Completion status refers to the current state of a task or project, indicating whether it is finished, in progress, or not started. It helps individuals and teams track their progress and manage their time effectively. Common statuses include "Not Started," "In Progress," and "Completed," which provide a clear overview of where things stand. In project management, completion status is often displayed in tools like Gantt charts or Kanban boards. These visual aids allow team members to quickly assess the progress of various tasks and identify any potential delays or bottlenecks, ensuring that projects stay on track and deadlines are met.
