During a major cost-cutting initiative, senior management requests a report showing the remaining work for outstanding projects. Which tool should the project manager use?

A burndown chart visually represents the remaining work over time, making it ideal for showing senior management the progress and outstanding tasks in a cost-cutting initiative. It clearly depicts the amount of work left to be done against the time available. Forecast estimation is a technique, not a tool, used to predict future project performance. Earned Value (EV) measures the value of work completed but doesn't directly show remaining work in a simple, visual format for this purpose. A cumulative flow diagram tracks work in progress and completed work but is more complex and less direct for simply showing "remaining work" than a burndown chart.
