Delving into the world of digital product development, customer discovery stands as a cornerstone for successful innovation. It's the secret sauce for tech giants and startups alike, fueling their UX research and product discovery efforts.
The magic, however, lies in posing the right question.
For the UX researcher, product manager, product marketer, or designer in search of that spark, I've curated a compilation of excellent customer interview questions. Each query is a stepping stone to insightful conversations with your users.
These product discovery questions focus on unravelling honest customer stories. Emphasising past customer behaviour and desired future progress.
With each question, I outline the expected outcome, the criteria of an excellent answer, and a snapshot example.
