Thus, with a clear definition of customer driven functions, we can craft job descriptions and tasks to take advantage of the abilities of people with disabilities.

Analysis of Means (ANOM) Developed by Ellis R. Ott in 1967 (later enhanced by Edward Schilling), ANOM is 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 non-statisticians had difficulty understanding analysis of variance. 

Analysis of Variance (ANOVA) a basic statistical technique for analyzing experimental data. It subdivides the total variation of a data set into meaningful component parts associated with specific sources of variation in order to test a hypothesis on the parameters of the model or to estimate variance components. 

Analysis(1) To separate into elemental parts or basic principles so as to determine the nature of the whole (2) A course of reasoning showing that a certain result is a consequence of assumed premises. (3) (ANSI) The methodical investigation of a problem, and the separation of the problem into smaller related units for further detailed study.

ANALYTIC NETWORK PROCESS The Analytic Network Process (ANP), though based on the Analytic Hierarchy Process, is a system for the analysis, synthesis, and justification of complex decisions with the capability to model non-linear relations between the elements. ANP allows the decision maker(s) to leap beyond the traditional hierarchy to the interdependent environment of network modeling. The ANP is designed for problems characterized by the added complexity of interdependencies such as feedback and dependencies among problem elements. Using a network approach makes it possible to represent and analyze interactions, incorporate non-linear relations between the elements, and synthesize mutual effects by a single logical procedure.

Analytical Hierarchy Process (AHP) Developed by Thomas Saaty, AHP provides a proven, effective means to deal with complex decision making and can assist with identifying and weighting selection criteria, analyzing the data collected for the criteria and expediting the decision-making process.

ASSIGNABLE CAUSE - A source of variation which is non-random; a change in the source ("VITAL FEW" variables) will produce a significant change of some magnitude in the response (dependent variable), e.g., a correlation exists; the change may be due to an intermittent in-phase effect or a constant cause system which may or may not be highly predictable; an assignable cause is often signaled by an excessive number of data points outside a control limit and/or a non-random pattern within the control limits; an unnatural source of variation; most often economical to eliminate.

ATTRIBUTE - A characteristic that may take on only one value, e.g. 0 or 1. 

Attribute A property or characteristic that is common to some or all of the instances of an entity. An attribute represents the use of a domain in the context of an entity. 

Attribute Data - Numerical information at the nominal level; subdivision is not conceptually meaningful; data which represents the frequency of occurrence within some discrete category, e.g., 42 solder shorts.

Attribute(s) Data 1. Product, process , or component data that is qualitative, rather than quantitative in nature. 2. Product, process , or component data that is measured strictly by either conforming or not. 

 Attributes data are qualitative data that can be counted for recording and analysis. Examples include the presence or absence of a required label, the installation of all required fasteners. Attributes data are not acceptable for production part submissions unless variables data cannot be obtained. The control charts based on attribute data are percent chart, number of affected units chart, count chart, count-per-unit chart, quality score chart, and demerit chart. 

Attributes data Data that is counted in discrete units such as dollars, hours, items, and yes/no options. The alternative to attributes data is variables data, which is data that is measured on a continuous and infinite scale such as temperature or distance. Charts that use attribute data include bar charts, pie charts, Pareto charts and some control charts.
