Key points of Honda’s easy-to-use and effective why-why analysis and how to develop it

Understanding the Basics of Why-Why Analysis

Why-Why Analysis is a problem-solving method that aims to uncover the root cause of an issue by asking “why” multiple times.
This technique, popularized by Toyota, is now widely used across various industries.
Today, we will focus on Honda’s unique approach to Why-Why Analysis, which emphasizes usability and effectiveness.

The Core Principles

Honda’s Why-Why Analysis is built on a foundation of simplicity and depth.
The primary goal is to ensure that each “why” leads you closer to the root cause.
Rather than just scratching the surface, this method encourages an in-depth exploration of the issue at hand.

Step-by-Step Process

To perform a Why-Why Analysis, a team must follow several steps:

1. **Identify the Problem:** Clearly define what issue needs addressing.
It is crucial for everyone involved to have a shared understanding of the problem.

2. **Ask the First ‘Why’:** Begin by inquiring why the problem occurred.
The initial answer should provide insight into a primary cause.

3. **Ask ‘Why’ Repeatedly:** Continue asking “why” to the answer received from the previous step.
Each answer should bring the analysis closer to the root cause.

4. **Distinguish Causes:** Ensure that the reasons are distinct and don’t overlap.
This prevents confusion and ensures clarity in the analysis.

5. **Reach the Root Cause:** After a series of “whys,” the team should identify the root cause.
For most issues, five repetitions are sufficient, but the number can vary.

6. **Implement Solutions:** Once the root cause is identified, implement solutions to ensure the problem does not reoccur.
