This document discusses using a relationship matrix to identify relationships between root causes and environmental concerns when developing solutions. It involves transferring identified critical issues from a root cause identification matrix to the column headers of a relationship matrix. Then the team identifies any environmental issues that must be considered for each root cause and marks them with a "Y" in the appropriate cell. Once complete, the issues are described on a separate tab to inform countermeasure development. The goal is to improve the environmental performance and profile of the organization while addressing root causes.
