Final answer:
A Kanban board is the project management tool that uses columns labeled To Do, In Progress, and Done to organize tasks, unlike RACI charts, Gantt charts, or Work Breakdown Structures (WBS).
Step-by-step explanation:
The project management tool that organizes tasks into columns with labels such as To Do, In Progress, and Done is known as a Kanban board. A Kanban board is a visual tool that helps track the progress of work and is widely used in agile project management and other organizational methods. It provides a clear, at-a-glance view of workload and work flow, facilitating better communication and efficiency among team members. Unlike the RACI chart, which defines roles and responsibilities, or the Gantt chart, which schedules project timelines, or the Work Breakdown Structure (WBS), which is a hierarchical decomposition of the total scope of work, the Kanban board focuses on the current work status.
