The Linear Responsibility Chart:
The Linear Responsibility Chart (LRC), also known as the Responsibility Assignment Matrix (RAM), is another visual depiction of the roles and responsibilities on a project. These charts list tasks on one axis and the responsible persons or departments on the other. Often a coding system (such as a set of symbols) is used to indicate the type of responsibility of each person or department for each task.

The LRC to the left is a simple example for procurement of raw materials on a project. This example is taken from a real project. We recommend that when you build your own LRC, you use the names of individuals rather than their titles. This is consistent with the intended behavior of accountability.
