In my current role we currently produce a large amount of enterprise data visualisations for internal use.
As part of the design process we create mockups and prototype to help us ideate and define potential solutions.
A weak part of the process is how we validate the design of the data visualisation. Typically we will share the prototype and only get a binary response of like it / don’t like it.
Would love to hear if anybody has any experience or knowledge of a robust data visualisation validation process that would ideally include more sophisticated information to help inform design changes.
I have performed usability testing previously for linear journeys in mobile apps, the challenge I see specifically with data visualisations is that the journey is non-linear and could be exponentially branching based on the how the user interprets the data.
Thanks for any help!
