The Responsibility Assignment Matrix - RAM | PMP

Responsibility Assignment Matrix

Yad Senapathy, PMP December 21, 2022

The responsibility assignment matrix, also known as RAM, is a helpful tool used in project management to identify and clarify the roles and responsibilities of each team member. It ensures that every team member understands their duties and how they fit into the project plan. Using RAM in project management helps define roles and responsibilities within a project team and avoids confusion or overlap. Besides these things, the Responsibility Assignment Matrix also helps improve communication and coordination within the team, leading to a more successful project outcome.

What is RAM in project management?

A RAM consists of a grid with four columns: responsible, accountable, consulted, and informed also known as a RACI chart. Each row on the grid represents a specific task or activity within the project, and each column represents a role or responsibility. To help you understand these four columns, we have explained them below.


This column represents the person or team responsible for completing the task. They are the ones who will do the work.


This column represents the person or team ultimately accountable for completing the task. They may not be doing the work themselves, but they are responsible for ensuring it gets done.


This column represents the people or teams who need to be consulted or informed about the task before it is completed. They may have input or expertise that can help in completing the task effectively.


This column represents the people or teams who need to be informed about the task once it is completed. They may not have direct involvement in the task, but they need to be kept in the loop for various reasons.

Things to Consider When Creating a RAM or a RACI chart

If you’re creating a RAM, here are a few key considerations to keep in mind.

  • Ensure the roles and responsibilities are clearly defined: It is vital that everyone on the team understands their specific duties and how they fit into the project plan. If there is any confusion or uncertainty, it can lead to delays or mistakes.
  • Ensure accountability: The person or team in the accountable column should be identified, as they are ultimately responsible for ensuring that the task is completed successfully.
  • Be mindful of overlap: Avoiding overlap or duplication of responsibilities within the team is important. If multiple people or teams are responsible for the same task, it can lead to confusion and potentially create unnecessary bottlenecks.
  • Use it as a living document: A RAM is not a static document, as it should be updated with the change in roles and responsibilities and the progress made in the project. Make sure to regularly review and revise the RAM as needed to reflect the project’s current state accurately.

Example of Responsibility Assignment Matrix (RAM)

Following is an example of a responsibility assignment matrix for a new product launch project.

Task Responsible Accountable Consulted Informed
Conduct market research Marketing team Product manager Sales team Executive team
Design product packaging Design team Product manager Marketing team Executive team
Source materials for production Procurement team Product manage Design team Executive team
Set up production line Operations team Product manager Procurement team Executive team
Create marketing campaign Marketing team Product manager Sales team Executive team

In this example, the product manager is the one who is ultimately accountable for the success of the project, while the various teams are responsible for completing specific tasks. The marketing, design, procurement, and operations teams are all responsible for their respective tasks, and they are also consulted or informed as needed by other teams. The executive team is kept informed of the project’s progress.

To sum it up, the responsibility assignment matrix RAM also known as a RACI chart is a valuable tool for any project manager to have in their toolkit. It helps to clearly define roles and responsibilities within a team, which ultimately leads to a more successful outcome for any project.
