Network Path

An ordered chain of activities linked by dependencies within a project schedule network diagram.

Key Points

  • A network path is a contiguous sequence of activities connected by dependency relationships.
  • Paths can run from the project start (or a predecessor) to the project finish (or a milestone).
  • The longest network path is the critical path and sets the overall project duration.
  • Float and schedule risk are evaluated by examining and comparing different network paths.

Example

In a software project, one path might be: Define Requirements -> Design -> Develop -> Unit Test -> Integration Test. These tasks form a single network path because each depends on the completion of the previous one.

PMP Example Question

During schedule development, the PM identifies Design -> Code -> Unit Test -> Integration Test as a continuous set of dependent activities. What is this set called?

  1. Work package
  2. Network path
  3. Activity list
  4. Milestone sequence

Correct Answer: B — a chain of dependent activities in the network diagram

Explanation: A network path is an ordered set of activities connected by dependencies; the other options do not represent a dependency-linked sequence.

Advanced Project Management — Measuring Project Performance

Move beyond guesswork and status reporting. This course helps you measure real progress, spot problems early, and make confident decisions using proven project performance techniques. If you manage complex projects and want clearer visibility and control, this course is built for you.

This is not abstract theory. You’ll work step by step through Earned Value Management (EVM), learning how cost, schedule, and scope come together to show true performance. You’ll build a solid foundation in EVM concepts, understand why formulas work, and learn how performance data actually supports leadership decisions.

You’ll master Work Breakdown Structures (WBS), control accounts, and budget baselines, then apply core EVM metrics like EAC, TCPI, and variance analysis. Through a detailed real-world example, you’ll forecast outcomes, analyze trends, and understand contingencies and management reserves with confidence.

Learn how experienced project managers monitor performance, communicate results clearly, and take corrective action before projects slip. With practical exercises and hands-on analysis, you’ll be ready to apply EVM immediately. Enroll now and start managing performance with clarity and control.
