I like that it allows us to break down our team's individual responsibilities into well-defined "OKs" which are easily measurable, but also have enough room for personal expression/wiggle space while still providing accountability if needed (which we never need!).
There were some difficulties with getting everyone onboard initially; however once people realized its benefits there was no going back! It has made my work more organized than before - from creating new weekly reports all at one place instead having multiple spreadsheets or documents created manually each week by different members within an organization where information could be lost every time someone left their desk without updating them first etc..
