Question What are the common elements we can identify among
a) Baldridge criteria
b) Deming, Juran and Crosby
Answer Shewhart and Deming relied on the use of Control Charts (Shewhart in the 1920's and Deming in the 40'S). Shewhart created the basis for the control chart and the concept of a state of statistical control by carefully designed experiments. While Dr. Shewhart drew from pure mathematical statistical theories, he understood that data from physical processes seldom produces a "normal distribution curve". He discovered that observed variation in manufacturing data did not always behave the same way as data in nature. Shewhart concluded that while every process displays variation, some processes display controlled variation that is natural to the process (common causes of variation), while others display uncontrolled variation that is not present in the process causal system at all times (special causes of variation).
The philosophy of W. Edwards Deming has been summarized as follows:
"Dr. W. Edwards Deming taught that by adopting appropriate principles of management, organizations can increase quality and simultaneously reduce costs (by reducing waste, rework, staff attrition and litigation while increasing customer loyalty). The key is to practice continual improvement and think of manufacturing as a system, not as bits and pieces."
In the 1970s, Dr. Deming's philosophy was summarized by some of his Japanese proponents with the following 'a'-versus-'b' comparison:
(a) When people and organizations focus primarily on quality, defined by the following ratio,
quality tends to increase and costs fall over time.
(b) However, when people and organizations focus primarily on costs, costs tend to rise and quality declines over time.
The Deming System of Profound Knowledge
"The prevailing style of management must undergo transformation. A system cannot understand itself. The transformation requires a view from outside. The aim of this chapter is to provide an outside view—a lens—that I call a system of profound knowledge. It provides a map of theory by which to understand the organizations that we work in.
"The first step is transformation of the individual. This transformation is discontinuous. It comes from understanding of the system of profound knowledge. The individual, transformed, will perceive new meaning to his life, to events, to numbers, to interactions between people.
"Once the individual understands the system of profound knowledge, he will apply its principles in every kind of relationship with other people. He will have a basis for judgment of his own decisions and for transformation of the organizations that he belongs to. The individual, once transformed, will:
• Set an example;
• Be a good listener, but will not compromise;
• Continually teach other people; and
• Help people to pull away from their current practices and beliefs and move into the new philosophy without a feeling of guilt about the past."
Deming advocated that all managers need to have what he called a System of Profound Knowledge, consisting of four parts:
1. Appreciation of a system: understanding the overall processes involving suppliers, producers, and customers (or recipients) of goods and services (explained below);
2. Knowledge of variation: the range and causes of variation in quality, and use of statistical sampling in measurements;
3. Theory of knowledge: the concepts explaining knowledge and the limits of what can be known (see also: epistemology);
4. Knowledge of psychology: concepts of human nature.
Deming explained, "One need not be eminent in any part nor in all four parts in order to understand it and to apply it. The 14 points for management in industry, education, and government follow naturally as application of this outside knowledge, for transformation from the present style of Western management to one of optimization."
"The various segments of the system of profound knowledge proposed here cannot be separated. They interact with each other. Thus, knowledge of psychology is incomplete without knowledge of variation.
"A manager of people needs to understand that all people are different. This is not ranking people. He needs to understand that the performance of anyone is governed largely by the system that he works in, the responsibility of management. A psychologist that possesses even a crude understanding of variation as will be learned in the experiment with the Red Beads (Ch. 7) could no longer participate in refinement of a plan for ranking people."
The Appreciation of a system involves understanding how interactions (i.e. feedback) between the elements of a system can result in internal restrictions that force the system to behave as a single organism that automatically seeks a steady state. It is this steady state that determines the output of the system rather than the individual elements. Thus it is the structure of the organization rather than the employees, alone, which holds the key to improving the quality of output.
The Knowledge of variation involves understanding that everything measured consists of both "normal" variation due to the flexibility of the system and of "special causes" that create defects. Quality involves recognizing the difference in order to eliminate "special causes" while controlling normal variation. Deming taught that making changes in response to "normal" variation would only make the system perform worse. Understanding variation includes the mathematical certainty that variation will normally occur within six standard deviations of the mean.
The System of Profound Knowledge is the basis for application of Deming's famous 14 Points for Management, described below.
Deming's 14 points
Deming offered fourteen key principles for management for transforming business effectiveness. The points were first presented in his book Out of the Crisis.
1. Create constancy of purpose toward improvement of product and service, with the aim to become competitive and stay in business, and to provide jobs.
2. Adopt the new philosophy. We are in a new economic age. Western management must awaken to the challenge, must learn their responsibilities, and take on leadership for change.
