This feature lets you add upto 10 filters for your OKRs based upon answerable people.
How it works:
Go to Add Filter option for your OKR and select answerable people from your team you want to filter, then name the filter and click save. You will now be able to see a seperate section in your OKRs with the filter name you chose and the chosen filter applied.
It serves the purpose of making the process of Team's work progress analysis really connvenient.
You can apply the filter for team members working on the same project and review the progress of the entire project with the filter feature.
