Tracking the project
Now it's the 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 provided to you by the people
in charge with tasks' execution. The completed part of a task will be rendered with a darker color in the Gantt chart.
The
% complete value for a task can also be modified in the Gantt chart
by moving the mouse cursor over the left side of the uncompleted part of the task until the

cursor appears and by dragging towards the right side to increase it or the left side to decrease it.
If there are resources assigned to tasks, by changing either the
% complete
or the
% work complete, the other parameter will be computed automatically.
Otherwise there is no work to be computed.
Hint: At the controlling phase's start, before making any changes
involved by the project tracking it can be useful to save a baseline (Baselines menu,
Save... action). This will help you to compare the updated schedule at a later stage with the planned schedule.
