As we begin, I think it’s important to have a foundational understanding of the general process our work necessitates. Following the Human Centered Design (HCD), we begin with research (usually ethnographic or interpersonal), it’s output becoming synthesized into insights that allow us to brainstorm, ideate, and prototype (I tend toward set-based design.) This is where we start to see commonalities between the Double Diamond, HCD, Lean, and Agile. Personally, I’m a big fan of Lean as it looks for design feedback sooner and more often. We use this feedback to continue iterating until we meet our goals, eventuating in the development of a fully-functioning product.
