“Statistics is the science of gaining information from numerical data.” -- Moore Definitions of Statistics Statistics: “the science of data involving collecting, classifying, summarizing, organizing, analyzing, and interpreting numerical information” -- McClave, Dietrich, Sincich

An understanding of variation An awareness of when and how variability affects quality An ability to identify variability that can be controlled A commitment to controlling and reducing variability in a never-ending striving for quality improvement Definition of Statistical Thinking -- Levine, Ramsey, Berenson

TQM Total Quality ManagementTotal Quality Management refers to a journey to excellence in which everyone in the organization is focused on continuous process improvement directed toward increased customer satisfaction.

Deming’s 14 Points 1. Create a constancy of purpose toward the improvement of products and services in order to become competitive, stay in business, and provide jobs. 2. Adopt the new philosophy. Management must learn that it is a new economic age and awaken to the challenge, learn their responsibilities, and take on leadership for change. 3. Stop depending on inspection to achieve quality. Build in quality from the start. 4. Stop awarding contracts on the basis of low bids. 5. Improve continuously and forever the system of production and service to improve quality and productivity, and thus constantly reduce costs.

Deming’s 14 Points 6. Institute training on the job. 7. Institute leadership. The purpose of leadership should be to help people and technology work better. 8. Drive out fear so that everyone may work effectively. 9. Break down barriers between departments so that people can work as a team. 10. Eliminate slogans, exhortations, and targets for the workforce. They create adversarial relationships. 11. Eliminate quotas and management by objectives. Substitute leadership. 12. Remove barriers that rob employees of their pride of workmanship.
