself, either now or at other times, needing to do one of the following:

• • Launch a product 
  • Figure out why people aren’t buying 
  • Figure out why people are buying, so you can find more of them
  • See if people will pay for the thing you’ve made 
  • Determine out which features to add next 
  • Figure out why people buy again.

If any of those apply to you, this book is for you.
