Quality Terminology Flashcards
Upper Specification Limit
Is the maximum value used to determine if a process is within specification.
Upper Control Limit
Is the maximum value used to determine if a process is within control.
Lower Control Limit
Is the minimum value used to determine if -a process is within control.
Lower Specification Limit
Is the minimum value used to determine if a process is within specification .
Mean
The average value in a measurement of a population
Rolled throughput yield (RTY)
Is the probability or likelihood, measured in percentage, of a unit going through a process with no defects.
Benchmarking
The comparison of a current product to industry standards or past standards to attain a measurement or baseline
Brainstorming
A data-generating technique which includes team members or subject matter experts for the purpose of solving project problems, identifying project risk , and planning-related activities
Common Cause
A predictable source of variation in a system
Conformance
Creation and delivery of a product that has met the specified requirements and conformance (or functionality) of use
Conformance to Requirement
The point where the project and product meet the standards of the written specifications defined at project inception (or modified through change control)
Control Chart
A graph of data that shows the measurement of a process over elapsed time
Control Limits
The area of measurement three standard deviations (or Sigma) from the mean on a control chart
Corrective Action
Action taken to bring project in line with the project management plan
Cost of Nonconformance
Cost associated with not meeting quality expectations of the project or product
Cost of Quality (COQ) (Technique)
Cost of conformance to requirements and non-conformance
Defect
A problem or error in the creation of the work of the project
Defect Repair
The process of correcting or improving an error in the creation of the project
Design of Experiments (DOE)
A process that examines which variables have the greatest outcome on a process or product
Failure Mode and Effect Analysis (FMEA)
A process that analyzes every failure mode in every piece of a product- The analysis is then reviewed for impact on every aspect of the system.
Features
The characteristics that the user desires built into a product
Fishbone Diagrams (Ishikawa Diagrams)
Diagrams that break down possible areas for failure in a process and allow analysis of impact for the area; sometimes considered an ideal tool for root cause analysis
Fitness for Use
A product that can be used as it was intended when designed
Flowcharting (Technique)
A decomposition approach to breaking a system or process into block steps that can be repeated by following the diagram
