3.1 Difference between Pert chart and Gantt chart
Characteristics Pert Chart Gantt Chart
Visualization Pert chart as those which helps
in displaying information in the
form of network model.
It is identified that Gantt chart
is present in the format of bar
chart and thus this
presentation is quite helpful in
showing the percentage of
work which is completed.
Simplification Gantt charts are the project that
has very much less interlinking
tasks. In addition to this, it is
found that Gantt charts are easier
Pert chart include tasks as
well as time allocation and
also the display dependency
that makes it little bit

to change. complex. Thus it is quite
difficult to change.
Accuracy Gantt chart are quite simpler to
read and they are more accurate.
It is identified that PERT
chart helps in extending
elements of detail within the
schedule with the ability of the
network model for displaying
various types of dependency.
3.2 Advantages and disadvantages of pert chart and Gantt chart
Advantages
Pert Chart Gantt chart
1. Useful for large project
planning: Pert chart helps in
making large project planning
much easier.
2. Visible critical path: The
critical path generally includes
all the activities which are
generally not delayed
affecting the date of project
completion. Thus Pert helps in
making the critical path visible
clearly.
1. Highly visible: The Gantt
charts are clearly visible and
they clearly evaluate the
activity that needs to be
undertaken for achieving the
objectives.
3. Set realistic timeframes:
The bar helps in indicating the
period in which the activity or
task will be completed

Disadvantages
1. Complicated: Pert chart are
generally considered as
complicated as well as
confusing
2. Inaccurate prediction: In
larger project pert chart does
not provide accurate estimate.
1. The bar size does not
indicate the work amount:
The bar reflects the time
period that is needed for
completing the task
2. They are required to be
updated constantly: Gantt
chart must be updated
regularly.
3.2 Preference between Gantt chart and pert chart
It is identified that Gantt chart are more preferred in comparison to pert chart. This is
because the visualization of Gantt chart is quite higher and therefore they are utilized for
presenting the amount of percentage of work completed. Gantt chart are very much simple and
provide accurate as well as realistic estimation for the project. It is identified that with the help of
the Gantt charts, the resources are allocated properly within the project.
