On the productivity report you can review the productivity for a user, team or the whole company. You can filter for date and users/teams. It shows the project hours compared to the attendance time. You see how many hours are billable, non-billable and how many hours are not project related. So, the billable and non-billable hours are from your project time; not project related hours are attendance time records. Please note that if you connected the project time with the attendance time your productivity rate will be 100% all the time since the project time is the same than the attendance time.
You can get a quick overview about the productivity also with the dashboard widget →
