We’ve translated the Evidence-Based Design (EBD) process into a designer-friendly tool: The “When can we EBD” diagram prompts designers to consider opportunities for integrating EBD at any point across design and delivery by mapping EBD processes with familiar project cycle phases and practices. Like the design process, it is set up as a spiral to show that repeated application supports continuous improvement. Rather than a formulaic checklist, we’ve included a range of ideas to suggest not only “WHEN”, but also “HOW can we EBD” to establish evidence-based project goals, apply evidence to design, and measure outcomes to add value to our projects.
