An Activity Network Diagram is also called an Arrow Diagram or a PERT Diagram. You can draw the activity network diagram easily with Edraw software.
Activity Network Diagram
Activity Network Diagram
(AND) is also called an Arrow Diagram (because the pictorial
display has arrows in it) or a PERT (Program Evaluation Review
Technique) Diagram, and it is used for identifying time
sequences of events which are pivotal to objectives. In Critical
Path Analysis this helps the teams to comprehend specific event
sequences driving time requirements for objective achievement.
Activity Network Diagrams are also very useful when a project
has multiple activities which need simultaneous management.
Network Diagrams started out as an engineering and construction
project management tool. Critical Path Analysis draws on this
methodology to identify and standardize medical management
Network Diagram helps to find out the most efficient sequence of
events needed to complete any project. It enables you to create
a realistic project schedule by graphically showing
- the total amount of
time needed to complete the project
- the sequence in
which tasks must be carried out
- which tasks can be
carried out at the same time
- which are the
critical tasks that you need to keep an eye on.

Example of Activity Network Diagram
A project is composed of a set of actions
or tasks which usually have some kind of interdependency. For
example, before an axle can be turned, it must first be
designed, the metal must be purchased, etc. This type of complex
system is much easier to understand through the use of diagrams
than through textual description, as actual interconnections
between tasks can be shown. You can draw the activity network
diagram easily with Edraw software.
The Activity Network diagram displays
interdependencies between tasks through the use of boxes and
arrows. Arrows pointing into a task box come from its
predecessor tasks, which must be completed before the task can
start. Arrows pointing out of a task box go to its successor
tasks, which cannot start until at least this task is complete.
Activity Network Diagram Drawing Rule
All the preceding activities must be
completed before the project can begin.
The arrows represent the logical precedence
of the project.
History of Activity Network Diagram
It was developed by the U.S. Department of
Defense. It was first used as a management tool for military
projects. It was Adapted as an educational tool for business
