ASQ GREEN BELT FINAL EXAM 2026 QUESTIONS AND
ANSWERS RATED A+
✔✔check sheet - ✔✔A simple data recording device. The check sheet is custom-
designed by the user, which allows him or her to readily interpret the results. The check
sheet is one of the "seven tools of quality."
✔✔checklist - ✔✔A tool for ensuring that all important steps or actions in an operation
have been taken. Checklists contain items important or relevant to an issue or situation.
Checklists are often confused with check sheets chi square distribution—Probability
distribution of sum of squares of n independent normal variables.1
✔✔classification of defects - ✔✔The listing of possible defects of a unit, classified
according to their seriousness. Note: Commonly used classifications: class A, class B,
class C, class D; or critical, major, minor, and incidental; or critical, major, and minor.
Definitions of these classifications require careful preparation and tailoring to the
product(s) being sampled to ensure accurate assignment of a defect to the proper
classification. A separate acceptance sampling plan is generally applied to each class of
defects.
✔✔common causes - ✔✔Causes of variation that are inherent in a process over time.
They affect every outcome of the process and everyone working in the process. (AKA
chance causes.) Also see special causes.
✔✔compliance - ✔✔The state of an organization that meets prescribed specifications,
contract terms, regulations, or standards.
✔✔conformance - ✔✔An affirmative indication or judgment that a product or service has
met the requirements of a relevant specification, contract, or regulation
✔✔conformity assessment - ✔✔All activities concerned with determining that relevant
requirements in standards or regulations are fulfilled, including sampling, testing,
inspection, certification, management system assessment and registration, accreditation
of the competence of those activities, and recognition of an accreditation program's
capability.
✔✔constraint - ✔✔Anything that limits a system from achieving higher performance or
throughput; also, the bottleneck that most severely limits the organization's ability to
achieve higher performance relative to its purpose or goal.
✔✔consumer - ✔✔The external customer to whom a product or service is ultimately
delivered; also called end user.
,✔✔continuous (variables) data - ✔✔Data that vary with discontinuity across an interval.
The values of continuous data are often represented by floating point numbers. In
sampling, continuous data are often referred to as variables data.3
✔✔continuous flow production - ✔✔A method in which items are produced and moved
from one processing step to the next, one piece at a time. Each process makes only the
one piece that the next process needs, and the transfer batch size is one. Also referred
to as one-piece flow and single-piece flow. Glossary 565
✔✔continuous improvement (CI) - ✔✔Sometimes called continual improvement. The
ongoing improvement of products, services, or processes through incremental and
breakthrough improvements.
✔✔continuous quality improvement (CQI) - ✔✔A philosophy and attitude for analyzing
capabilities and processes and improving them repeatedly to achieve customer
satisfaction.
✔✔continuous sampling plan - ✔✔In acceptance sampling, a plan, intended for
application to a continuous flow of individual units of product, that involves acceptance
and rejection on a unit-by-unit basis and employs alternate periods of 100 percent
inspection and sampling. The relative amount of 100 percent inspection depends on the
quality of submitted product. Continuous sampling plans usually require that each t
period of 100 percent inspection be continued until a specified number i of consecutively
inspected units is found clear of defects. Note: For single-level continuous sampling
plans, a single d sampling rate (for example, inspect one unit in five or one unit in 10) is
used during sampling. For multilevel continuous sampling plans, two or more sampling
rates can be used. The rate at any given time depends on the quality of submitted
product.
✔✔control chart - ✔✔A chart with upper and lower control limits on which values of
some statistical measure for a series of samples or subgroups are plotted. The chart
frequently shows a central line to help detect a trend of plotted values toward either
control limit.
✔✔control limits - ✔✔The natural boundaries of a process within specified confidence
levels, expressed as the upper control limit (UCL) and the lower control limit (LCL).
✔✔control plan (CP) - ✔✔Written description of the systems for controlling part and
process quality by addressing the key characteristics and engineering requirements. It
includes:
KPIV & KPOV.
LSL & USL.
Unit of measurement.
According to Forrest W. Breyfogle III, said consider at least 7 attributes when creating
,✔✔corrective action - ✔✔A solution meant to reduce or eliminate an identified problem.
✔✔corrective action recommendation (CAR) - ✔✔The full cycle corrective action tool
that offers ease and simplicity for employee involvement in the corrective action/process
improvement cycle.
