Our user research process investigating and characterizing scientific data change. We conducted four exploratory semi-structured interviews with astronomers and earth scientists. We learned about data change in their work and gathered feedback on statistical analyses created by our team. Findings were used to generate design requirements for a data change tool. Next we conducted twelve domain science semi-structured interviews to better understand how scientists and projects handle data change, created user interface mockups to explore representations of change analyses, and evaluated a prototype of our tool through six usability evaluations.
