Three Core Questions

Through this book, we’ll be able to answer these three core questions about a system and a metric:

Question 1: Are we achieving our target or goal?

  1. Are we doing so occasionally?
  2. Are we doing so consistently?

Question 2: Are we improving?

  1. Can we predict future performance?

Question 3: How do we improve?

  1. When do we react?
  2. When do we step back and improve the system?
  3. How can we prove we’ve improved

The aim of this book is not learning how to create charts for our metrics; it’s about improving performance through these methods and these questions.
