Quality Function Deployment (QFD): An iterative process used
to identify and define customer requirements and their effects on the design
Rapid Prototyping: A process for quickly transforming a
design into a three-dimensional, physical model.
Risk Management Tools: Tools used to
identify, assess, and mitigate the risks associated with product
Root Cause Analysis (RCA): A technique used to identify and
eliminate the sources of failures and problems.
Sigma: The Greek letter used to denote the standard
deviation of the normal distribution. The standard deviation is a measure of the
dispersion of the data.
Six Sigma: A quality approach used to obtain zero defects in
Statistical Process Control (SPC): The use of statistical
tools and techniques to identify, analyze, and control variation in
Statistical Quality Control (SQC): The use of statistical
methods to analyze, monitor, and control the quality of the product and the
Systems Requirement Review (SRR): A Systems Requirement
Review is conducted to ascertain progress in defining system technical
requirements. It helps users determine the direction and progress of the systems
engineering effort and the degree of convergence upon a balanced and complete
configuration. A Systems Requirement Review with the customer focuses
identification of and concurrence on the systems requirements and specifications
to ensure they are clear, concise, accurate, and verifiable.
Tolerance Analysis: Tolerance analysis is a study of the
deviation from nominal specifications that a component may have and still
satisfy quality requirements.
Trade Study or Tradeoff Analysis: A formal
decision-making method that can be used to solve many complex problems. Used in
producibility to rank potential design solutions against the product goals to
highlight the manufacturing advantages and disadvantages of each design
