Root Cause Analysis (RCA) is a thorough process to investigate why a problem occurred with a view to taking action to prevent recurrence of this type of problem. It is expensive in terms of people's time and therefore an organization needs to select carefully the issues which are worth doing RCA on. This workshop will examine the process for RCA, including the 'timeline of events' and '5 Whys' tools, and provide an example to aid understanding. Be aware that RCA has a prerequisite - the organization needs to have the discipline to follow a repeatable process, otherwise RCA is just going to add more change to an already ad-hoc environment.
