  35. 35. Quality Definitions – Page 1 (Return to Index) Abilene paradox A paradox in which a group of people collectively decide on a course of action that is counter to the preferences of any of the individuals in the group. It involves a common breakdown of group communication in which each member mistakenly believes that their own preferences are counter to the group's, and therefore, does not raise objections. A common phrase relating to the Abilene paradox is "rocking the boat". Academic Quality Improvement Project (AQIP) A forum for higher education institutions to review one another’s action projects. Accelerated test Test in which the applied stress level is chosen to exceed that stated in the reference conditions in order to shorten the time required to observe the stress response of the item, or to magnify the response in a given duration. To be valid, an accelerated test must not alter the basic modes and/or mechanisms of failure. Acceptance quality limit In a continuing series of lots, a quality level that, for the purpose of sampling inspection, is the limit of a satisfactory process average. Acceptance criteria Specification criteria for acceptance of individual product or service characteristics. Sometimes, as in acceptance sampling, the term "acceptance criteria" is used for a set of several characteristics rather than an individual characteristic. Acceptance inspection Inspection to determine whether an item or lot delivered or offered for delivery is acceptable. Acceptance number The maximum number of defects or defectives allowable in a sampling lot for the lot to be acceptable. Acceptance sampling Sampling inspection in which decisions are made to accept or not to accept a lot (or other grouping of product, material, or service) based on the results of a sample or samples selected from that lot. Acceptance control chart A graphical method for the dual purposes of evaluating a process in terms of: (a) whether or not it can be expected to satisfy product or service requirements for the characteristic(s) being measured, and (b) whether or not it is in a "state of statistical control" with respect to within-sample or sub-group variability. Also see “Acceptance Control Chart Example”.
  36. 36. Quality Definitions – Page 2 (Return to Index) Acceptance sampling plan A specific plan that indicates the sampling sizes and associated acceptance or nonacceptance criteria to be used. Accreditation Certification by a recognized body of the facilities, capability, objectivity, competence and integrity of an agency, service or operational group or individual to provide the specific service or operation needed. Accreditation body An organization with authority to accredit other organizations to perform services such as quality system certification. Accredited registrars Accredited Registrars are qualified organizations certified by a national body to perform audits to the QS9000 standard and to register the audited facility as meeting these requirements for a given commodity. Acceptable Quality Level (AQL) AQL is limit of a satisfactory process average at a particular quality level when a continuing series of lots is considered. Also called “average quality level”. Accuracy The closeness of agreement between an observed value and an accepted reference value. Also see “precision”. ACLASS Accreditation Services An ANSI-ASQ National Accreditation Board company that provides accreditation services for: testing and calibration laboratories in accordance with ISO/IEC 17025; reference material producers in accordance with ISO Guide 34; and inspection bodies in accordance with ISO/IEC 17020. Activity Based Costing (ABC) A system for making business decisions based on cost information of fundamental business activities as tasks related to product design, development, quality, manufacturing, distribution, customer acquisition, service and support. ABC is sometimes considered a form of business process re-engineering as it insists on surfacing a manageable number of cost drivers that can be used to trace variable business costs to customer, products and processes.
  37. 37. Quality Definitions – Page 3 (Return to Index) Activity network diagram An arrow diagram used in planning. Also see “Activity Network Diagram Example”. Advanced Product Quality Planning (APQP) A structured method of defining the steps necessary to ensure that a product satisfies the customer. In the automotive industry, APQP is a systematic product introduction process that aims to facilitate supply chain communication and ensure quality throughout the vehicle development process. It is used during the design and development of new vehicles and component systems to reduce the risk of unexpected failure due to errors in design and manufacture.

Quality Definitions – Page 5 (Return to Index) Analysis of Means (ANOM) A statistical procedure for troubleshooting industrial processes and analyzing the results of experimental designs with factors at fixed levels. It provides a graphical display of data. Ellis R. Ott developed the procedure in 1967 because he observed that nonstatisticians had difficulty understanding analysis of variance. Analysis of means is easier for quality practitioners to use because it is an extension of the control chart. In 1973, Edward G. Schilling further extended the concept, enabling analysis of means to be used with non-normal distributions and attributes data in which the normal approximation to the binomial distribution does not apply. This is referred to as analysis of means for treatment effects. Also see “Analysis of Means (ANOM) Chart Example”.

