The ELIXYS is a software-operated radiochemistry instrument used in cancer research and diagnosis. It is used to make radioactive PET "probes", which are then injected into animal or human recipients. This case study takes a brief look at the redesign of the software platform used to operate the machine.
The goal of the redesign effort were mainly to address functionality issues. Key issues were discovered through customer complaints, others were discovered by employing UX methods.
The following design methods were employed to discover UX issues:

The UX methods yielded some interesting insights. This further informed the direction that the redesign needed to take. The key goals from the discovery phase were:
There are 8 major areas of software. Similar elements across these areas had slightly different UI design.
The software has multiple setup constraints. The user is left guessing on these without clear directions or error messages.
4/5 research participants expressed that they follow a specific set of actions in sequence everytime, with minimal deviations.
There is a long wait time between new user training and actual use. Many customers are infrequent users.
