Which scheduling tool is described as a horizontal bar chart?

### Why this is right A Gantt chart is described as a horizontal bar chart used as a production control tool and frequently used in project management. ### The concept A bar-chart representation can show project activities across time. It differs from a WBS, which decomposes work hierarchically, and from CPM, which analyzes activity relationships and project duration. ### The other options - **B. Work Breakdown Structure (WBS)**: This is a hierarchical breakdown of project work, not the horizontal bar chart described. - **C. Critical Path Method (CPM)**: This is an activity-oriented scheduling technique. - **D. Risk item checklist**: This supports risk identification, not schedule display. ### Terms - **Gantt chart**: A horizontal bar chart used in project scheduling and control. - **Production control**: Organizing and tracking the work needed to produce an output. ### Remember Bars across a schedule indicate a Gantt chart.