To ensure that corrective and preventive actions are effective, the systematic investigation of the failure incidence is pivotal in identifying the corrective and preventive actions undertaken. CAPA is part of the overall quality management system (QMS). Correlation (statistical) A measure of the relationship between two data sets of variables.
  57. 57. Quality Definitions – Page 23 (Return to Index) 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). Cost of Quality (COQ) The price of nonconformance (Philip B. Crosby) or the cost of poor quality (Joseph M. Juran), the term 'Cost of Quality', refers to the costs associated with providing poor quality product or service. Quality processes cannot be justified simply because "everyone else is doing them" - but return on quality (ROQ) has dramatic impacts as companies mature. Research shows that the costs of poor quality can range from 15%-40% of business costs (e.g., rework, returns or complaints, reduced service levels, lost revenue). Most businesses do not know what their quality costs are because they do not keep reliable statistics. Finding and correcting mistakes consumes an inordinately large portion resource. Typically, the cost to eliminate a failure in the customer phase is five times greater than it is at the development or manufacturing phase. Effective quality management decreases production costs because the sooner an error is found and corrected, the less costly it will be. Cost of quality comprises of four elements: 1 External Failure Cost Cost associated with defects found after the customer receives the product or service ex: processing customer complaints, customer returns, warranty claims, product recalls. 2 Internal Failure Cost Cost associated with defects found before the customer receives the product or service ex: scrap, rework, re-inspection, re-testing, material review, material downgrades. 3 Inspection (appraisal) Cost Cost incurred to determine the degree of conformance to quality requirements (measuring, evaluating or auditing) ex: inspection, testing, process or service audits, calibration of measuring and test equipment. 4 Prevention Cost Cost incurred to prevent (keep failure and appraisal cost to a minimum) poor quality ex: new product review, quality planning, supplier surveys, process reviews, quality improvement teams, education and training.
  58. 58. Quality Definitions – Page 24 (Return to Index) Count chart (c-chart) A type of control chart used to monitor "count"-type data, typically total number of nonconformities per unit. It is also occasionally used to monitor the total number of events occurring in a given unit of time. The c-chart differs from the p-chart in that it accounts for the possibility of more than one nonconformity per inspection unit. Also see “Control Chart Examples”. 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. Also see “Control Chart Examples”. Cpk index Equals the lesser of the USL minus the mean divided by 3 sigma (or the mean) minus the LSL divided by 3 sigma. The greater the Cpk value, the better. Also see “differentiating Cpk and Ppk values”. Critical to Quality (CTQ) tree Used to decompose broad customer requirements into more easily quantified requirements. CTQs are what the customer expects of a product. The spoken needs of the customer. These needs would then be converted to measurable terms using tools such as DFMEA, etc. Critical Characteristics (CC) (in FMEA) Critical Characteristics are those product requirements (dimensions, performance tests) or process parameters that can affect compliance with government regulations of safe vehicle/product function and which require specific supplier, assembly, shipping, or monitoring and inclusion on Control Plans. Critical characteristics are identified with the inverted delta symbol. Critical input(s) x’s input for the tools (FMEA, DOE, SPC, etc.) and significant process knowledge have proved to have a major impact on the variability of the y’s. Critical process(es) Process(es) that present serious potential dangers to human life, health and the environment or that risk the loss of significant sums of money or customers. Critical product measurements Statistical measurements of the process capability in terms of its design specifications (limits) and performance (variability). Used in quality control, Cpk takes into account both accuracy (centering) and precision (dispersion) and helps determine the cause of failures and the need for changes in the product design, tooling, or the manufacturing process. Higher the Cpk value, greater the indication that the process is consistently under control (is within limits). A Cpk value of 1.33 is considered the minimum and, as it nears 2.0, the process approaches six sigma value meaning there are only 3.4 defective units out of one million produced. Also see “process capability”.
