It’s typical that when the first question regarding an issue is asked, the response is automatic, usually giving an excuse as to why something became an issue. Participants usually get right to the root cause of the issue when they are
asked “why” multiple times; excuses get peeled away. The other responses are incorrect. The exercise is for analyzing the root cause, not to hide issues or shift blame; the approach isn’t looking for five reasons, but root cause analysis;
it isn’t looking for the opinions of five project team members, but is looking for root cause analysis.
