Now it's time to update the schedule with the information about the tasks completion in terms of duration or work. Fill in the corresponding column (% complete for duration and % work complete for work) with the values given to you by the people responsible with the project execution. If the completion value is related to a status date (date coresponding to the completion value), than the task have to be moved until the end of the dark coloured part of the taskbar is approximately at the status date. To increase the accuracy it might be necessary to change into another scale and make the adjustments because the task movement is posssible only by entire bottom units.

The completed part of the task is highlighted in the Gantt graph with a darker color. If necessary, you can move the task so the end date of the completed part to correspond with the status date of the completion.

The % complete value for a task can be also modified in the Gantt graph by moving the mouse cursor in the left side of the uncompleted part of the task until the cursor appear and dragging on the right side to increase, or the left side to decrease it.

If there are resources assigned to tasks, by changing either % complete or % work complete, the other parameter will be calculated automatically. Otherwise, there is no work to calculate.
