5 Whys Diagram: A Step-by-Step Guide with Real-Life Example

As product owners, UX researchers, and problem-solvers, we encounter challenges that demand more than surface-level fixes. When issues arise, it’s essential to dig deep and uncover the underlying causes. Enter the 5 Whys—a simple yet potent tool that peels away layers of complexity to reveal the core problems. In this article, we’ll explore the 5 Whys template, understand its significance, and illustrate its application with real-world examples.

What Is the 5 Whys Technique?

The 5 Whys is a structured approach used to identify the root cause of a problem by asking “why” repeatedly. By delving into the layers of causality, teams gain insights beyond symptoms and address issues at their source. Let’s break down the process:

Identify the Key Issue or Problem:

• Clearly define the problem you’re tackling. What’s the main issue affecting your process or outcome?
• Quantify or measure the problem to make it measurable.
• Consider the impact of the problem on your desired results.
• Determine when the problem started (time frame) and where it occurred (location).
• Identify the people or groups involved or affected by the problem.

Ask the First ‘Why?’:

• Why did the problem occur? Start the analysis process.
• Uncover the initial cause and validate it.

Ask the Second ‘Why?’:

• Dig deeper into the root cause. Why did the identified cause happen?
• Validate the second-level cause.

Ask the Third ‘Why?’:

• Continue tracing back. What secondary cause led to the initial issue?
• Validate the third-level cause.

Ask the Fourth ‘Why?’:

• Trace all the way to the root cause. Why did the secondary cause occur?
• Validate the fourth-level cause.

Ask the Fifth ‘Why?’ (If Necessary):

• Confirm and validate the ultimate cause, if identified.

Document Findings and Conclusions:

• Record the root cause and insights.
• Implement suitable corrective measures.
• Monitor the outcomes of your actions.

Why Should You Use the 5 Whys Template?

Identify Root Causes:

1. The 5 Whys method goes beyond symptoms, revealing the underlying issues.
2. It ensures effective solutions by targeting the source of the problem.

Improve Problem-Solving Skills:

1. Critical thinking thrives as you peel back layers systematically.
2. Informed decision-making leads to better outcomes.

Real-World Examples:

Website Downtime:

Issue: Frequent website crashes.

• 1st Why: Why does the website crash? (Server overload.)
• 2nd Why: Why is the server overloaded? (Insufficient capacity.)
• 3rd Why: Why is capacity insufficient? (Underestimated traffic.)
• 4th Why: Why was traffic underestimated? (Lack of historical data.)
• 5th Why: Confirm data deficiency and address it.

High Bounce Rates on a Landing Page:

Issue: Visitors leave immediately.

• 1st Why: Why do visitors bounce? (Slow page load.)
• 2nd Why: Why is the page slow? (Large image files.)
• 3rd Why: Why use large images? (No image optimization.)
• 4th Why: Why no optimization? (Lack of awareness.)
• 5th Why: Educate the team on image optimization.

Remember, the 5 Whys isn’t about blame—it’s about understanding and improvement. So, next time you face a challenge, ask “why” and unravel the hidden truths behind it! 🚀

Problem: Production line stopped.

Why?

Because a machine broke down.

Why?

Because it wasn't maintained properly.

Why?

Because the maintenance schedule wasn't followed.

Why?

Because there was no reminder system in place for maintenance.

Why?

Because the responsibility for scheduling maintenance wasn't clearly defined.