  59. 59. Quality Definitions – Page 25 (Return to Index) Cross functional A term used to describe a process or an activity that crosses the boundary between functions. A cross functional team consists of individuals from more than one organizational unit or function. Cross pilot See “scatter diagram”. Cultural resistance A form of resistance based on opposition to the possible social and organizational consequences associated with change. Culture change A major shift in the attitudes, norms, sentiments, beliefs, values, operating principles and behavior of an organization. Culture, organizational A common set of values, beliefs, attitudes, perceptions and accepted behaviors shared by individuals within an organization. Cumulative Sum control charts (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. The CUSUM approach uses the current and recent past process data to detect small to moderate shifts in the process average or variability. CUSUM stands for "cumulative sum" of deviations from the target and puts equal weight on the current and recent past data. Also see “Cumulative Sum Control Chart Example”. Current controls (in FMEA) The mechanisms (for both design and process) which prevent the cause of the failure mode from occurring, or detect the failure mode, should it occur, before the product reaches your customer. For example, current controls include SPC, inspections, written procedures, training, preventive maintenance and all other activities that ensure a smooth running process. Current Good Manufacturing Practices (CGMP) Regulations enforced by the U.S. Food and Drug Administration for food and chemical manufacturers and packagers. Current Reality Tree (CRT) A way of analyzing many system or organizational problems at once. By identifying root causes common to most or all of the problems, the CRT can greatly aid focused improvement of the system. (Part of the Theory of Constraints Thinking Process) Also see “Current Reality Tree Example”.
  60. 60. Quality Definitions – Page 26 (Return to Index) Customer See “external customer” and “internal customer”. Customer delight The result of delivering a product or service that exceeds customer expectations. 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. Customer Satisfaction Index (CSI) Introduced in 1994 by University of Michigan's Ross School of Business - CSI measures customer satisfaction at national level. Customer-Supplier Model (CSM) A model depicting Inputs flowing into a work process that, in turn, add value and produce Outputs delivered to a customer. Also called “customer-supplier methodology”. Customer-supplier partnership A long-term relationship between a buyer and supplier characterized by teamwork and mutual confidence. The supplier is considered an extension of the buyer’s organization. The partnership is based on several commitments. The buyer provides long-term contracts and uses fewer suppliers. The supplier implements quality assurance processes so incoming inspection can be minimized. The supplier also helps the buyer reduce costs and improve product and process designs. Cycle A sequence of operations repeated regularly. Cycle Line Layout (CLL) CLL provides a visual overview (to depict opportunities to eliminate waste, which enables process optimization) of a manufacturing process including - Operator Type (Direct/Indirect) and Percentage Utilization of Direct Labor, Operator Density by Workstation, Station Pitch, Line Side Layout including stock & stock storage methods & Identification of main fixed facilities. Cycle Time (C/T) Time that elapses between one product exiting the process to the next product coming out or the time it takes to complete a process step; typically the value-added time. 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”.
  61. 61. Quality Definitions – Page 27 (Return to Index) Data A set of collected facts. There are two basic kinds of numerical data: measured or variable data, such as “16 ounces,” “4 miles” and “0.75 inches;” and counted or attribute data, such as “162 defects.” Data analysis Breaking down the data to draw significant insights. Steps involved in data analysis - validate (make sure that the data is good), summarize (compute central tendency and dispersion), assess (histograms, etc) search for structure (relationship between variables with scatter plots, correlation, regression, etc), compare (mean, standard deviation, etc) and present results and draw conclusions. 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 An event of nonconformance to specification. Occurrence is measured in DPU (Defects Per Unit), DPO (Defects Per Opportunity), DPMO (Defects Per Million Opportunities) or Sigma Level. A given unit may have any number of defects - based on the number of opportunities. A unit with one or more defects is defective. Defects are caused by errors and measured using c-chart or u-chart. A binomial distribution characterizes defectives. There are four classes of defects: class 1, very serious, leads directly to severe injury or catastrophic economic loss; class 2, serious, leads directly to significant injury or significant economic loss; class 3, major, is related to major problems with respect to intended normal or reasonably foreseeable use; and class 4, minor, is related to minor problems with respect to intended normal or reasonably foreseeable use. Also see “blemish”, “imperfection” and “nonconformity”. Defective A defective unit; a unit of product that contains one or more defects with respect to the quality characteristic(s) under consideration. Define, Measure, Analyze, Improve, Control (DMAIC) An improvement system for existing processes which fall below specifications and need to be improved incrementally.
