How do milestone charts differ from network diagrams in purpose and use?

• A. Milestone charts show key events with dates; network diagrams show task relationships and dependencies
• B. Milestone charts show budgets; network diagrams show communication lines
• C. Milestone charts show risks; network diagrams show channels
• D. Milestone charts show resources; network diagrams show milestones

Answer: (A)

Milestone charts and network diagrams serve different purposes in project planning: milestone charts highlight key events with target dates to track progress, while network diagrams map the sequence of work by showing task relationships and dependencies. A milestone chart focuses on significant points in time—moments when a deliverable or approval is due. It helps you communicate progress to stakeholders and see whether the project is hitting major dates. It doesn’t show how long tasks take or how they must be ordered; it’s about the calendar milestones you need to reach. A network diagram, on the other hand, is a scheduling tool that lays out activities and the logical relationships between them. It shows which tasks depend on others, the flow of work, and how delays in one activity affect others. This makes it useful for analyzing sequencing, identifying the critical path, and calculating earliest finish dates. That contrast—dates and milestones versus task relationships and dependencies—is what sets them apart. The other options describe different concepts (budgets, communication lines, risks, channels, resources) that aren’t the primary purpose of these two chart types.
