I’m wary of design principles. I find some inspirational (like my favorite, Salesforce Lightning’s Beauty, which focuses on craft). Yet, in-house teams can spend months defining principles too vague (“Be Magical!”) or generic (“Simplicity!”, as if most efforts crave complexity) to be useful. These principles then surface rarely if ever, even in design discussions that include principle authors.