  62. 62. Quality Definitions – Page 28 (Return to Index) Define, Measure, Analyze, Design, Verify (DMADV) An improvement system intended to develop new processes and/ or products at Six Sigma quality levels. Delighter A feature of a product or service that a customer does not expect to receive but that gives pleasure to the customer when received. Also called an “exciter”. Delphi method A systematic, interactive forecasting method which relies on a panel of experts. The experts answer questionnaires in two or more rounds. After each round, a facilitator provides an anonymous summary of the experts’ forecasts from the previous round as well as the reasons they provided for their judgments. Thus, experts are encouraged to revise their earlier answers in light of the replies of other members of their panel. Since its creation, the method has been used frequently to make predictions, seek consensus and generate ideas. The technique recognizes human judgment as legitimate and useful contribution and allows experts to generate ideas systematically for a complex problem. 1. Form the team 2. Selection of experts - most studies use a 15-35 member panel 3. Develop the first set of question or issues for idea generation 4. Transmission of the first set of questions to experts 5. Analysis of the first round of responses and feedback 6. Preparation and transmission of the second set of questions 7. Analysis of the second round of responses 8. Resolution Demerit chart (d-chart) A control chart for evaluating a process in terms of a demerit (or quality score); in other words, a weighted sum of counts of various classified nonconformities. Also see “Control Chart Examples”. Deming cycle Another term for the plan-do-study-act cycle. Walter Shewhart created it (calling it the plan-do-check-act cycle), but W. Edwards Deming popularized it, calling it plan-do- study-act. Also see “plan-do-check-act cycle. Deming prize Award given annually to organizations that, according to the award guidelines, have successfully applied companywide quality control based on statistical quality control and will continue to do so. Although the award is named in honor of W. Edwards Deming, its criteria are not specifically related to Deming’s teachings. There are three separate divisions for the award: the Deming Application Prize, the Deming Prize for Individuals and the Deming Prize for Overseas Companies. The award process is overseen by the Deming Prize Committee of the Union of Japanese Scientists and Engineers in Tokyo.
  63. 63. Quality Definitions – Page 29 (Return to Index) Deming's 14 points 1. Establish Constancy of Purpose: plan and manage to the plan; detect and correct deviations. 2. Improve constantly and forever every system of production and service: small continuous improvement is better than infrequent quantum leaps. 3. Eliminate numerical goals and quotas, including management by objective: unsupported arbitrary objectives can be both restrictive & demoralizing. 4. Eliminate fear so that everyone may work effectively for the Company: mistakes happen and fear of disclosure impedes correction. 5. Institute leadership: managers must not be cops or directors but rather coaches of the creative team. 6. End the practice of awarding business largely on the basis of price: product quality, product improvement and reliability of supply are important. 7. Break down the barriers between departments: encourage communication and cooperation - eliminate chimneys and silos. 8. Institute training on the job: as product and process content grows, not all employees come equally prepared. 9. Eliminate the annual rating or merit system: performance is subject to variation whereas shared reward develops teamwork. 10.Institute a vigorous program of education and self-improvement: as employees promote the company, the company must develop its employees. 11.Eliminate slogans and exhortations: management, not an individual worker, is responsible for system performance. 12.Cease dependence on mass inspection: it is impractical to sort quality into a system that produces bad product. 13.Adopt the new philosophy: every department of the company can quantitatively measure its productivity. 14.Create a structure in top management to accomplish the transformation: successful systems can only be introduced and maintained by top management. Density function The function which yields the probability that a particular random variable takes on any one of its possible values. Dependability The degree to which a product is operable and capable of performing its required function at any randomly chosen time during its specified operating time, provided that the product is available at the start of that period. (Non-operation related influences are not included.) Dependability can be expressed by the ratio: time available divided by (time available + time required). Dependent events Events that occur only after a previous event.
  64. 64. Quality Definitions – Page 30 (Return to Index) Deployment Dispersion, dissemination, broadcasting or spreading communication throughout an organization, downward and laterally. Also see “cascading”. Detection (in FMEA) An assessment of the likelihood that the current controls (design and process) will detect the cause (process weakness) of the failure mode, should it occur, thus preventing it from reaching your customer; the customer in this case could be the next operation, subsequent operations, or the end user. Design The planning that lays the basis for the making of every object or system. Most commonly linked with engineering. It can be used both as a noun and as a verb. • As a verb, "to design" refers to the process of originating and developing a plan for a product, structure, system, or component with intention. • As a noun, "a design" is used for either the final (solution) plan (e.g. proposal, drawing, model, description) or the result of implementing that plan in the form of the final product of a design process. Design Failure Mode Effects Analysis (DFMEA) The application of the Failure Mode and Effects Analysis method specifically to product design. It is a paper-and-pencil analysis method used in engineering to document and explore ways that a product design might fail in real-world use. A DFMEA documents the key functions of a design, the primary potential failure modes relative to each function and the potential causes of each failure mode. The DFMEA method allows the design team to document what they know and suspect about a product's failure modes prior to completing the design, and then use this information to design out or mitigate the causes of failure. See also FMEA. Design for Manufacturability and Assembly (DFMA) A simultaneous engineering method designed to optimize the relationship between design function, manufacturability, and ease of assembly. Design for Six Sigma (DFSS) A separate and emerging business process management methodology related to traditional Six Sigma. While the tools and order used in Six Sigma require a process to be in place and functioning, DFSS has the objective of determining the needs of customers and the business, and driving those needs into the product solution so created. DFSS is relevant to the complex system/product synthesis phase, especially in the context of unprecedented system development. It is process generation in contrast with process improvement. Design information checklist A mistake proofing checklist designed to assure that all important items were considered in establishing design requirements.
