About SWAP
The Surveillance Window Application (SWAP) is a web-based tool that provides information about unfolding disease outbreaks by providing information on historical outbreaks. The SWAP has a library that contains information surrounding 22 diseases and around 500 global outbreaks. Using various analytic factoring, SWAP allows public health analysts to see if there are any historical outbreaks that are similar to current events
The client would like a usability evaluation completed on improving this product for public health professionals and epidemiologists. They would also like recommendations for improvement provided to them.
Goal
Our goal was to provide a usability evaluation with recommendations that SWAP can implement to improve their application. The client have never performed usability testing with participants who were not already associated with the project. The client wanted to improve the use of the website for public health professionals, epidemiologists, and data analysts. Our goal was to perform usability tests to evaluate the overall effectiveness of http://swap.bsvgateway.org/ by testing the navigation, site terminology, and ease of information access.
