Top class resource for understanding OKRs in and out - complete with myriad first-hand case studies.

As the person that introduced Objectives and Key Results (OKRs) to Google post having learnt them from the father of OKR's, Andy Grove, John's wisdom in this space is legendary. I had consequently been meaning to read this book for many years. I have created OKRs but it is good to understand more about them and have a refresher on best practice. 

This was more of a memoir at times and a huge amount of the book was about how different companies (particularly Google which croppedup many tunes) are/were using OKRs, some of which seemed very repetitive without adding much in the way of additional insights.

Some good points included, but it could have been so much shorter.

The first third is far too long and arrogant. The rest is interesting enough, but it would merit some pruning to make it more operational.

John Doerr has had an extraordinary career, and this book pulled me in quickly with the stories in the beginning. But as he introduced character after character with effusive praise for what a visionary leader, one-in-a-million strategist, or incomparable genius each of them was, I started wondering... what do OKRs mean for the rest of us?

Then comes the story about Intel "turning on a dime" to put Operation Crush into action - Doerr notes that, to this day, he's never seen anything else like it. Okay, so if you saw OKRs drive something like this once in like 1979 and never again for the rest of your absolutely extraordinary career, is this really a useful example?

There are lots of big claims here about the power of OKRs, without a lot of clarity on how it works in practice - e.g. how OKRs make it so easy and intuitive to turn down work that doesn't align with your priorities. So if that work still needs to be done, where does it go? Having just read The No Club last year, I'm guessing this non-promotable work is offloaded onto women. Groundbreaking! I also skipped the masterclass in whatever from Zume Pizza - they literally went out of business.

It's rare that I read a book and get absolutely nothing from it, but here we are.
