A BPMN Resources Usage Matrix is designed to review and edit an allocation of Resource Roles for BPMN Activities. The Resource Roles used in an Activity show a Resources property in a BPMN Activity specification dialog.
A BPMN Resources Usage Matrix presents information about BPMN Activities in rows and Resource Roles in columns. Each arrow in the matrix shows if a Resource Role is used by an Activity. You can define Resource Roles usage for all BPMN Activities by assigning or removing the Resource Roles to or from the Activities.
