On Sunday, May 20th, 2018, I attended the Design Frontiers: Healthcare challenge. Design Frontiers is a day-long design sprint with lightning talks focusing on applying human-centered design to the field of healthcare. This sprint had special guest, Illumina, giving us a chance to improve their digital and physical products. We divided up into groups of 4 and began the sprint.
Each team was given four hour to Redesign the NextSeq 550Dx Operating Software(NOS), a medical device sequencer used clinically by hospitals and commercial labs to diagnose and treat disease in patients.
To get us started Illumina provided us with an Interactive Prototype of the existing NOS and a few key goals to keep in mind.
" Due to the nature and purpose of this sequencer, it is highly important for the NOS to have an optimized usability and user experience. A seamless, straightforward, and easy-to-use experience is necessary to prevent use errors and ensure accuracy of patient test results. Currently, the NOS has opportunities for improvement in usability, including improving the way the information is structured to increase findability of content/functions. "
" Your team’s challenge is to redesign the NOS homepage and “Sequence”
workflow screens (the screens that come after clicking on the “Sequence” button. Improve its usability and modernize the visual design while evoking the spirit of the Illumina brand. Use the Illumina Brand Guideline to get familiar with the essence of Illumina’s brand identity and show us your interpretation of it in your prototype. Be creative! The sky's the limit! "
Since the users of the device will all be trained researchers, our group interviewed the four healthcare guest lecturers attending the event. We went through each page of the mock-up with them to identify the key problems they had using the interface.
Many of them reported being unsure what many of the buttons afford, felt much of the information they were receiving was unnecessary, and found when the device displayed errors, they were unclear and provided little instruction.
We also read through the documentation on Illumina's Brand Guidelines to ensure that we would keep the spirit of the Illumina brand.
We used Figma to create a digital prototype. To solve the problems we found, we changed the buttons in the device to more universal standard icons, we used text size and Illumina-brand colors to guide the user more easily through the Loading Process, and moved much of the "excessive" information confusing users into a settings tab, accessible at any point moving through the workflow screens.
