Exploring Deming’s System of Profound Knowledge for Effective Management

Deming's Profound Knowledge System in Management Leadership and Management

A key part of Deming’s System of Profound Knowledge (SoPK) is understanding variation. This includes knowing what constitutes normal and special causes of defects.

Understanding this enables you to avoid common mistakes that result in suboptimal results and rob workers of pride in workmanship. It also helps you to remove fear and competition from the workplace.

Deming’s Insights: The Four Pillars of Profound Knowledge

Edwards Deming is known as one of the world’s leading proponents of management philosophy. His theories are widely used in manufacturing in Japan and have been credited with helping that country become a global economic power. His work is also influencing many American companies who are incorporating his ideas into their quality management programs. He developed a four part system for managing that he called the System of Profound Knowledge. It includes the concepts of aiming, understanding variation, theory of knowledge and psychology.


Deming stressed that every company, project and individual are part of a bigger system. All of these parts need to be working together in order to get the best results. He also believed that the system should have a clearly defined aim that encompasses the future and is communicated to all of the employees.

Understanding Variation

The next pillar of profound knowledge is to understand that everything is subject to change. The best way to manage this is through a process of experimentation. This is often referred to as the PDSA cycle, which was coined by Walter Shewhart, the father of statistical process control. The cycle involves planning a change, doing it, studying the results and acting accordingly.

Theory of Knowledge

The final pillar of profound knowledge is to have a sound understanding of the system in which you operate. This can help you to identify the underlying assumptions that are driving decisions. This is especially important when it comes to evaluating change ideas because, as we all know, people have lots of theories about how things should be done. Understanding these theories can help to prevent them from derailing a worthy improvement effort.

Understanding Systems: A Key Component of Deming’s Philosophy

A key component of Deming’s philosophy is his concept that a system can be improved by changing how a business operates, not by focusing on specific individuals. This is a framework that can pull the focus away from blame and the concept of special causes and instead promotes understanding and building systems that work for everybody involved.

In addition, he emphasizes training for the purpose of quality improvement. He doesn’t want all of the knowledge of a process to be in one person’s head, and he encourages managers to share their own expertise with staff. This can help people understand how their work fits into the bigger picture, which can help them get more satisfaction from their jobs.

He also warns against tampering with processes, as this can lead to unintended consequences and may not produce the desired results. For example, if a manager tries to eliminate all of the variation in a process by taking out one variable at a time, it is not likely to be successful. Instead, he or she should try to improve the process by using control charts and analyzing the data before making changes.

Other aspects of his philosophy include a constant purpose for improving product and service, an end to reliance on inspection and the removal of barriers that rob workers of pride in their work. These can include slogans and exhortations, numerical quotas for employees and management, and annual rating or merit systems. This approach to management is in direct contrast to much of what is
being taught and practiced today, especially by many leadership and management consultants. But Deming’s teachings have withstood the test of time, and he believes that they can be used to change the world in a positive way.

Variation in Processes: Analyzing and Managing Change

As we continue on our journey through this series of posts, we will explore Deming’s System of Profound Knowledge (SoPK). This is a management theory that consists of four interconnected areas of understanding: appreciation for the system, knowledge of variation, theory of knowledge and psychology. Taking on these concepts can transform the way leaders think about their systems.

Rather than seeing their systems as a series of unrelated activities, managers can learn to view them as a network of intentional and unintentional causes and effects. This allows them to understand how changes in one area can impact other parts of the organization and lead to effective decision-making. It also emphasizes the importance of cooperation and breaking down barriers between departments.

Part of this understanding involves recognizing that all processes vary. Managers can distinguish between common cause variations, which are inherent in the process and can be reduced through improvements, and special cause variation, which is unique to a specific event and requires a different approach to managing it. In addition, leaders need to know how to measure the variability in their processes to make accurate decisions about how to improve them.

Finally, managers need a good theory of how to learn from their experience. They need to understand that they can acquire new knowledge by making a rational prediction and then revising the theory based on actual experience. By establishing this learning cycle, they can continually improve the system and move toward sustainable success. Without a theory of how to learn, managers will be forever stuck in the same place. This is why the theory of profound knowledge is so important for leaders to understand.

Theory of Knowledge: Deming’s Approach to Learning and Improvement

The Deming management method or System of Profound Knowledge as he called it, encourages people to work together. He believed that all components of a business must be integrated and that a leader should encourage and support the growth of employees as a whole. This is in direct contrast to many other theories of business management which use motivational techniques such as reward, punishment, or fear to control workers.

The principles of the Deming management method are focused on thinking together, learning together, working together and improving together. He also emphasized the importance of removing fear from the workplace. Fear is a huge deterrent to collaboration and innovation. This is a critical step in achieving continuous improvement.

Deming was a statistician and a quality consultant, so it is no surprise that he was focused on the importance of documentation in an improvement process. He encouraged leaders to document their efforts and experiment with various methods of improving a process. He also suggested that all experiments should be conducted using scientific methodology and a control group so that the results could be analyzed.

Finally, Deming encouraged the development of a theory to guide an organization’s actions. This should be a “living” theory which evolves as new discoveries are made. He believed that a good theory should allow a company to predict and anticipate problems and their causes.

While he never used the term Total Quality Management, or TQM, Deming’s management philosophy became associated with it early on. He did, however, advocate for the Plan-Do-Check-Act (PDCA) cycle.

The Role of Psychology in Deming’s Management Theory

The System of Profound Knowledge combines elements of appreciation for a system, understanding variation, theory of knowledge, and psychology into a holistic philosophy for transforming management style. A framework rooted in this philosophy encourages collaboration, continuous improvement, and a focus on quality – a combination that can lead any organization toward sustainable success.

One of the most influential industrialists of his time, William Edwards Deming was an engineer, statistician, professor, author, lecturer and management consultant. His work helped transform the Japanese economy after World War II, and he is widely considered to be responsible for bringing Japan into the modern age. He is best known for his 14 points for management and for presenting the principles that are the foundation of a total quality movement in business.

Deming’s philosophies were based on the belief that an organization can improve only if its managers change their approach to management, from one that is primarily focused on quarterly profits and the quarterly dividend, to one that promotes learning, innovation and long-term sustainability. He encouraged leaders to make a commitment to the future of their company by developing innovative plans that would protect investments, ensure future dividends and provide jobs.

In addition, leaders must understand that all people are different and that a person’s performance is largely governed by the system in which they operate. Leaders who understand this concept will avoid the tendency to reward people in ways that are counterproductive – such as by using slogans, annual reviews, merit ratings and quotas – and instead embrace leadership strategies that support growth, pride in workmanship and mutual cooperation. They will also recognize that a lack of understanding of psychology can cause misunderstandings and miscommunication and support the use of communication methods that will minimize such issues.
