What is a recognizable reference point used to monitor progress called?

A recognizable reference point used to monitor progress is known as a milestone. Milestones are key markers in a project that signify important stages or accomplishments. They help in tracking progress and ensuring that the project is on schedule. Milestones can represent the completion of significant phases or deliverables in a project, allowing stakeholders to evaluate whether objectives are being met and to identify any necessary adjustments.

While events can indicate occurrences in a project, they do not necessarily serve as reference points for measuring progress. Deadlines are specific due dates for tasks but do not serve as indicators of completed progress along the project's timeline. Benchmarks provide a standard or reference point for comparison but are more focused on performance metrics rather than specific progress indicators. Therefore, recognizing milestones is crucial for effective project monitoring and management.
