This is an activity of local checking, based on a sample used to determine the effective implementation of a documentary quality system by the supplier.
This is a technique used for determining the best practices for a particular product or process.
This is the total amplitude of the variation that is inherent to a stable process. It is determined through the use of data from the control charts. The control graphs must indicate the stability before the capability figures are performed. Histograms are used to examine the distribution of values and to check a normal distribution. When an analysis indicates an abnormal distribution, advanced statistical tools, such as a PPM analysis, will be required in order to determine the capability. If the control charts indicate that the process is not stable, the index can be calculated.
PROCESS STATISTICAL CONTROL
This is the use of statistical techniques, such as the control charts, to analyze a process or its results, as well as to take proper actions to reach and maintain a statistical control state and improve process capability.
This is the complete measuring of all dimensions of parts shown on a drawing. A lay out inspection can be required by some customers for all the products, annually, unless some other frequency is established through a control plan, approved by the customer.
This is a facility for essays and tests that can perform chemical, electrical, physical essays and dependability or validation essays.
This is the supplier document which describes the Quality System elements used for assuring that the customer's requirements, necessities and expectations will be met. The Quality Manual is considered as a level 1 document in the Quality System.
Non conform is a product or material that does not conform with the customer's requirements or specifications.
Non conformity is a process that is not conform with the quality system requirements.
PARTS PER MILLION PPM
PPM is a method for describing the performance of a process in terms of a real non conform material. The PPM data can be used to determine priorities in the corrective actions. The definition of defective units varies according to the customer (Ex.: All, only those found to be wrong, all in the box).
An active part is a part that is being supplied to the customer as an original equipment component or as spare part. The part remains active until the tool scrapping is authorized by the customer's proper sector. Parts which are produced with tools that do not belong to the customer, or in situations where the same tool is used for the manufacturing of several different parts, the authorization for deactivating the part must be confirmed in writing by the customer purchase sector.
CORRECTIVE ACTION PLAN
This is a document that specifies the actions to be implemented for correcting a quality problem or question of a process or of a product, with established responsibilities and dates.
A Reaction Plan is the action specified by a Control Plan or other document from the quality system, to be initiated when a non conform product or instability in the process is identified.
These are documentary evidences that the supplier processes were executed in accordance to the Quality Documentation (Ex. essay result and inspection, internal auditing results, calibration data) and result records.
This is the action taken over non conform products so that they can meet the specified requirements.
This is a disciplined process for problem analysis with the purpose of determining and elimination the root causes of a problem or deviation. The customer's specified requirements include 7 steps (Chrysler), 8 -D (Ford) and PR&F (GP5) - for General Motors.
These are defined as the suppliers of production materials or spare parts or production parts, who directly supply the suppliers of CHRYSLER, FORD AND GENERAL MOTORS, or other customers that may underwrite this document. Here are also included the suppliers of services such as heat treatment, surface treatment, painting and other finishing services.
