Project Schedule Network Diagram Explained | PMP Schedule Logic (with MS Project)

We explore the Project Schedule Network Diagram Technique, a foundational concept for schedule design and analysis in project management. Using a real Hospital EHR Project example, you’ll learn how activities and dependencies form a logical network — the basis for techniques like the Critical Path Method (CPM). We discuss: How activities and dependencies are represented in a Network Diagram Why Start and Finish nodes are mandatory The role of Work Packages (Summary Tasks in Microsoft Project) Divergence and Convergence nodes — and why they are risk-sensitive How modern tools like Microsoft Project automate network analysis Why documenting sequencing logic is a critical PM responsibility This lesson focuses on understanding the logic, not doing manual math. The PMP exam no longer tests network calculations — but it does test your understanding of how schedules are structured and analyzed. This lesson sets the foundation for upcoming topics like: Critical Path Method Schedule optimization Estimation techniques
