Budi is a designer I’ve admired for a few years now. His advice for building an effective product design portfolio is something I have also told many young designers. A poor portfolio for product designers is when it only shows the artifacts (e.g. the screen). I’d consider it as a weak portfolio. Because it doesn’t help me to know whether a designer can make a good decision or at least have a good line of thinking. I don’t even know if the outcome help the team achieve the goal or learn something.
