PERT Chart Overview and Creation

Oct 20, 2025

Summary

  • The meeting provided an overview of how to create a PERT (Program Evaluation Review Technique) chart, its history, and key distinctions from related project management methods.
  • Participants discussed the rules and visual elements of PERT charts, specifically the use of arrows for activities and nodes for milestones.
  • A step-by-step example demonstrated building a PERT chart, highlighting the significance of precedence diagrams.
  • The importance of using project management tools for complex charts was mentioned, with a brief software suggestion.

Action Items

  • (No action items were identified in the transcript.)

Introduction and Background of PERT Charts

  • PERT stands for Program Evaluation Review Technique and was created in the 1950s by the US Navy for the Polaris submarine missile project.
  • The critical path technique, a similar project management method, was developed independently in the private sector.
  • Both methods are used for planning, scheduling, and controlling projects.

Rules and Structure of PERT Charts

  • In PERT charts, activities (tasks) are depicted as arrows.
  • Milestone dates are represented as nodes (circles) in the diagram.
  • This structure is referred to as the "activity on arrow" method.

Example and Precedence Diagrams

  • A basic example showed an activity ("collect project data") on an arrow, with milestone nodes at each end and the duration noted.
  • Expanding to larger projects, the diagram becomes more complex, showing multiple activities branching from a single milestone node.
  • Precedence diagrams illustrate that certain activities must be completed before subsequent activities begin.

Use of Tools for PERT Chart Creation

  • Manual creation of PERT charts is possible but can be challenging for complex projects.
  • Using a project management tool (such as ProjectManager.com) is recommended to simplify and streamline the process.

Decisions

  • (No decisions were made during the meeting.)
