Put one task per row on the Tasks tab: what it is, who owns it, priority, status, start and due dates, and how far along it is (%). Days left and a plain-English flag — OVERDUE in red, Due soon in amber, On track, or Done — work themselves out from the due date and status. Sort by the flag each morning and you always know what to push.
The Dashboard shows how many tasks are done, in progress and overdue, your overall completion, and a breakdown by status with a chart. Set today's date to keep the flags current. Yellow cells for typing; the flags and totals are locked formulas. Opens in Excel or Google Sheets.
