How do you get test your designs on existing users?

8 days ago from , Digital Product Designer at Draugiem Group

If you work on a product, that has some amount of users already, and have to make some new design decisions before developing it. What way of user testing works best for you? Do you cherry pick them? Send an email? Have a dedicated test user group? How do you contact them and how do you run the test. Is it scheduled 1:1 interviews, or just passive questionnaires, that they can fill out whenever.

I want to get some feedback before moving into development. Just to be sure that everything is good on a large scale. Later on, I can narrow down with A/B testing.

Thanks already! :)
