◉ continuous improvement (CI). Answer: Sometimes called
continual improvement. The ongoing improvement of products,
services, or processes through incremental and breakthrough
improvements.
◉ continuous quality improvement (CQI). Answer: A philosophy and
attitude for analyzing capabilities and processes and improving
them repeatedly to achieve customer satisfaction.
◉ continuous sampling plan. Answer: 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. Answer: 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. Answer: 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). Answer: 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. Answer: A solution meant to reduce or eliminate
an identified problem.
◉ corrective action recommendation (CAR). Answer: The full cycle
corrective action tool that offers ease and simplicity for employee
involvement in the corrective action/process improvement cycle.
,◉ correlation (statistical). Answer: 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). Answer: 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). Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer: 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. Answer: Used when a target value within the specification
limits is more significant than overall centering.3
◉ critical path method (CPM). Answer: 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.
