Comprehensive vocabulary flashcards covering the principles, history, gurus, tools, and methodologies of Total Quality Management (TQM) and Operations Management.

Operations Management

The practice of handling day-to-day business functions in a manner that is efficient and maximizes profitability, focusing on formulating strategies and overseeing processes such as sourcing, staffing, production, and delivery.

Grade

Quality Inspection

The earliest stage of quality evolution (originating in the 1910s with the Ford Model T) focused on post-production sorting to separate acceptable items from defective ones.

Quality Control (QC)

The second evolution stage of quality, developed during World War II, relying on supervised skills, written specifications, measurement, standardization, and statistical quality control by inspection.

Quality Assurance (QA)

The third stage in quality evolution (originating around 1950) that incorporates previous stages to build customer confidence by shifting focus from defect detection toward defect prevention.

Total Quality Management (TQM)

An organization-wide philosophy and corporate culture characterized by increased customer satisfaction through continuous improvement, in which all employees across all levels and departments actively participate.

Dr. W. Edwards Deming's five-step product cycle introduced to Japanese industry in 1950: 1. Design the product, 2. Make and test it, 3. Put it on the market, 4. Test it in service through market research, and 5. Re-design based on consumer reactions.

Juran's Quality Trilogy

Dr. Joseph Juran's three-part managerial approach comprising Quality Planning (analogous to budgeting), Quality Control (analogous to cost control), and Quality Improvement (analogous to profit improvement).

Four Absolutes of Quality Management

Philip Crosby's four foundational rules: 1. Quality means conformance to requirements; 2. Quality comes from prevention, not appraisal; 3. The standard of performance is Zero Defects; 4. Quality measurement is the cost of nonconformance.

A statistical engineering system created by Dr. Genichi Taguchi emphasizing design-for-quality across three stages (System Design, Parameter Design, and Tolerance Design) to make products robust against variations.

Poka Yoke

A manufacturing concept developed by Shigeo Shingo meaning mistake-proofing, designed to immediately halt operations when a defect occurs to prevent root errors at the source.

SMED (Single Minute Exchange of Die)

A rapid tooling changeover method created by Shigeo Shingo that reduces setup times from hours down to single-digit minutes, facilitating small batch manufacturing.

Internal Customers
