Which elements can monitor an active project's progress?

The Gantt chart, project conditions, and metrics are integral to effectively monitoring an active project's progress.

The Gantt chart visually represents the project schedule, showing the start and end dates of tasks and their dependencies. This allows project managers and stakeholders to see the timeline and track whether the project is on schedule, behind, or ahead of time.

Project conditions refer to predefined parameters or criteria that indicate the state of the project. These conditions can include thresholds for performance, completion of key milestones, or specific project health indicators. Monitoring these conditions helps in evaluating the overall health of the project and determining if corrective actions are necessary.

Metrics provide quantifiable measures that can reveal insights into various aspects of the project, such as performance, resource utilization, and time management. By analyzing these metrics, project managers can gauge progress and make data-driven decisions to steer the project toward successful completion.

The other options, while they might contain relevant elements for managing a project, do not focus specifically on monitoring progress in the same comprehensive manner as the Gantt chart, project conditions, and metrics.
