The Five Whys is a problem-solving technique that involves asking “why” five times to identify the root cause of a problem, intent or purpose.
When applied to a negative problem (e.g., “Why did the machine fail?”), the Five Whys uncovers a root cause—the fundamental defect or breakdown in the system.
However, when applied to a design system, a policy, or moral law (like the Ten Commandments), asking “why” repeatedly does not reveal a failure; it strips away surface-level mechanics to uncover the ultimate purpose, foundational intent, or target condition.
Why “Purpose” Functions as the “Root Cause”
In quality systems, Deming emphasized that every system must have an aim. Without an aim, you cannot evaluate whether a system is succeeding or drifting.
-
The Commandment is the Mechanism: “You shall not steal” is an operational boundary (a rule).
-
The “Why” uncovers the System Target: Asking “Why?” five times reveals that the boundary exists to protect mutual trust, justice, and social cooperation.
-
Purpose IS the System Root Cause: The root “cause” for the existence of the rule is its purpose—human flourishing and alignment with God’s design.
When you reach the top level—such as Loving God wholeheartedly and loving your neighbor as yourself (Matthew 22:37-40)—you have arrived at the ultimate aim of the system.
When applied to the Ten Commandments, it can help uncover the deeper principles behind each commandment rather than viewing them merely as rules.

Summary: The System Behind the Commandments
Viewed through a quality-management lens, the Ten Commandments form an interconnected system:
| Commandments |
Underlying Principle |
| 1–4 |
Right relationship with God |
| 5 |
Respect for authority and family |
| 6 |
Sanctity of life |
| 7 |
Faithfulness |
| 8 |
Justice and stewardship |
| 9 |
Truth and integrity |
| 10 |
Contentment and purity of heart |
Applying the Five Whys suggests that the commandments ultimately converge on a single systemic principle:
Love God wholeheartedly and love your neighbor as yourself.
This aligns with Jesus’ summary of the Law (Matthew 22:37-40), which can be viewed as the deepest “root cause” beneath all Ten Commandments. From a Deming or systems-thinking perspective, the commandments are not ten disconnected rules but components of a system designed to promote human flourishing, social stability, and alignment with God’s purposes.
This is where the framework becomes especially useful from a Deming, Taguchi, and systems-thinking perspective.
A principle often attributed to quality management is:
“You cannot manage what you do not measure.”
The Ten Commandments establish the target condition. The Taguchi Loss Function identifies the cost of deviation. The next step is to identify leading and lagging indicators that allow a community, church, county, state, or nation to monitor movement toward or away from the target.
The challenge is that many of the commandments involve moral and spiritual conditions that cannot be measured directly. Therefore, we measure the effects of deviation.
Taguchi Loss Function applied to the ten commandments to: (1) establish the target condition; identify the cost of deviation , identify leading and lagging indicators that allow a community, church, county, state, or nation to monitor movement toward or away from the target.
In Taguchi’s quality engineering, any variation or deviation from the ideal target creates an exponential loss (cost, friction, breakdown) to the broader system—even if the variation remains within traditionally “acceptable” bounds.
Here is the breakdown of the target conditions, costs of deviation, and leading/lagging indicators across the Ten Commandments framework for community and societal evaluation:
