DiEM25 is a European movement of Democrats, founded in 2015 by former Greek finance minister and economist Yanis Varoufakis and Croatian philosopher Srećko Horvat. I joined DiEM25 as UX Researcher and Designer in July 2017 and I have since been working remotely with the team located around the Europe.
Note: I'm only able to share my work on Information Architecture.
Treejack usability test was used with seven tasks as a way to identify possible problems with navigation. Treejack test was followed by an online card sorting study also using the existing navigation. For both tests, Optimal Workshop (user research and usability testing platform)  was used for testing and data analysis.

Treejack Test (original navigation):
The task questions for Treejack test were composed to reflect the needs of new users that have never visited the website, returning users that are not members, and members of the DiEM25. Some additional user interviews were also conducted after the Treejack test.

Card sorting
The card sorting study included 29 cards from the existing website. Due to some inconsistencies in labelling, cards have been altered slightly for better understanding without the context.

Label Audit
To evaluate usability of the labels Nielsen and Norman's content inventory framework was applied to evaluate and score categories and labels for the links.
