Small-sample usability testing still holds up

NN/g's decades-old guidance that 5–8 users surface most usability issues remains the default research method when budget is tight. It's foundational, not fashionable, but juniors still get tested on it.

NN/g's long-standing guidance holds: testing with a handful of users (roughly 5–8) surfaces most major usability issues, and it remains the default method researchers reach for when time and budget are tight. This isn't new or trendy — it's decades-old foundational practice, and it's still what junior researchers get asked to apply in interviews and on the job. The risk for early-career designers is skipping it entirely because 'we don't have budget for research,' when a scrappy 3–5 person guerrilla test costs almost nothing. Practising this on your own portfolio projects is one of the fastest ways to build research experience you can actually talk through.

'Vibe design' is changing how juniors actually work

AI-generated UI ('vibe design') is showing up in real workflows, not just demos — recent coverage argues it's shifting what junior designers spend time on, from pixel-pushing to prompting and curating. Worth testing as an emerging practice, not treating as a guaranteed skill.

Continuous discovery beats big research rounds

Continuous discovery — small, regular user touchpoints instead of big periodic studies — is now treated as established practice on product teams. You don't need a big research budget to start.

AI is nudging designers to test more, guess less

One designer's account of how AI has shifted their process toward faster, rougher first drafts and more testing. It's a single anecdote, but it points at a real methods shift worth reflecting on.
