The Design Principles & Practices Journal Collection offers an interdisciplinary forum to explore the meaning and purpose of design. In professional and disciplinary terms, the network traverses a broad sweep to construct a trans-disciplinary dialogue, which encompasses a wide array of design paradigms and practices. We move between theoretical reflection on the nature of design and case studies of design practice, and from research-based perspectives to the experience-based perspectives of design insiders. We seek to build an epistemic community to make linkages across disciplinary, geographic, and cultural boundaries. The journal collection is defined by our Research Network scope and concerns and motivated to build strategies for action framed by our shared themes and tensions.
