Fairfield Pros was selected to improve the user experience of this powerful tool that predicts the survival of mothers and children in developing countries. With usability design techniques we provided short-term and long-term improvement recommendations for the user interface of the Lives Saved Tool (LiST). A key input screen for epidemiologiests was redesigned for easier use.
The engagement included a carefully designed test protocol for face-to-face testing of novice users with remote viewing technology for the John’s Hopkins team to observe. Expert users were also interviewed and observed to determine typical tasks and problems of these more experienced users.
Fairfield Professionals created a document that summarized the usability challenges encountered by the beginners and experienced LiST users as well as recommended changes to LiST, based on usability best practices to address each usability problem. The resulting short-term and long-term design recommendations were readily adopted, to the delight of LiST’s many users.
