- Appraisal Costs: Costs incurred to detect which of the individual units of products do not conform to specifications
- Average Waiting Time: The average amount of time that an order will wait in line before machine is set up and order is processed
- Bottleneck: An operation where the work to be performed approaches or exceeds the capacity available to do it
- Cause-and-Effect Diagram: Diagram that identifies potential causes of defects. Four categories of potential causes are: human factors, methods and design factors, machine-related factors, and materials and components factors
- Conformance Quality: Refers to the performance of a product or service relative to its design and product specifications
- Control Chart: Graph of a series of successive observations of a particular step, procedure, or operation taken at regular intervals of time. Each observation is plotted relative to specific ranges that represent the limits within which observations are expected to fall
- Costs of Quality (COQ): Costs incurred to prevent, or the costs arising as a result of, the production of a low-quality product
- Customer-Response Time: Duration from the time a customer places an order for a product or service to the time the product or service is delivered to the customer
- Design Quality: Refers to how closely the characteristics of a product or service meet the needs and wants of customers
- External Failure Costs: Costs incurred on defective products after they are shipped to customers
- Internal Failure Costs: Costs incurred on defective products before they are shipped to customers
- Manufacturing Cycle Time: Another term for manufacturing lead time
- Manufacturing Lead Time: Duration between the time an order is received by manufacturing to the time a finished good is produced
- On-time Performance: Delivering a product or service by the time it is scheduled to be delivered
- Pareto Diagram: Chart that indicates how frequently each type of defect occurs, ordered from the most frequent to the least frequent
- Prevention Costs: Costs incurred to preclude the production of products that do not conform to specifications
- Quality: The total features and characteristics of a product made or a service performed according to specifications to satisfy customers at the time of purchase and during use
- Theory of Constraints: Describes methods to maximize operating income when faced with some bottleneck and some non-bottleneck operations
- Throughput Contribution: Revenues minus the direct material cost of the goods sold
- Time Driver: Any factor in which a change in the factor causes a change in the speed of an activity
