This paper, authored by me and my colleagues from the Design Methodology Unit, Praxiology Department, 1 was originally published as an editorial in the proceedings of the Conference on Design Methods, organized in Radziejowice near Warsaw, Poland, September 11–13, 1977. The proceedings were published in Design Methods and Theories: Journal of the DMG, Vol. 15, Nos. 2–4, Design Methods Group, San Luis Obispo, CA, 1981. The conference intended to present the results of interdisciplinary research on design and was in fact the beginning of the designological approach to design studies. 2
