5 Whys
The 5 Whys method helps teams dig beneath surface-level symptoms to uncover the root cause of a problem by repeatedly asking 'Why?' This iterative questioning process reveals deeper insights and facilitates more sustainable solutions.
Use this method when a team is facing a persistent problem and needs to identify the underlying cause before developing effective solutions. It's particularly useful when the initial problem statement feels vague or symptomatic.
Solves: Superficial problem solving that only addresses symptoms, leading to recurring issues.
- 1
Step 1: (5 min) Define the problem. As a group, clearly articulate the problem statement and write it visibly for all participants.
- 2
Step 2: (2 min) Distribute sticky notes. Give each participant five sticky notes, numbered 1 through 5.
- 3
Step 3: (10 min) Individual 'Why' generation. Instruct participants to individually write down their answer to 'Why is this a problem?' on sticky note #1. Then, for each subsequent sticky note, they should answer 'Why is the previous answer true?'
- 4
Step 4: (10 min) Share and synthesize. Have each participant post their sticky notes in columns under the 'Why?' headings. Facilitate a discussion to identify common themes and differences.
- 5
Step 5: (10 min) Refine the problem statement. As a group, use the insights gained to rewrite the problem statement, focusing on the root cause.
- Encourage honesty and open communication. Remind participants that the goal is to uncover the truth, not to assign blame.
- Prompt participants to consider different perspectives and avoid jumping to conclusions.
- Use a fishbone diagram to visually represent the 'Whys' and their relationships.
- Continue asking 'Why?' beyond five iterations if necessary to reach a meaningful root cause.
