The increasingly transdisciplinary context of design, where designers collaborate with other disciplinary and domain experts, means there is a growing need to evidence the effectiveness of design methods. We address this need in two ways. First, we propose a ‘chain of evidence’, from motivation to claims, operationalising this in a systematic assessment framework. Second, we systematically review current design method research. Our results reveal that while all links in the chain of evidence are reported across the literature and best practices can be identified, no individual paper either reports all links or consistently achieves best practice. Our framework and results demonstrate the need for standards of evidence in this area, with implications for design method research, development, education, and practice.@en

Delft Design Guide provides an overview of the perspectives, models, approaches, and methods used in the bachelor's and master's curriculum of Industrial Design Engineering at Delft University of Technology (TU Delft). Some of these are unique to the university, others are well known and are used by designers worldwide. Designing products and services at this faculty is considered a systematic and structured activity, deliberately and purposefully, and with moments of increased creativity. The methods and techniques are each described in a practical one-page text, illustrated for further clarification and enriched with images that should encourage reflection and further reading. Design students can use the book as a reference guide in their design projects and in managing their personal development. Design teachers can use the book as a reference guide to assist students in learning a method. Design professionals can use the book as a reference guide to support their design processes @en
