如何應用五個為什麼方法
Here’s a step-by-step guide on how to apply the Five Whys approach:
1/ 確定問題:
首先明確定義您要解決的問題。 確保問題是具體的並且每個相關人員都能很好地理解。
2/ Formulate the First “Why” Question:
詢問為什麼會出現問題。 鼓勵團隊成員提供探索問題直接原因的回應。 這將啟動調查過程。
3/ 對每個答案重複:
For each answer to the initial “why” question, ask “why” again. Continue this process iteratively, typically five times or until you reach a point where the responses lead to a fundamental cause. The key is to go beyond surface-level explanations.
4/分析根本原因:
Once you’ve asked “why” five times or have identified a root cause that resonates with the team, analyze it to ensure it is indeed the fundamental issue. Sometimes, additional investigation or validation may be necessary.
5/ 制定解決方案:
確定根本原因後,集思廣益並實施直接解決問題的解決方案。 這些解決方案應旨在消除或減輕根本原因,並防止問題再次發生。
6/ 監控和評估:
Let’s put our solutions into action and keep a close eye on their impact as time goes on. Evaluate whether the problem has been resolved and whether any adjustments to the solutions are necessary.

五個為什麼的例子
Let’s walk through a simple example of the Five Whys approach to illustrate how it works. Imagine a scenario where your marketing team is facing an issue: Website Traffic Decreased
問題陳述:網站流量減少
1.為什麼網站流量下降了?
- 答:跳出率明顯上升。
2.為什麼跳出率增加了?
- 答:訪客發現網站內容不相關。
3. 為什麼訪客發現內容不相關?
- Answer: The content didn’t align with the current needs and preferences of the target audience.
4. Why didn’t the content align with the audience’s needs and preferences?
- Answer: The marketing team didn’t conduct recent market research to understand the evolving customer preferences.
5. Why didn’t the marketing team conduct recent market research?
- Answer: Limited resources and time constraints hindered the team’s ability to conduct regular market research.
根本原因: 網站流量下降的根本原因是有限的資源和時間限制阻礙了行銷團隊進行定期的市場調查。
解決方案: 分配專門的資源進行定期市場研究,以確保內容符合目標受眾不斷變化的需求和偏好。
在這個行銷範例中:
- 最初的問題是網站流量減少。
- By asking “why” five times, the team identified the root cause: limited resources and time constraints hindering regular market research.
- 該解決方案涉及透過專門為定期市場研究分配資源來解決根本原因,以便更好地使內容與受眾偏好保持一致。
成功應用「五個為什麼」方法的技巧

- 鼓勵開放式溝通: 為團隊成員創造一個安全的空間來分享他們的見解,而不必擔心受到指責。 強調過程的協作性質。
- 記錄過程: 記錄五個為什麼分析,包括提出的問題和提供的答案。 該文件對於將來的參考和學習很有價值。
- 根據需要進行調整: Be flexible in the application of the Five Whys. If the team identifies the root cause before asking “why” five times, there’s no need to force additional questions.
