Đăng bởi: Productivity and quality managementQuality assurance/quality control (QA/QC)
Quality assurance/quality control (QA/QC): Two terms that have many interpretations because of the multiple definitions for the words assurance and control. For example, assurance can mean the act of giving confidence, the state of being certain or the act of making certain; control can mean an evaluation to indicate needed corrective responses, the act of guiding or the state of a process in which the variability is attributable to a constant system of chance causes. (For a detailed discussion on the multiple definitions, see ANSI/ISO/CiCC A3534 2, StatisticsVocabulary and SymbolsStatistical Quality Control.) One definition of quality assurance is: all the planned and systematic activities implemented within the quality system that can be demonstrated to provide confidence that a product or service will fulfill requirements for quality. One definition for quality control is: the operational techniques and activities used to fulfill requirements for quality. Often, however, quality assurance and quality control are used interchangeably, referring to the actions performed to ensure the quality of a product, service or process.
Đăng bởi: Productivity and quality managementQuality audit
Quality audit: A systematic, independent process of gathering objective evidence to determine whether audit criteria are being met. Audits are based on a sample and are independent of the system, process or product being audited, unlike verification activities, which are part of a process.
Đăng bởi: Productivity and quality managementQuality capability

Đăng bởi: Productivity and quality managementQuality capable process
A process that is capable of realizing a unit that fulfills the quality requirements for this unit. (DGQ Volume 11 04:2009). The CP and CPK values are indicators used to review processes. The Cp value indicates the dispersion of a quantitative variable with respect to the specification limits. The Cpk value additionally takes the position of the limiting values into account. These indicators are defined in such a way that a process that is just barely usable is assigned a value of 1.
Đăng bởi: Productivity and quality managementQuality capable process The distinguishing features are:
Systematic influences no longer interfere with the process. The measured values vary only due to random influences. The distribution of the measured values is stable over time. It is possible to predict future measurement series. The process lies within the tolerance range and has sufficient safety margins to the limiting values.
Đăng bởi: Productivity and quality managementQuality characteristic

A characteristic that is assigned to a product, process, or system (e.g. the price or owner of a product) is not seen as a quality characteristic of that product, process, or system. (On the basis of ISO 9000:2015)

Đăng bởi: Productivity and quality managementQuality department
That part of the organizational structure that deals primarily with quality management activities. On the basis of the quality policy, the quality department specifies objectives and responsibilities in order to satisfy legitimate customer requirements. Its assignment is the planning, control, assurance and improvement while using all available resources, such as finances, personnel and equipment. In a certain sense, quality management is the task of all employees.

Đăng bởi: Productivity and quality managementQuality Function Deployment
Method in quality management that is used to conceive, manufacture and sell products and services that are what the customer really wants. All departments are included in this process. Yoji Akao from Japan developed this method as a basic concept for quality planning. The QFD quality method is one of the methods that is used to prevent nonconformities. It is used during the product planning phase. QFD is often called the voice of the customer. This is because QFDs systematic approach does not end with the comparison of customer requirements and product characteristics. Instead, it continues through to the observation of process characteristics in line with the requirements.
Đăng bởi: Productivity and quality managementQuality function deployment (QFD)
Quality function deployment (QFD): A structured method in which customer needs or expectations are translated into appropriate technical requirements for each stage of product development and production. The QFD process is often referred to as listening to the voice of the customer.

Đăng bởi: Productivity and quality managementQuality loss function
Quality loss function: A parabolic approximation of the quality loss that occurs when a quality characteristic deviates from its target value. The quality loss function is expressed in monetary units: the cost of deviating from the target increases quadratically the farther the quality characteristic moves from the target. The formula used to compute the quality loss function depends on the type of quality characteristic being used. The quality loss function was first introduced in this form by Genichi Taguchi.
