Knowledge, skills and method constitute the fundamental basis for design education which is effective in the current competitive international scenario, where differences are ever slighter and specificity of locations must become innovative within a constant process of creativity and invention. The design education process, as well as the discipline of design, must also constantly be enriched with the multidisciplinary character of the industrial product and the expanded number of end users, who are ever more sensitive and demanding, and can be satisfied through the configuration of inclusive products. This contribution illustrates a proposed new inclusive and integrated methodology designed to initiate new design and experimental itineraries, excluding schemes, rules, tools and applicative logic that at times result in rigid industrial design discipline. An inclusive design methodology defined by critical and analytical recognition, of classic industrial product design methods hypothesized between 1962 and 1981; from the selection of contemporary design methods based on User Center Design and from the design experience. This is a methodical tool capable of transferring logical and systematical criteria through scientific references to the creation, management and implementation of complex systems, via inclusive design principles and integration, enabling all users to take advantage of comfortable and pleasant use. The method assumes multidisciplinary value thanks to the necessary intersections of several disciplines, such as ergonomics, multisensory aspects, economy, social sciences and other disciplines, based on the criteria of simplicity, unequivocalness, adaptability, correspondence with a conceptual model, constant feedback, tolerance for errors, accessibility, affordance, mapping and finally, the principle of usability, all of which guide and represent the fundamental reference points for the creation of “universal design”, delineating the rules and guidelines for the development and construction of “good design”.