3. Cease dependence on inspection to achieve quality. Eliminate the need for inspection on a mass basis by building quality into the product in the first place.
4. End the practice of awarding business on the basis of price tag. Instead, minimize total cost. Move towards a single supplier for any one item, on a long-term relationship of loyalty and trust.
5. Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease cost.
6. Institute training on the job.
7. Institute leadership (see Point 12 and Ch. 8 of "Out of the Crisis"). The aim of supervision should be to help people and machines and gadgets to do a better job. Supervision of management is in need of overhaul, as well as supervision of production workers.
8. Drive out fear, so that everyone may work effectively for the company. (See Ch. 3 of "Out of the Crisis")
9. Break down barriers between departments. People in research, design, sales, and production must work as a team, to foresee problems of production and in use that may be encountered with the product or service.
10. Eliminate slogans, exhortations, and targets for the work force asking for zero defects and new levels of productivity. Such exhortations only create adversarial relationships, as the bulk of the causes of low quality and low productivity belong to the system and thus lie beyond the power of the work force.
11. a. Eliminate work standards (quotas) on the factory floor. Substitute leadership.
b. Eliminate management by objective. Eliminate management by numbers, numerical goals. Substitute workmanship.
12. a. Remove barriers that rob the hourly worker of his right to pride of workmanship. The responsibility of supervisors must be changed from sheer numbers to quality.
b. Remove barriers that rob people in management and in engineering of their right to pride of workmanship. This means, inter alia, abolishment of the annual or merit rating and of management by objective (See Ch. 3 of "Out of the Crisis").
13. Institute a vigorous program of education and self-improvement.
14. Put everyone in the company to work to accomplish the transformation. The transformation is everyone's work. "Massive training is required to instill the courage to break with tradition. Every activity and every job is a part of the process."
Seven Deadly Diseases
The Seven Deadly Diseases (also known as the "Seven Wastes"):
1. Lack of constancy of purpose.
2. Emphasis on short-term profits.
3. Evaluation by performance, merit rating, or annual review of performance.
4. Mobility of management.
5. Running a company on visible figures alone.
6. Excessive medical costs.
7. Excessive costs of warranty, fueled by lawyers who work for contingency fees.
A Lesser Category of Obstacles:
1. Neglecting long-range planning.
2. Relying on technology to solve problems.
3. Seeking examples to follow rather than developing solutions.
4. Excuses, such as "Our problems are different."
When Joseph Juran began his career in the 1920s the principal focus in quality management was on the quality of the end, or finished, product. The tools used were from the Bell system of acceptance sampling, inspection plans, and control charts. The ideas of Frederick Winslow Taylor dominated.
Juran is widely credited for adding the human dimension to quality management. He pushed for the education and training of managers. For Juran, human relations problems were the ones to isolate. Resistance to change—or, in his terms, cultural resistance—was the root cause of quality issues. Juran credits Margaret Mead's book Cultural Patterns and Technical Change for illuminating the core problem in reforming business quality. He wrote Managerial Breakthrough, which was published in 1964, outlining the issue.
Juran's vision of quality management extended well outside the walls of the factory to encompass non-manufacturing processes, especially those that might be thought of as service related. For example, in an interview published in 1997 he observed:
The key issues facing managers in sales are no different than those faced by managers in other disciplines. Sales managers say they face problems such as "It takes us too long...we need to reduce the error rate." They want to know, "How do customers perceive us?" These issues are no different than those facing managers trying to improve in other fields. The systematic approaches to improvement are identical. ... There should be no reason our familiar principles of quality and process engineering would not work in the sales process.
The original stated purposes of the Malcolm Baldridge award were to:
• promote quality awareness
• recognize quality achievements of the US companies
• publicize successful quality strategies
The current award criteria are stated to have three important roles in strengthening US competitiveness:
• To help improve organizational performance practices, capabilities and results
• To facilitate communication and sharing of the best practice information among US organizations of all types
• To serve as a working tool for understanding and managing performance and for guiding planning and opportunities for learning
The criteria are designed to help organizations use an aligned approach to organizational performance management that results in:
• Delivery of ever-improving value to customers, contributing to market success
• Improvement in overall organizational effectiveness and capabilities
• Organizational and personal learning
The seven categories of the criteria are:
1. Leadership
2. Strategic Planning
3. Customer & Market Focus
4. Measurement, Analysis and Knowledge Management
5. Workforce Focus
6. Process Management
7. Results
The common elements are Leadership drives a culture of quality, a culture of quality drives workforce focus, workforce focus drives measuring and analyzing quality data, analyzing quality data drives continuous improvement.
