When creating timelines, what type of markers must be included?

In the context of creating timelines, milestones are essential markers that signify key events or achievements within a project or process. They serve as significant checkpoints that help track progress and indicate when certain goals have been reached. Each milestone represents a critical point that can help assess whether the project is on schedule, ahead of time, or facing delays.

For example, in a project timeline, a milestone could be the completion of a planning phase, the approval of a design, or the completion of a major construction milestone in fire tactics training scenarios. Including milestones in a timeline allows teams to have a clear understanding of their progress and facilitates efficient management of resources and personnel involved.

While other types of markers, such as completion, impact, or resources, may play roles in broader project management, they do not specifically serve the same function as milestones do in indicating pivotal stages of progress. Therefore, highlighting milestones is vital for effective timeline creation and project tracking.
