W.E. Deming, a renowned statistician and quality control expert, revolutionized post-war Japanese manufacturing and is credited with laying the foundation for Total Quality Management (TQM). His assertion that “85% of poor quality can be attributed to management” is a powerful statement challenging the traditional focus on worker error. This perspective highlights the systemic nature of quality issues, arguing that management’s responsibility extends beyond simply inspecting for defects to designing a system that prevents them. In the context of World Class Manufacturing (WCM) systems, which aim for best-in-class performance across all operational facets, Deming’s philosophy is not merely relevant but foundational.
Deming’s Philosophy: A Systemic Approach
Deming’s philosophy revolves around the concept of a system of profound knowledge, comprising four interconnected elements: appreciation for a system, knowledge of variation, theory of knowledge, and psychology. He emphasized that organizations are systems, not merely collections of independent parts. Improvements in quality and productivity come from optimizing the system as a whole, not from blaming individuals. His famous 14 Points for Management provide a framework for transforming organizations, focusing on continuous improvement, eliminating fear, fostering collaboration, and investing in education and self-improvement.
Management’s Role in Quality: Beyond Inspection
Deming argued that focusing solely on identifying and correcting defects (inspection) is a reactive and ultimately ineffective approach. He believed that the vast majority of quality problems stem from flaws in the system itself, which are often created or perpetuated by management decisions. These flaws can manifest in several ways:
- Poor Process Design: Inefficient or poorly designed processes inherently lead to errors and defects.
- Lack of Training: Insufficient training and skill development leave employees unprepared to perform their tasks effectively.
- Unclear Expectations: Ambiguous goals and unclear performance standards create confusion and inconsistency.
- Inadequate Resources: Insufficient funding, equipment, or personnel hinder the ability to maintain quality standards.
- Short-Term Focus: Prioritizing short-term profits over long-term quality investments leads to cost-cutting measures that compromise quality.
- Lack of Data-Driven Decision Making: Decisions based on intuition rather than objective data analysis often result in suboptimal outcomes.
For example, if a machine is consistently producing defective parts, blaming the operator is a superficial solution. The root cause might be a poorly maintained machine, inadequate training on machine operation, or a flawed process design. Addressing these systemic issues requires management intervention.
World Class Manufacturing (WCM) & Deming’s Principles
World Class Manufacturing (WCM) is a philosophy and set of practices focused on eliminating waste and maximizing efficiency across all aspects of a manufacturing operation. Key elements of WCM – such as Lean Manufacturing, Six Sigma, Total Productive Maintenance (TPM), and Just-in-Time (JIT) – are deeply aligned with Deming’s principles.
| WCM Element | Deming Principle Alignment |
|---|---|
| Lean Manufacturing (Waste Reduction) | System Thinking – Identifying and eliminating waste is a systemic improvement. |
| Six Sigma (Defect Reduction) | Knowledge of Variation – Using statistical methods to understand and reduce process variation. |
| Total Productive Maintenance (TPM) | Continuous Improvement – Proactive maintenance prevents defects and improves equipment reliability. |
| Just-in-Time (JIT) | Process Control – Optimizing flow and reducing inventory requires tight process control. |
A WCM implementation *cannot* succeed without a management team committed to Deming’s principles. Management must create a culture of continuous improvement, empower employees, invest in training, and prioritize long-term quality over short-term gains. Without this commitment, WCM initiatives will likely falter, resulting in limited or unsustainable improvements.
The Toyota Production System (TPS), often considered the archetype of WCM, exemplifies Deming’s principles in action. Toyota’s emphasis on *kaizen* (continuous improvement), *genchi genbutsu* (going to the source to understand problems), and respect for people are all directly inspired by Deming’s teachings.
Conclusion
Deming’s assertion that 85% of poor quality stems from management remains profoundly relevant in the context of World Class Manufacturing. WCM is not simply a collection of tools and techniques; it is a holistic approach that requires a fundamental shift in management thinking. By embracing Deming’s principles of system thinking, continuous improvement, and employee empowerment, organizations can create a culture of quality that drives sustainable competitive advantage. The success of WCM hinges on management’s willingness to accept responsibility for quality and to invest in the systems and people that will deliver it.
