It's a short read, with some good points but having read the book and watched "The Executioners Tale" (https://vimeo.com/86392023) I'd pick the video next time!
Key takeaways
- OKRs are great for setting goals, BUT without a system to achieve them you are as likely to fail as with anything else.
 - A mission keeps you on the rails - the OKRs provide focus and milestones.
 - Set only one OKR for the company - it's about focus
 - Timescales should be about 3 months - too long and it's too far away to have impact, and too short and it's not bold enough
 - Objectives are inspirational not metrics
 - Repeat the message. The goal needs to be in front of everyones mind and tied to all activities. - "When you are tired of saying it, people are starting to hear it" (Jeff Weiner, CEO of LinkedIn")
 - Heuristic for KRs - one usage metric, a revenue metric and a satisfaction metric.
 - A good key result should be a bit scary - a 50/50 confidence you can make it is about right.
 - Use health metrics to identify areas to protect as you meet the goals (what can't you screw up?)
 - Use the four-square template (http://www.tightship.io/assets/weekly-meeting.jpg) to keep focus
 - Reinforce the message at the beginning and end of the week (Monday discuss/challenge, Friday demonstrate/celebrate)
