Traditionally, design decisions are made and solutions are developed before understanding the potential outcomes of those decisions. We then validate the solutions, revise decisions, and redesign, creating massive waste in the process. This is the paradox of design. Design optimization techniques and technology (APIs, visual programming, and simulation tools) can help break this paradox by simulating many options and the potential outcomesinforming decisions rather than simply validating them after the fact. This technology will change how we design, much like the advent of Building Information Modeling (BIM) did a decade ago. Therefore, it is critical to understand the fundamental changes to the design process that will be necessary to capitalize on this new technology. This round-table discussion will explore the paradox of design, as well as the challenges of design optimization, lean design processes, simulation technology, and computational design.
