Study Notes
Walter Shewhart and Genichi Taguchi's Life Works and Contributions to Quality Control and Assurance
- Walter Shewhart is considered the "Father of Statistical Quality Control" with a Bachelor's and Master's degree in Electrical Engineering and a Doctorate in Physics.
- He worked at Western Electric Company (1918-1924) and Bell Telephone Laboratories (1925-1956).
- Shewhart developed Statistical Process Control (SPC) and introduced the concept of Control Charts.
Statistical Process Control (SPC)
- SPC is the use of statistical techniques to control a process or production method.
- SPC tools and procedures help monitor process behavior, discover issues in internal systems, and find solutions for production issues.
The Concept of Control Charts
- A control chart is a graph used to study how a process changes over time.
- A control chart has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit.
The Shewhart Cycle (Plan-Do-Study-Act)
- The PDCA/PDSA cycle is a continuous loop of planning, doing, checking (or studying), and acting.
Six Sigma
- The Five Steps of Six Sigma: Define, Measure, Analyze, Improve, and Control.
- Examples of Six Sigma projects in multiple sectors include improving customer service, product design, quality control processes, and reducing lead times and defects.
Quality Standards
- Quality standards refer to sets of guidelines, systems, methods, requirements, and specifications followed by an organization to ensure consistent process and product quality.
- Quality standards are established by industry regulatory boards to drive customer satisfaction and maintain compliance.
Theoretical Contributions
- Theoretical contribution is a process based on theory development and advancement in existing theory with logic and facts.
- Theories act as a conceptual base for understanding and analyzing research, explaining phenomena, and providing simplified explanations of complexity in reality.
Walter Shewhart's Book: "Economic Control of Quality of Manufactured Product"
- Published in 1931, this book introduced statistical principles of industrial quality control.
- The book consists of 25 chapters divided into seven parts, and three appendices.
- Shewhart's method involves two types of situations: where the standard of quality is given in advance, and bringing a system into a state of maximum control.
Theory of Variability
- Variation theory explains how a learner might come to see, understand, or experience a given phenomenon in a specific way.
- The principles of variation theory include the limited capacity of working memory, numerous features that might consume attention, and established collective knowledge being well structured and reliant on specific….
Genichi Taguchi's Contributions
- Taguchi believed that making products consistently good while using fewer resources saves money (cost reduction).
- Taguchi's methods for efficiency improvement focus on optimizing manufacturing processes to achieve higher levels of productivity and performance.
- Taguchi's influence on manufacturing extends beyond Japan and has had a profound impact on global manufacturing practices.
