Axiomatic design is a
systems design
The basic study of system design is the understanding of component parts and their subsequent interaction with one another.
Systems design has appeared in a variety of fields, including sustainability, computer/software architecture, and sociolog ...
methodology
In its most common sense, methodology is the study of research methods. However, the term can also refer to the methods themselves or to the philosophical discussion of associated background assumptions. A method is a structured procedure for bri ...
using
matrix methods to systematically analyze the transformation of customer needs into functional requirements, design parameters, and process variables.

Axioms
An axiom, postulate, or assumption is a statement that is taken to be true, to serve as a premise or starting point for further reasoning and arguments. The word comes from the Ancient Greek word (), meaning 'that which is thought worthy or f ...
(i.e., given without proof) governing the analysis and
decision making process in developing high quality product or system designs. The two axioms used in Axiomatic Design (AD) are:
* Axiom 1: The Independence Axiom. Maintain the independence of the functional requirements (FRs).
* Axiom 2: The Information Axiom. Minimize the information content of the design.
Axiomatic design is considered to be a design method that addresses fundamental issues in

Coupling is the term Axiomatic Design uses to describe a lack of independence between the FRs of the system as determined by the DPs. I.e., if varying one DP has a resulting significant impact on two separate FRs, it is said the FRs are coupled. Axiomatic Design introduces matrix analysis of the Design Matrix to both assess and mitigate the effects of coupling.
Axiom 2, the Information Axiom, provides a metric of the probability that a specific DP will deliver the functional performance required to satisfy the FR. The metric is normalized to be summed up for the entire system being modeled. Systems with less functional performance risk (minimal information content) are preferred over alternative systems with higher information content.
The methodology was developed by Dr.
Suh Nam Pyo at MIT, Department of Mechanical Engineering since the 1990s. A series of academic conferences have been held to present current developments of the methodology.
