I’m so sorry for the long delay in responding! I’m glad you enjoyed reading this work. :) To my knowledge the portal was very, very slow in changing in terms of functionality or aesthetics (it was running on Microsoft Silverlight, which just about killed me). They may have modified it since I was working on this migration, but my guess is it would be very subtle since the primary stakeholders were the Electronic Health Record vendors, not the patients themselves—a sign of a very dysfunctional system, to be sure.
I bet that fixed mindset issue resonates as a dev! Hopefully this helps you help audience members communicate with you more effectively so you can do your part to assist them better.
