Which of the following chart is important to ensure

A pie chart is a data visualization tool used to show proportional breakdowns of data and has no role in assigning team responsibilities.

A line chart displays data trends over time and is not used to define or communicate roles and responsibilities on a project.

The RACI chart (Responsibility Assignment Matrix) maps every task or deliverable to at least one Responsible owner and one Accountable stakeholder, preventing role ambiguity and ensuring no work item is unowned. It also documents who must be Consulted for input and who must be Informed of outcomes, supporting communication planning. This makes it a critical tool for team alignment and accountability throughout the project.

A Gantt chart is a scheduling tool that shows task timelines and dependencies but does not define who is responsible or accountable for each task.
