At Google you can see the OKRs for any team, organization, and product area. You can see what our company strategy is and what we're doing?
With OKRs you can see if there is another team working on a similar project and say, hey maybe we should collaborate on that project. OKRs also brings ownership to who owns the success of a particular initiative. Now you can go to a team member and rely on them to deliver and say hey, I depend on you, you depend on me. Once again integrating your team and your company together rather than having silos.
