Add a quantity to a task

Quantify a task as a physical count, such as 3 columns, so you can update its progress in units instead of percentages.

Quantify a task when its progress is easier to count than to estimate as a percentage. For example, a task to build 3 columns, one per day, can be quantified as 3 columns. You then enter progress as 1 column for the day, not 33.33%.

The quantity is spread equally over the task's days automatically. You cannot allocate it by hand.

Total Quantity and Unit set for the task

To undo it, click Remove Quantity. It shows only before the task starts.

When you can quantify a task

  • You can add a quantity only when the task is not committed and has not started. Completed tasks cannot be quantified.
  • To quantify a task, uncommit it first: turn off the Commit switch in the task's widget or Detailed View. A started task cannot be uncommitted. A committed task with no quantity shows Tasks can be quantified only before it starts.
  • If the task already has progress without a quantity, you cannot quantify it part way. You must quantify it from the start, at 0 progress.
