basis against which change is measured.
✔✔batch and queue - ✔✔Producing more than one piece and then moving the pieces
to the next operation before they are needed.
✔✔Bayes's theorem - ✔✔A formula to calculate conditional probabilities by relating the
conditional and marginal probability distributions of random variables.
,✔✔benchmarking - ✔✔A technique in which a company measures its performance
against that of best-in-class companies, determines how those companies achieved
their performance levels, and uses the information to improve its own performance.
Subjects that can be benchmarked include strategies, operations, and processes.
✔✔benefit-cost analysis - ✔✔An examination of the relationship between the monetary
cost of implementing an improvement and the monetary value of the benefits achieved
by the improvement, both within the same time period. 562 Glossary
✔✔bias - ✔✔The influence in a sample of a factor that causes the data population or
process being sampled to appear different from what it actually is, typically in a specific
direction.3
✔✔binomial distribution - ✔✔A discrete distribution that is applicable whenever an
experiment consists of n independent Bernoulli trials and the probability of an outcome,
say, success, is constant throughout the experiment.1
✔✔Black Belt (BB) - ✔✔Full-time team leader responsible for implementing process
improvement projects; define, measure, analyze, improve, and control (DMAIC) or
define, measure, analyze, design, and verify (DMADV)—within a business to drive up
customer satisfaction and productivity levels.
✔✔block diagram - ✔✔A diagram that shows the operation, interrelationships, and
interdependencies of components in a system. Boxes, or blocks (hence the name),
represent the components; connecting lines between the blocks represent interfaces.
There are two types of block diagrams: a functional block diagram, which shows a
system's subsystems and lower-level products and their interrelationships and which
interfaces with other systems; and a reliability block diagram, which is similar to the
functional block diagram but is modified to emphasize those aspects influencing
reliability.
✔✔brainstorming - ✔✔A technique teams use to generate ideas on a particular subject.
Each person on the team is asked to think creatively and write down as many ideas as
possible. The ideas are not discussed or reviewed until after the brainstorming session.
Affinity diagrams and interelationship digraphs would benefit most from brainstorming.
✔✔breakthrough improvement - ✔✔A dynamic, decisive movement to a new, higher
level of performance.
✔✔business process reengineering (BPR) - ✔✔The concentration on improving
business processes to deliver outputs that will achieve results meeting the firm's
objectives, priorities, and mission.
✔✔calibration - ✔✔The comparison of a measurement instrument or system of
unverified accuracy to a measurement instrument or system of known accuracy to
,detect any variation from the required performance specification. Purpose: Stability of
measurement instrument
Purpose of the measurement instrument
How the environment interacts with the measurement instrument
✔✔capability - ✔✔The total range of inherent variation in a stable process determined
by using data from control charts.
✔✔causation - ✔✔The relationship between two variables. The changes in variable x
cause changes in y. For example, a change in outdoor temperature causes changes in
natural gas consumption for heating. If we can change x, we can bring about a change
in y.
✔✔cause - ✔✔An identified reason for the presence of a defect, problem, or effect.
✔✔cause-and-effect diagram - ✔✔A tool for analyzing process dispersion. It is also
referred to as the "Ishikawa diagram," because Kaoru Ishikawa developed it, Glossary
563 and the "fishbone diagram," because the completed diagram resembles a fish
skeleton. The diagram illustrates the main causes and subcauses leading to an effect
(symptom). The cause-and-effect diagram is one of the "seven tools of quality."
✔✔c-chart - ✔✔See count chart.
✔✔centerline - ✔✔A line on a graph that represents the overall average (mean)
operating level of the process.
✔✔central limit theorem - ✔✔A theorem that states that irrespective of the shape of the
distribution of a population, the distribution of sample means is approximately normal
when the sample size is large. 30 samples are considered efficient.
✔✔central tendency - ✔✔The tendency of data gathered from a process to cluster
toward a middle value somewhere between the high and low values of measurement.
✔✔certification - ✔✔The result of a person meeting the established criteria set by a
certificate granting organization.
✔✔Certified Six Sigma Black Belt (CSSBB) - ✔✔An ASQ certification.
✔✔Certified Six Sigma Green Belt (CSSGB) - ✔✔An ASQ certification.
✔✔chain reaction - ✔✔A chain of events described by W. Edwards Deming: improve
quality, decrease costs, improve productivity, increase market share with better quality
and lower price, stay in business, provide jobs, and provide more jobs.
, ✔✔chain sampling plan - ✔✔In acceptance sampling, a plan in which the criteria for
acceptance and rejection apply to the cumulative sampling results for the current lot and
one or more immediately preceding lots.
✔✔champion - ✔✔A business leader or senior manager who ensures that resources
are available for training and projects, and who is involved in periodic project reviews;
also an executive who supports and addresses Six Sigma organizational issues.
✔✔change agent - ✔✔An individual from within or outside an organization who
facilitates change in the organization; might be the initiator of the change effort, but not
necessarily.
✔✔changeover - ✔✔A process in which a production device is assigned to perform a
different operation or a machine is set up to make a different part—for example, a new
plastic resin and new mold in an injection molding machine. Changeover time consists
of the total time taken from last good piece to first good piece after changeover.
Analyzes and determines External and internal activities.
Internal setup is converted to external setup.
✔✔changeover time - ✔✔The time required to modify a system or workstation, usually
including both teardown time for the existing condition and setup time for the new
condition.
✔✔characteristic - ✔✔The factors, elements, or measures that define and differentiate a
process, function, product, service, or other entity.
✔✔chart - ✔✔A tool for organizing, summarizing, and depicting data in graphic form.
564 Glossary
✔✔charter - ✔✔A written commitment approved by management stating the scope of
authority for an improvement project or team.
✔✔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
