4>* PERT ha!t

Complex projects require a series of activities, some of which must be performed

sequentially and others that can be performed in parallel with other activities. This

collection of series and parallel tasks can be modeled as a network.

The Program valuation and !eview Technique "P!T# is a network model that

allows for randomness in activity completion times. P!T was developed in the late

$%&'(s for the ).*.

+avy(s Polaris project having thousands of contractors. t has the potential to

reduce both the time and cost required to complete a project.

P!T is a method to analy-e the tasks involved in completing a given project,

especially the time needed to complete each task, and identifying the minimum

time needed to complete total project.

P!T event/ is a point that marks the start or completion of one or more tasks. t

consumes no time and uses no resources. t marks the completion of one or more

tasks, and is not 0reached0 until all of the activities leading to that event have been

completed.

predecessor event/ an event "or events# that immediately precedes some other

event without any other events intervening. t may be the consequence of more

than one activity.

successor event/ an event "or events# that immediately follows some other event

without any other events intervening. t may be the consequence of more than one

activity.
