The mechanics of a flow-accounting system are not very complex. Instead of logging hours, people log uninterrupted hours. In order to get honest data, you have to remove the onus from logging too few uninterrupted hours. People have to be assured that it’s not their fault if they can only manage one or two uninterrupted hours a week; rather it’s the organization’s fault for not providing a flow-conducive environment. Of course, none of this data can go to the Payroll Department. You’ll still have to retain some body-present time-reporting for payroll purposes.
