or by task duration. It is useful to take into account the time sequence as soon as a
task is entered. This will facilitate graphical presentations later.
On the left hand side we have a running number allocated by the system. The
next row contains the task name in long text. This is followed by the start date.
When dates are allocated the system will issue a warning when a proposed date does
not exist (for example November 31st) or when it coincides with a Sunday or a
public holiday. Thereafter the task duration can be entered so that the end date will
be calculated. But it is also possible to define the end date, and the system then
calculates the task duration. However, it is not possible to fix the duration and then
trying to allocate an implausible end date.
The task can then be displayed in detail (Fig.
10.2
) and supplemented with
additional information.
For reasons of simplification the other rider options will not be followed through
here. Basically the detailed presentation repeats the data from the task list. In
addition a field showing the percentile of completion of that task appears. This
field can be updated manually.
10.3.2 Gantt Diagram
The Gantt diagram shows in a well arranged fashion the most important project
scheduling and progression data in one single chart (Fig.
10.3
):
The task itself along with its name
Task duration
Start date of the task and
End date of the task.
At the same time a configurable calendar is displayed along the x-axis at the top.
If necessary a second calendar can be shown with a different scale. In this way
months can be depicted at the top und weeks on the second line or weeks above and
days below. Below this calendar individual tasks are shown as time bars.