  65. 65. Quality Definitions – Page 31 (Return to Index) Design of Experiment (DOE) DOE is a systematic approach to investigation of a system or process. A series of structured tests are created in which planned changes are made to the input variables of a process or system. The effects of these changes on a pre-defined output are then assessed. 'One change at a time' testing always carries the risk that the experimenter may find one input variable to have a significant effect on the response (output) while failing to discover that changing another variable may alter the effect of the first (i.e. some kind of dependency or interaction). This is because the temptation is to stop the test when this first significant effect has been found. In order to reveal an interaction or dependency, 'one change at a time' testing relies on the experimenter carrying the tests in the appropriate direction. In terms of resource the exact length and size of the experiment are set by the design (i.e. before testing begins). DOE is important as a formal way of maximizing information gained while resources required. It has more to offer than 'one change at a time' experimental methods, because it allows a judgment on the significance to the output of input variables acting alone, as well input variables acting in combination with one another. DOE can be used to find answers in situations such as "what is the main contributing factor to a problem?", "how well does the system/process perform in the presence of noise?", "what is the best configuration of factor values to minimize variation in a response?" etc. In general, these questions are given labels as particular types of study. In the examples given above, these are problem solving, parameter design and robustness study. In each case, DOE is used to find the answer; the only thing that marks them different is which factors would be used in the experiment. The order of tasks to using this tool starts with identifying the input variables and the response (output) that is to be measured. For each input variable, a number of levels are defined that represent the range for which the effect of that variable is desired to be known. An experimental plan is produced which tells the experimenter where to set each test parameter for each run of the test. The response is then measured for each run. The method of analysis is to look for differences between response (output) readings for different groups of the input changes. These differences are then attributed to the input variables acting alone (called a single effect) or in combination with another input variable (called an interaction). DOE is team oriented with a variety backgrounds (e.g. design, manufacturing, statistics etc.) should be involved when identifying factors and levels and developing the matrix as this is the most skilled part. Moreover, as this tool is used to answer specific questions, the team should have a clear understanding of the difference between control and noise factors. In order to draw the maximum amount of information a full matrix is needed which contains all possible combinations of factors and levels. If this requires too many experimental runs to be practical, fractions of the matrix can be taken dependent on which effects are of particular interest. The fewer the runs in the experiment the less information is available.
  66. 66. Quality Definitions – Page 32 (Return to Index) Design record Engineering requirements typically contained in various formats; examples include engineering drawings, math data and referenced specifications. Designing in quality versus inspecting in quality. Also see “prevention versus detection”. Design reviews A proactive procedure to prevent problems and misunderstandings during the design and development of a product or process. Design validation Testing to ensure that product conforms to defined user needs and/or requirements. Design validation follows successful design verification and is normally performed on the final product under defined, operating conditions. Multiple validations may be performed if there are different intended uses. Design Verification (DVER) Testing to ensure that all design output(s) meet design input requirements. Design verification may include activities such as: Design Review, Performing Alternate Calculations, Understanding Tests & Demonstrations and Review of Design Stage Documents before Release. Design Verification Plan and Report (DVP&R) Summary form which lists each individual test, when it was performed, the specification, results and the assessment pass/fail. Part of PPAP. Deviation In numerical data sets, the difference or distance of an individual observation or data value from the center point (often the mean) of the set distribution. Diagnosis The activity of discovering the cause(s) of quality deficiencies; the practice of investigating symptoms, collecting and analyzing data, and conducting experiments to test theories to determine the root cause(s) of deficiencies. Diagnostic journey and remedial journey A two-phase investigation used by teams to solve chronic quality problems. In the first phase, the diagnostic journey, the team journeys from the symptom of a chronic problem to its cause. In the second phase, the remedial journey, the team journeys from the cause to its remedy. Discrimination (in MSE) The technological ability of the measurement system to adequately differentiate between measured values for a selected parameter.
