Guide: RACI Matrix

The RACI Matrix, pronounced ‘ray-see,’ stands as a cornerstone in effective project and stakeholder management. This essential tool provides a structured and clear approach to defining and communicating the roles and responsibilities within a project. Comprising four key categories: Responsible, Accountable, Consulted, and Informed the RACI Matrix categorizes stakeholder involvement and decision-making authority at pivotal stages of a project.

Its implementation ensures improved communication, enhanced accountability, and clarity of roles, making it an indispensable element in managing complex projects efficiently.

What is a RACI Matrix?

The RACI (pronouced ray-see) Matrix is a key tool for stakeholder management in projects. This tool provides a structured approach to defining and communicating roles and responsibilities within a project. RACI is an acronym for Responsible, Accountable, Consulted, and Informed. This is used to categorize the level of involvement and decision-making authority of a stakeholder at key stages of a project. This allows for improved communication, enhanced accountability, and role clarity. 

RACI Matrix

Within the RACI Matrix, there are two key elements: tasks and activities on one axis and stakeholders on the other axis. The matrix then states for that role if the stakeholder is responsible for the activity, accountable for the activity, consulted about the activity, or just is just informed about the activity.

Understanding the RACI Components

When using a RACI matrix, it is important to understand the differences between the 4 stakeholder assignment labels to ensure you assign them to stakeholders correctly and have the right stakeholder involvement a key stages of the project to ensure effective stakeholder management.


The first element is ‘Responsible’. It refers to stakeholders who are tasked with actually completing the work associated with it. For every task or decision in a project, there should be one person assigned as responsible. This ensures that there is no confusion about who is expected to carry out the work, leading to improved efficiency and effectiveness. There may be tasks that require multiple people to do; even then, there should be one person who is assigned responsibility for the activity.


The next component of a RACI Matrix is ‘Accountable’ This is the person who may not be involved in the execution of the task but is ultimately accountable for its successful completion. The stakeholder who is accountable is the one who must sign off on or approve the work performed by the responsible party.

Usually, this role is taken by project managers, team leads, or other higher-level stakeholders. The key aspect here is that, while there can be multiple people Responsible for different parts of a task, there should only be one Accountable person. This ensures a clear line of accountability and decision-making authority.


Next, we have the ‘Consulted’ category; these are those stakeholders whose opinions and expertise are needed during the decision-making process. These are often subject-matter experts who can provide valuable insights and advice that guide responsible and accountable stakeholders in their work. Their role is important, as they often contribute significantly to the planning and detail-oriented aspects of a task, ensuring that the team benefits from a broader range of knowledge and expertise.


Finally, we have ‘Informed’ stakeholders; this group consists of those who need to be kept up to date on processes or decisions but are not involved in the execution of tasks. These individuals might be affected by the outcomes of the tasks or may require information for other related responsibilities. Communication with informed individuals is typically one-way.

The purpose of keeping them informed is to maintain transparency and ensure that everyone who needs to be aware of the project’s progress and critical decisions is appropriately updated. This is a key element of stakeholder and change management to ensure resistance to change is kept to a minimum.

Implementing a RACI Matrix

Step 1: Identify All Tasks and Processes

The first step in implementing a RACI matrix requires identifying all of the tasks, milestones, and key decisions that will be part of the project. This step sets out the basis for assigning roles and responsibilities.

Start by listing all the tasks that need to be done for the project to be successful. This will include everything from high-level tasks like project plans and design, to smaller tasks such as coding a specific feature (in a software project) or preparing a report. 

You will also need to identify significant milestones within the project timeline. These are key points in a process where a certain aspect should be completed or reviewed. In DMAIC projects, each part (define, measure, analyze, improve, and control) can set project milestones as it marks out a significant step completion before the next step follows.

You will also need to set out any key points where decisions are made within the project, so you can later assign the RACI categories to these.

This will form your Y Axis on the RACi Matrix

Step 2: Determine the Project Roles

Next, we need to identify all of the roles or stakeholders involved in the project. We have an in-depth guide that covers stakeholder management and identification in our guides section, for full details on this process.


However, in this step, you need to list all of the roles involved in the project, from project managers to team members, department heads, and other internal and external stakeholders like clients or vendors.

You will need to conduct a stakeholder analysis to understand the different stakeholders involved, how they are impacted by the project, and where their level of power and influence in relation to the project might be.

Further, you will need to understand the level of involvement each role will have in the project. Some may be deeply involved in day-to-day activities, while others might play a more advisory or oversight role.

This will form the X-axis of your project. In our example, we used role titles, but you may want to use individual names instead, which is also an acceptable method.

Step 3: Assign RACI to Each Task

Now that you have the basis of your X and Y in the RACI matrix, the next step is to complete the matrix. This involves assigning the roles of responsible, accountable, consulted, and informed to each task for each role identified.

