U.S. Department of the Interior

Responsible for managing and conserving the nation's natural resources and cultural heritage. They oversee the management of public lands, including national parks, wildlife refuges, and federal territories. Additionally, the department plays a vital role in promoting responsible energy development, protecting endangered species, and fostering tribal relations.


The U.S. Department of the Interior's website is a crucial platform for sharing information and policies related to the nation's natural and cultural heritage. However, some users may find it less user-friendly due to factors like complex navigation, overwhelming content organization, outdated design, and limited accessibility features. These challenges make it difficult for users to locate and understand information, hampering their experience and potentially reducing public engagement.

Insight Statements


During initial research interviews, it was discovered that users struggled with the informational hierarchy and were having trouble finding what they were looking for. 


Therefore, we believe that users want to feel more confident when using the Department of the Interiors website when researching things related to conservation, National parks, Native American relations and much more


We might do this by providing a website with organized information hierarchy with a user interface that is friendly to any user. Doing this will allow the user to trust the information posted on the site and allow them to search/navigate the site without frustration.

Site Mapping

Card Sorting

 Since the DOI website is used as a hub for numerous additional government sites. the current organization makes it difficult to locate resources a visitor may be looking for. To better structure how Information was organized on the website, I had users sort cards to what they thought would make the most sense.
