Designer: It sounds like we’re on the same page about wanting to ship feature X as quickly as possible. I know you want us to start sketching some solutions right now, but a [sanity check, quick validation, etc.] will help us know we’re heading in the right direction. Speed isn’t just about how quickly you jump of the starting block, it’s about how quickly we get across the finish line. And we’ll get there much faster if we can run in a straight line instead of going in circles.
Put another way, focus on why you do research, not the mechanics of how you’ll do it. I’ve listed below some phrases that my team has found to be useful when communicating with non-designers. The section on quantitative research may also be useful for you.
A finance team doesn’t say that they make spreadsheets for a living; they talk about their benefit to the company in terms of how much money they save. Recruiters don’t say that they write emails and make phone calls; they help build teams necessary for a company’s growth. Start to think of research as a way to give value to the company, and be ready to articulate why it’s important using words that other teams will understand.
