ABSTRACT
Program (Project) Evaluation and Review Technique (PERT)(G) is a project management tool used to schedule, organize, and coordinate tasks within a project. It is basically a method to analyze the tasks involved in completing a given project, especially the time needed to complete each task, and to identify the minimum time needed to complete the total project. PERT planning involves the following steps:
Identify the specific activities and milestones. Determine the proper sequence of the activities. Construct a network diagram. Estimate the time required for each activity. Determine the critical path. Update the PERT chart as the project progresses.
KEYWORDS
Program Evaluation and Review Technique (PERT), nodes, PERT event, predecessor event, successor event, PERT activity, Optimistic time, Pessimistic time, Most likely time, Expected time, Critical Path, Lead time, Lag time, Slack.
OBJECTIVE
The main objective of PERT is to facilitate decision making and to reduce both the time and cost required to complete a project.
FIELD OF APPLICATION
PERT is intended for very large-scale, one-time, non-routine, complex projects with a high degree of intertask dependency, projects which require a series of activities, some of which must be performed sequentially and others that can be performed in parallel with other activities.
RELATED TOOLS
Critical Path Method (CPM), Gantt chart

DESCRIPTION
PERT planning involves the following steps that are described below. 1. Identify the specific activities and milestones. The activities are the tasks required to complete a project. The milestones are the events marking the beginning and the end of one or more activities. It is helpful to list the tasks in a table that in later steps can be expanded to include information on sequence and duration. 2. Determine the proper sequence of the
