Acceptance quality limit (AQL):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 number: The maximum number of defects or defectives allowable in a sampling lot forthe lot to be acceptable.
Acceptance sampling: Inspection of a sample from a lot to decide whether to accept that lot. There are two types: attributes sampling and variables sampling. In attributes sampling, the presence or absence of a characteristic is noted in each of the units inspected. In variables sampling, the numerical magnitude of a characteristic is measured and recorded for eachinspected unit; this involves reference to a continuous scale of some kind.
Acceptance sampling plan: A specific plan that indicates the sampling sizes and associated acceptance or nonacceptance criteria to be used. In attributes sampling, for example, there are single, double, multiple, sequential, chain and skip-lot sampling plans. In variables sampling, there are single, double and sequentialsampling plans. For detailed descriptions of these plans, see the standard ANSI/ISO/ASQ A3534-2-1993: Statistics—Vocabulary and Symbols—Statistical Quality Control.
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.

Alignment: Actions to ensure that a process or activity supports the organization’s strategy, goals and objectives.American Association for Laboratory Accreditation (A2LA): An organization that formally recognizes another organization’s competency to perform specific tests, types of tests or calibrations.
American Customer Satisfaction Index (ACSI): Released for the first time in October 1994, an economic indicator and cross industry measure of the satisfaction of U.S. household customers with the quality of thegoods and services available to them. This includes goods and services produced in the United States and imports from foreign firms that have substantial market shares or dollar sales.
