The Axiomatic Design (AD) introduces several benefits for product innovation, but it doesn’t account for all required concerns in product lifecycle. Integrating Design for X (DFX) is proposed here to enhance the results of AD and measure the performance of proposed product designs. The introduced methodology is referred to as Axiomatic Design for X (ADFX). This idea enables adding several design and usage requirements as functional requirements and/or design axioms in addition to design constraints in a flexible framework for product design. Furthermore, this idea can inspire robust mathematical models for product design by agglomerating objective and subjective product requirements. This paper provides a base for other directions in the product design research.
