Signing off on a time heet on a weekly basis allows for work to be approved and integrated into the work schedules.
In addition to entering time as it really happened, it is also necessary for contributors to sign and submit their timesheet in a timely manner. This ensures that the work manager has a complete view of the current progress on a project before making schedule adjustments or distributing status reports to project sponsors and executive management. Planview recommends that timesheets be signed on a weekly basis after all time has been reported for a given week.
