Test Line Management System for Pacemaker Units
Micro Systems Engineering
Conceptualized the re-design of the overall operation of Merlin software used for managing the cardiac rhythm management test line system. Worked with domain experts to evaluate the usability of the current hardware & software systems on the production floor. And enhanced the structure with user centric interaction oriented solution.

Test Line Management System for Pacemaker Units
Micro Systems Engineering, Inc. (MSEI) is a leading medical microelectronics development & design, system integration, and manufacturing company. Since 1979, MSEI produces Class III, cardiac rhythm management, neurostimulation, active implant, sensor, Class II, and other microelectronic devices.
MSEI had goals to improve the overall user experience of the production manager and THS which manages the production processes. To control and operate the multiple THSs together the company used Merlin which was a complex software which reflected the real time status of each module's sub unit of the testing line.

I started with learning about the domain which included the background and architecture of the whole technical system along with the competitor review. Since the scope was narrowed down to a dedicated testing system, I was able to understand in depth about Production Manager, THS and Merlin Software Architecture. I conducted stakeholder interviews to learn about the goals and key priorities followed by a guided tour of the cleanroom/production floor where test lines were operating. To understand the usability issues, I conducted user research through shadowing and extensive user interviews & surveys.
I worked on improving the information architecture and sketched the designs for conceptual review. For the high-fidelity I used Adobe XD to design the final mocks.
Due to time constraints the final design was put to test using persona based cognitive walkthrough and stakeholder and user focus groups discussion.
