In this activity, students investigate the causes of a problem by repeatedly asking the question “Why?”. By doing this five times, they dig deeper and reveal the underlying factors that create or reinforce the problem. The method helps students move beyond surface-level problem definitions and identify where real interventions are needed.

Step-by-step
Step 1
Formulate the problem: Write down a clear problem statement you want to analyze.
Step 2
Ask the first ‘why’: Ask: Why do we have this problem? Write down the answers.
Step 3
Go deeper: For each answer, ask again: Why is this the case? Repeat the process five times or until no new insights appear.
Step 4
Visualize the layers: Write or draw the answers in layers, so that the chain of causes becomes visible.
Step 5:
Discuss insights: Discuss as a group which causes seem fundamental and which are just symptoms. What patterns emerge?
Step 6
Reflect: Have students consider: How does this insight change our understanding of the problem? and What direction for solutions becomes clearer?
Variation 1
Let groups present their ‘5 why’ chain to another group, who can challenge them to go deeper.
Variation 2
This method also works as an individual writing exercise, followed by a group discussion.
Tip 1
Encourage students not to settle for the first answer – the deeper insights often come later.
Tip 2
Keep the activity light and creative: sometimes an unexpected “why” brings the strongest insight.
Paper and markers or a digital visualization tool such as Miro to map the why-chain.
