There are several guides to OKR. But they lack the solid foundations that will allow you to start at the beginning and will enable to to successfully adopt OKR.

I wrote this guide for first-time OKR users, but in my experience many long-time OKR users also find it valuable. Many of them lack the proper concepts to win with OKR.

My advice is that you should read this guide cover-to-cover, as each section builds upon the previous ones. Reading it from start to finish will help you understand how the different OKR building blocks fit together and why OKR has been successfully adopted by great companies such as Google, Spotify, Twitter, Airbnb and LinkedIn.
