Which technique is commonly used to identify root causes of recurring problems?

• A. The 5 Whys technique or root-cause analysis.
• B. Rapid brainstorming without data.
• C. Assigning blame to team members.
• D. Relying on luck.

Answer: (A)

Identifying the underlying reason a problem keeps happening is the goal. The 5 Whys technique is built for that purpose: start with the problem, ask why it occurred, then take the answer and ask why again, and repeat until you reach a root cause that explains the recurring issue. This approach moves beyond surface symptoms to address the fundamental process or system issue, and it guides you to effective countermeasures that prevent repetition rather than quick fixes. Other options don’t fit this purpose as well. Rapid brainstorming without data might generate ideas, but it isn’t a structured method for uncovering root causes and can lead to guesses rather than verified causes. Assigning blame to individuals undermines problem-solving and won’t reveal systemic reasons. Relying on luck is not a method and offers no reliable path to preventing recurrence. In practice, teams often combine the 5 Whys with other tools to map possibilities and verify root causes with evidence.
