1. Who Was W. Edwards Deming?
- Background: Born in Sioux City, Iowa, Deming earned degrees in electrical engineering and mathematical physics.
- Career Path: Worked at Western Electric and the U.S. Census Bureau, where he applied statistical methods to process improvement.
- Legacy: Credited with helping Japan rebuild its economy after WWII, Deming’s teachings led to a quality revolution in the country, paving the way for the creation of the Deming Prize for quality excellence and inspiring a new era of global industry standards.
2. Deming’s Core Philosophy
Deming believed that quality is a management responsibility, not just a technical function. His approach emphasized:
- Systems Thinking: Organizations are interdependent systems; optimizing parts without considering the whole creates waste.
- Variation Management: Most quality problems stem from system variation, not worker error.
- Continuous Improvement: Quality is a never-ending journey, not a one-time project. This principle should inspire us all to strive for excellence in our work continually, reinforcing the importance of ongoing improvement in achieving quality.
3. The 14 Points for Management
Deming’s 14 Points serve as a blueprint for organizational transformation:
- Create constancy of purpose toward improvement.
- Adopt a new philosophy of quality.
- Cease dependence on inspection to achieve quality.
- End awarding business on price alone.
- Improve constantly and forever.
- Institute training on the job.
- Adopt leadership, not supervision.
- Drive out fear.
- Break down barriers between departments.
- Eliminate slogans and targets for the workforce.
- Eliminate quotas and numerical goals.
- Remove barriers to pride in artistry.
- Institute education and self-improvement.
- Put everyone to work on the transformation.
4. The Check-Act (PDCA) cycle:
Deming popularized the Plan-Do-Check-Act (PDCA) cycle:
- Plan: Identify a problem and develop a hypothesis.
- Do: Implement a small-scale test.
- Check: Analyze results.
- Act: Standardize successful changes or adjust and repeat.
This iterative loop became the foundation for continuous improvement in Lean and Six Sigma.
5. Impact on Japan
- In 1950, Deming lectured Japanese engineers and executives on the principles of statistical quality control.
- His teachings helped companies like Toyota and Sony achieve world-class quality.
- Japan’s Deming Prize honors organizations that excel in quality management.
6. Deming vs. Juran
- Deming: Emphasized systems thinking, leadership, and statistical control.
- Juran: Focused on management responsibility and the Pareto Principle.
- Both agreed that quality improvement is a strategic, not just operational, endeavor.
7. Modern Relevance
Deming’s principles underpin:
- Lean Manufacturing
- Six Sigma
- Total Quality Management (TQM)
- Agile and Continuous Improvement frameworks
Key Takeaways
- Quality is built into processes, not inspected in.
- Leadership drives systemic change.
- Continuous improvement is essential for competitiveness.