✔✔correlation (statistical) - ✔✔A measure of the relationship between two data sets of
variables. the sign of the r value represents if r is positive, the slope of the line is
increasing.
✔✔cost of poor quality (COPQ) - ✔✔The costs associated with providing poor-quality
products or services. There are four categories: internal failure costs (costs associated
with defects found before the customer receives the product or service), external failure
costs (costs associated with defects found after the customer receives the product or
service), appraisal costs (costs incurred to determine the degree of conformance to
quality requirements), and prevention costs (costs incurred to keep failure and appraisal
costs to a minimum). 566 Glossary
✔✔cost of quality (COQ) - ✔✔Another term for COPQ. It is considered by some to be
synonymous with COPQ but is considered by others to be unique. While the two
concepts emphasize the same ideas, some disagree as to which concept came first and
which categories are included in each.
✔✔count chart - ✔✔A control chart for evaluating the stability of a process in terms of
the count of events of a given classification occurring in a sample; known as a "c-chart."
✔✔count per unit chart - ✔✔A control chart for evaluating the stability of a process in
terms of the average count of events of a given classification per unit occurring in a
sample.
✔✔Cp - ✔✔The ratio of tolerance to six sigma, or the upper specification limit (USL)
minus the lower specification limit (LSL) divided by six sigma. It is sometimes referred to
as the engineering tolerance divided by the natural tolerance and is only a measure of
dispersion. Best for random sampling of data.
✔✔Cpk index - ✔✔Equals the lesser of the USL minus the mean divided by three sigma
(or the mean) minus the LSL divided by three sigma. The greater the Cpk value, the
better.
✔✔Cpm - ✔✔Used when a target value within the specification limits is more significant
than overall centering.3
✔✔critical path method (CPM) - ✔✔An activity-oriented project management technique
that uses arrow-diagramming techniques to demonstrate both the time and the cost
required to complete a project. It provides one-time estimate: normal time. The earliest
, time represents the estimated time at which the event will occur if the preceding
activities are started as early as possibleThe latest time for an event is the estimated
time the event can occur without delaying the completion of the project beyond its
earliest time. Slack time for an event is the difference between the latest and earliest
times for a given event, hence incorrect. Budgeted time is not a component of critical
path.
✔✔critical to quality (CTQ) - ✔✔A characteristic of a product or service that is essential
to ensure customer satisfaction.2 cumulative sum control chart (CUSUM)—A control
chart on which the plotted value is the cumulative sum of deviations of successive
samples from a target value. The ordinate of each plotted point represents the algebraic
sum of the previous ordinate and the most recent deviations from the target.
✔✔customer relationship management (CRM) - ✔✔A strategy for learning more about
customers' needs and behaviors to develop stronger relationships with them. It brings
together information about customers, sales, marketing effectiveness, responsiveness,
and market trends. It helps businesses use technology and human resources to gain
insight into the behavior of customers and the value of those customers.
✔✔customer satisfaction - ✔✔The result of delivering a product or service that meets
customer requirements.
✔✔cycle time - ✔✔The time required to complete one cycle of an operation. If cycle
time for every operation in a complete process can be reduced to equal takt time,
products can be made in single-piece flow. Also see takt time.
✔✔cyclical variation - ✔✔Looks at the piece-to-piece changes in consecutive order.
Patterns are identified in groups, batches, or lots of units.3 Glossary 567
✔✔data - ✔✔A set of collected facts. There are two basic kinds of numerical data:
measured or variables data, such as "16 ounces," "4 miles," and "0.75 inches," and
counted or attributes data, such as "go/no go" or "yes/no."
✔✔data chart - ✔✔Matrix and prioritization are examples of data charts
✔✔decision matrix - ✔✔A matrix teams use to evaluate problems or possible solutions.
For example, a team might draw a matrix to evaluate possible solutions, listing them in
the far left vertical column. Next, the team selects criteria to rate the possible solutions,
writing them across the top row. Then, each possible solution is rated on a scale of 1 to
5 for each criterion, and the rating is recorded in the corresponding grid. Finally, the
ratings of all the criteria for each possible solution are added to determine its total score.
The total score is then used to help decide which solution deserves the most attention.
✔✔defect - ✔✔A product's or service's nonfulfillment of an intended requirement or
reasonable expectation for use, including safety considerations. There are four classes
