David Parmenter is truly a king of KPIs.  I have read both the 3rd and the 4th editions of this book. Firstly, this book clearly defines what a KPI is and the myths around KPIs. Different types of measures and how to report them are clearly explained. Also, the author introduces to a concept called Critical Success Factor (CSF) – what it is and why is it so important to organizations and why all KPIs should be derived from CSFs. Comparing to 4th edition (I call the 4th edition as KPI yellow bible), exercises are there on wording measures, a new chapter is introduced on measures characteristics and I feel overall it is more organized. I strongly recommend this book to anyone who is interested in setting up KPIs in their organization.
