What is Quality? QUALITYis the ability of a product or service to consistently meet or exceed customer expectations • Quality control is monitoring, testing, and correcting quality problems after they occur. • Quality assurance is providing confidence in a products quality by preventing defects before they occur.
Costs of Quality • Failure Costs - costs incurred by defective parts/products • Internal Failure Costs • Fixing problems during production • External Failure Costs • fixing problems after delivery to customer.
Costs of Quality (continued) Appraisal Costs • Inspection and testing Prevention Costs • Quality training, planning, customer assessment, creating standard operating procedures
The Quality Gurus • fitness-as-use • trilogy: planning, control & improvement • continuous improvement • cost of quality • 14 points • mgmt must fix system • reduce variation • SPC, PDSA • “total field” • quality at the source • zero defects • “Do it right the first time.” • Quality is free W. Edwards Deming Joseph M. Juran Armand Feigenbaum Philip B. Crosby 13
Quality Certification • ISO 9001 • Set of international standards on quality management and quality assurance, critical to international business • Standards Council of Canada • > 100 countries and 180 technical committees • Documentation and assessment process takes 12 – 18 months for certification • Re-register every 3 years

Hazard Analysis Critical Control Point (HACCP) • A quality control system, similar to ISO 9001, designed for food processors • Deals with food safety (biological, chemical, and physical hazards) • Main steps: • Hazard Analysis • Determination of the Critical Control Points • Creation of the HACCP Plan

Total Quality Management (TQM) A philosophy that involves everyone in an organization in a continual effort to improve quality and achieve customer satisfaction

Six Sigma • Statistically • Having no more than 3.4 defects per million • Conceptually • Program designed to reduce defects • Requires the use of certain tools and techniques Six sigma: A business process for improving quality, reducing costs, and increasing customer satisfaction.
