FAQ
Frequently Asked Questions
What is a PERT chart?
A PERT (Program Evaluation and Review Technique) chart is a project management diagram that maps tasks as nodes connected by arrows showing dependencies. Each task includes three time estimates — optimistic, most likely, and pessimistic — to calculate an expected duration. The chart reveals the critical path: the longest sequence of dependent tasks that determines the project's minimum completion time.
How does the AI PERT chart generator work?
You describe your project in plain language or enter tasks manually. The AI identifies task names, assigns logical dependencies, and suggests realistic three-point time estimates. It then renders a fully connected PERT network diagram with the critical path highlighted. You can refine any task, estimate, or visual setting and see the chart update instantly.
What is the difference between a PERT chart and a Gantt chart?
A Gantt chart displays tasks on a calendar timeline as horizontal bars, making it easy to see start and end dates. A PERT chart focuses on task dependencies and the network of relationships, showing which tasks must finish before others can begin. PERT charts are better for analyzing schedule risk and finding the critical path; Gantt charts are better for tracking day-by-day progress.
How is expected time calculated in a PERT chart?
The standard PERT expected time formula is: Expected Time = (Optimistic + 4 × Most Likely + Pessimistic) ÷ 6. This weighted average accounts for uncertainty by giving the most likely estimate four times more weight. MakeCharts applies this formula automatically for every task as soon as you enter the three time values.
Can I use this free online PERT chart generator without signing up?
Yes. You can generate, customize, and download a PERT chart without creating an account. Free users also receive AI credits to try AI-powered generation. Signing up unlocks saved charts, more AI credits, and advanced export options.
How do I add task dependencies in the PERT chart tool?
In the configuration panel, each task has a 'Dependencies' field where you select predecessor tasks from a dropdown. The chart automatically draws directional arrows between dependent nodes and recalculates the critical path whenever dependencies change.
What does 'critical path' mean in a PERT diagram?
The critical path is the longest chain of dependent tasks from project start to finish. Any delay on a critical path task directly delays the entire project. Tasks not on the critical path have slack — extra time before they must start. MakeCharts highlights the critical path in a distinct color so you can instantly see where schedule risk lives.
Can I export my PERT chart as a PNG or SVG?
Yes. Download your PERT chart as a high-resolution PNG for presentations and documents, or as an SVG for crisp rendering at any size. SVG export is available on paid plans and is ideal for embedding in websites or large-format prints.
Is there a limit to how many tasks I can add?
Free users can build PERT charts with a generous number of tasks suitable for most projects. Pro and Max plans remove practical limits and support larger, more complex project networks with many tasks and dependencies.
Can I change the time unit from days to weeks or hours?
Yes. The appearance settings let you switch the time unit between days, weeks, and hours. All labels across the chart update automatically — no need to re-enter any values.
