The document provides guidance on performing a root cause analysis (RCA) as part of a performance improvement project (PIP) following an adverse event. It outlines 7 steps for conducting an RCA: 1) select the event and gather information; 2) charter a team and select members; 3) describe what happened by creating a timeline; 4) identify contributing factors; 5) identify root causes by asking "why" questions of contributing factors; 6) design changes to eliminate root causes; and 7) measure success of changes. The document emphasizes identifying systems issues rather than individual performance, getting perspectives of those involved, and using a timeline to guide analysis to thoroughly investigate the underlying causes.
