Notes 9.5 Analysis on Activity Network

One of the ‘second seven tools’, this is a typical project planning tool for piecing together a
multi-task complex set of interdependent activities. It allows you to calculate what task starts
when, what float there is in the project, etc.
Also called an ‘Activity-on-Node Diagram’, the option (but potentially more troublesome)
method of doing this is with an ‘Activity-on-Arrow Diagram’, or simply ‘Arrow Diagram’.

An 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 recognize 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.
Activity Network Diagrams ongoing out as an engineering and construction project management
tool. Critical Path Analysis draws on this methodology to identify and standardize medical
management activities.
An Activity Network Diagram helps to find out the most competent sequence of events needed
to complete any project. It enables you to create a realistic project schedule by graphically
showing
1. The total amount of time needed to total the project

2. The sequence in which tasks must be carried out
3. Which tasks can be carried out at the same time
4. Which are the critical tasks that you need to keep an eye on.
It was urbanized 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 managers.
