I'm looking for ideas for conducting a quick, valuable design workshop (max a few hours). Only people who are involved in building the related digital product will participate (including me, also part of the team).
The goal is to identify critical UX issues, mostly by looking at the UI, and improve the overall look and feel of the product in the future.
I'm aware of the limitations we have in evaluating product due to every-day contact and co-creation. I'm looking for exercise which helps us to see the product and its problems in a fresh way, break our mental models (is this even possible?). Bring out voices that are hidden every day, too. Any ideas, resources, case studies?
