*Measure What Matter* by John Doerr is a very amazing book to learn about OKR - an alternate to KPI methods, where i personally think are a more wonderful approach to create a more cohesive environment inside organizations. This slide include a small snippets of what exist in the book.
For every COO, CEO, or many other C-Level in small medium large business, or non-profit organizations, I recommend you to purchase this book through Amazon, or many other wonderful book purchasing platform existed.
