They are defined so that every member involved in a project can immediately understand “who executes a task, who makes the final decision, who to consult, and who to report progress to.”<\/p>\n\n\n\n Assigning these roles correctly is essential for running a project smoothly.<\/p>\n\n\n\n “R” refers to the person responsible for execution \u2014 the role that actually carries out the assigned task.<\/strong><\/span> The responsible person is the team member who performs the concrete work needed to complete the task. In a RACI chart, it is generally recommended to limit the responsible person to one individual, although depending on the nature of the project, multiple people may share this role.<\/strong><\/span> “A” is the accountable person \u2014 the role that bears ultimate responsibility for the completion of a task.<\/strong><\/span> This role is often filled by a project owner or manager, and involves approving the task and making final decisions. “C” means consulted \u2014 the role of someone whose opinions and specialist advice are sought during task execution.<\/strong><\/span> This role is often filled by members with specialized knowledge or representatives from related departments. “I” refers to the informed person \u2014 the role that receives updates on task progress and completion reports.<\/strong><\/span> This person is not directly involved in executing the task, but needs to stay aware of relevant information and outcomes.<\/p>\n\n\n\n Examples include a supervisor who needs to track project progress, or members of another department responsible for downstream work. Implementing a RACI chart offers many advantages in project management. It not only clarifies roles and responsibilities, but also facilitates smoother communication within the team and contributes to greater operational efficiency.<\/p>\n\n\n\n Here we explain three representative benefits.<\/p>\n\n\n\n The greatest benefit is that the person in charge and the locus of responsibility for each task become immediately clear.<\/strong><\/span> Because it is clear who executes a task and who bears final responsibility, situations such as “no one knows whose job this is” or “people are waiting for instructions” are prevented. A RACI chart clarifies communication paths \u2014 who to consult and who to report to.<\/strong><\/span> This reduces unnecessary confirmation work and missed reports, and improves the speed of decision-making.What is a RACI Chart? A Framework for Clarifying Role Assignments in a Project<\/h2>\n\n\n\n
The Four Roles and Scope of Responsibility in a RACI Chart<\/h2>\n\n\n\n
\n
R (Responsible): The Person Who Executes the Task<\/h3>\n\n\n\n
For example, for a task such as “create the website design,” a designer would fill this role.<\/p>\n\n\n\nA (Accountable): The Person Who Makes the Final Decision and Owns the Outcome<\/h3>\n\n\n\n
As an important rule, only one person may be assigned as accountable for each task.<\/strong><\/span> This ensures clarity of responsibility and prevents confusion in the chain of command.<\/p>\n\n\n\nC (Consulted): The Person Whose Input Is Sought<\/h3>\n\n\n\n
They provide important information that shapes the quality and direction of the task, but do not hold decision-making authority.<\/strong><\/span> A key characteristic of this role is that it requires two-way communication.<\/p>\n\n\n\nI (Informed): The Person Who Receives Progress Updates and Results<\/h3>\n\n\n\n
Communication in this role is fundamentally one-directional reporting.<\/p>\n\n\n\n3 Benefits of Implementing a RACI Chart<\/h2>\n\n\n\n

<\/figure>\n\n\n\n\n
Benefit 1: Clarifies Who Is Responsible for What<\/h3>\n\n\n\n
This allows each member to focus on their own role and encourages proactive action.<\/p>\n\n\n\nBenefit 2: Promotes Smooth Communication<\/h3>\n\n\n\n
Because everyone involved knows “who to ask about what,” information flows smoothly within the project, and the risk of rework is also reduced.<\/p>\n\n\n\nBenefit 3: Prevents Duplication of Work and Missed Tasks<\/h3>\n\n\n\n
