Some organizations use a chart that lists project tasks and milestones vertically and project members horizontally. Each task is mapped to everyone involved in the project through samples (R, A, C, I).

For example, in a project there are three tasks and three members.

First, preparing a bill of martials task and prepare estimate task must be the responsibility of the project team, while the project manager is considered accountable of these tasks. For the Preparing estimate task, the sponsor must be informed. For the third task, sending procurement document task is the responsibility of the project manager, while the project team is accountable of this task, in the other hand the sponsor indeed must be informed in this task.

What is the name of this chart, and what (R, A, C, I) stand for?

Based on the above example create the chart in a table
