Gage repeatability and reproducibility (GR&R): The evaluation of a gauging instrument’s accuracy by determining whether its measurements are repeatable (there is close agreement among a number of consecutive measurements of the output for the same value of the input under the same operating conditions) and reproducible (there is close agreement among repeated measurements of the output for the same value of input made under the same operating conditions over a period of time).
Gain sharing: A reward system that shares the monetary results of productivity gains among owners and employees.
Gantt chart: A matrix-type horizontal bar chart used in process/project planning and control to display planned and finished work in relation to time. It is called a milestone chart when interim checkpoints are added.
Gap analysis: The comparison of a current condition to the desired state.
Gatekeeper: A timekeeper; in team meetings, a designated individual who helps monitor the team’s use of allocated time.
Geometric dimensioning and tolerancing (GD&T): A set of rules and standard symbols to define part features and relationships on an engineering drawing depicting the geometric relationship of part features and allowing the maximum tolerance that permits full function of the product.
George M. Low Trophy: An award presented by NASA to NASA aerospace industry contractors, subcontractors and suppliers that consistently maintain and improve the quality of their products and services. George M. Low was the NASA administrator for nearly three decades.
New! Global quality: The systematic design and implementation of quality processes across the world, based on information-sharing and best practices.
Goal: A broad statement describing a desired future condition or achievement without being specific about how much and when.
Go/no-go: State of a unit or product. Two parameters are possible: go (conforms to specifications) and no-go (does not conform to specifications).
Good laboratory practices (GLP): A quality system (for example, 21 CFR, part 58) for labs and organizations to use to ensure the uniformity, consistency, reliability, reproducibility, quality and integrity of testing performed. Promoted by the Organization for Economic Co-operation and Development (OECD) and some regulatory agencies in the world.
Good manufacturing practices (GMP): A minimum set of practices recommended or required by some regulatory agencies (for example, 21 CFR, parts 808, 812 and 820) for manufacturers to meet to ensure their products consistently meet requirements for their intended use.
Green Belt (GB): An employee who has been trained in the Six Sigma improvement method and can lead a process improvement or quality improvement team as part of his or her full-time job.
Group dynamic: The interaction (behavior) of individuals within a team meeting.
Groupthink: A situation in which critical information is withheld from the team because individual members censor or restrain themselves, either because they believe their concerns are not worth discussing or because they are afraid of confrontation. Occurs when most or all team members coalesce in supporting an idea or decision that hasn’t been fully explored.