For each task, assign who is responsible, who is accountable, who will be consulted, and who needs to be informed. Ensure that each task has one person responsible and one accountable person. The accountable person usually has a higher-level role than the person who is responsible. There can then be an unlimited number of stakeholders who are consulted and informed about each task.

Step 4: Review and Adjust the Matrix

After the initial RACI Matrix is developed, it’s time to review it with the key stakeholders and team members.

During this step, you should discuss it with the project team and other stakeholders to ensure that everyone understands and agrees with the assigned roles and responsibilities. You can then make any necessary adjustments based on the feedback; this could be reassigning roles or clarifying ambiguities.

Step 5: Communicate and Implement

The final step is to communicate the finalized RACI Matrix to all stakeholders and integrate it into the project management process.

Doing this you should share the finalized RACI Matrix and ensure it is kept accessible in a central location that all stakeholders can access. Ideal is a cloud-based system, so when it is updated by the project manager, all stakeholders can be made aware of any changes. Make the RACI Matrix a part of regular project documentation and reference it in meetings and communications. This ensures that roles and responsibilities are always clear as the project progresses.

And finally, regularly refer back to the RACI Matrix throughout the project lifecycle. Update it as necessary to reflect any changes in the project scope, tasks, or team composition.

Additional Useful Information on RACI Matrix

RACI-VS and RASIC: Variations of the Classic RACI

The RACI model has several variations that can provide additional clarity or fit different organizational needs:

  1. RACI-VS: This adds a “Verifier” and a “Signatory” to the standard RACI roles. A Verifier checks the quality of the work, and the Signatory officially approves it.

  2. RASIC: Another variation that includes a “Support” role. In this model, the Support role aids the Responsible party in executing the task but is not ultimately accountable for it.

Why Variations Matter

  1. Enhanced Clarity: Adding roles like Verifier or Support can provide additional granularity, making it easier to manage complex projects.

  2. Increased Accountability: More roles mean a clearer allocation of duties, reducing the chance of tasks falling through the cracks.

Integration with Other Tools

The RACI matrix is often used in conjunction with other project management and continuous improvement methodologies, such as:

  1. Agile: In Agile frameworks like Scrum, a RACI matrix can clarify roles within the team and improve sprint planning.

  2. Lean Six Sigma: RACI can be an effective tool during the Define and Control phases of DMAIC for role definition and sustaining improvements.

Key Tips for a Successful RACI Matrix

  1. Keep It Simple: While it’s tempting to add many roles for granularity, keeping your RACI Matrix straightforward will make it more manageable.

  2. Review and Update: As projects evolve, so do roles and responsibilities. Make it a practice to regularly review and update the matrix.

  3. Consult the Team: Before finalizing the matrix, consult with all stakeholders to ensure everyone agrees with their roles and responsibilities.

A: A RACI matrix is a project management tool that helps define roles and responsibilities for each activity or task in a project. RACI stands for Responsible, Accountable, Consulted, and Informed. It provides a clear framework for identifying who is responsible for executing tasks, who is accountable for their success, who needs to be consulted for input, and who needs to be kept informed about progress.

A: A RACI matrix is important because it brings clarity and accountability to project management. It helps avoid confusion by clearly defining who is responsible for each task and who should be consulted or informed. It ensures that all roles and responsibilities are identified and understood, facilitating effective communication, coordination, and decision-making within the project team.

A: To create a RACI matrix, follow these steps:

  1. Define the project scope and identify activities.
  2. Identify project roles and responsibilities.
  3. Determine RACI categories (Responsible, Accountable, Consulted, Informed).
  4. Identify project activities and break them down into specific tasks.
  5. Map activities to roles and assign the appropriate RACI categories for each role.
  6. Create the RACI matrix template with columns for Activity, Responsible, Accountable, Consulted, and Informed.
  7. Fill in the matrix by entering the relevant information for each activity and role.
  8. Review and validate the matrix for accuracy and completeness.
  9. Communicate and implement the matrix by distributing it to stakeholders and team members.
  10. Monitor and update the matrix as needed throughout the project.

A: Yes, a role can have multiple RACI assignments. Depending on the project’s complexity, a role may be responsible for executing certain activities, accountable for the success of other activities, and consulted or informed for additional tasks. The RACI matrix allows for flexibility in assigning different levels of involvement to each role based on the specific activities.

A: The RACI matrix should be regularly reviewed and updated throughout the project’s lifecycle. As the project evolves, roles may change, new activities may emerge, or priorities may shift. It is important to monitor the progress of the project, assess any changes or updates to roles and activities, and update the RACI matrix accordingly. This ensures that the matrix remains accurate and reflective of the current project status, supporting effective communication and accountability.

A: Yes, the RACI matrix can be used in various project management methodologies, including Agile, Waterfall, and hybrid approaches. It provides a universal framework for defining roles and responsibilities, irrespective of the methodology being followed. The RACI matrix helps teams and stakeholders understand who is responsible, accountable, consulted, and informed at each stage of the project, promoting collaboration and clarity regardless of the specific project management approach.
