problem
this wasn't a blank-slate project — it was inheriting two years of research scattered across four different agencies (tribeone, ideo, madpow, langland), each with their own low-fidelity screens, their own validation methods, and no single coherent thread tying it together.
my first job wasn't designing screens. it was making sense of what existed.
turning fragmented research into a foundation
i structured the accumulated research into a single usable set of artifacts:
•
a summary of research and key insights
•
assumptions, validations, and recommendations
•
identified research gaps
•
feedback on existing low-fi screens (none of which were clickable yet)
from that, i defined the actual problem statement, goal statement, and value proposition — the groundwork the rest of the team would design against.
prototyping with real clinical input
working within huma's existing design system, i built the first prototype and ran feedback sessions with healthcare professionals across multiple countries — not just patients. getting clinical buy-in early mattered here in a way it doesn't in most consumer products; this app needed to work for nurses and clinicians managing the treatment relationship, not just the end patient.
before testing began, i defined exactly what we'd measure:
•
completion rate per prompt
•
time taken to complete each prompt
•
number of errors or difficulties encountered
•
satisfaction level per module
•
system usability scale (sus) score
testing with patients
i tested the first high-fidelity prototype with 20 patients, running individual interviews at 90 minutes each — a serious time investment per participant, reflecting how much nuance this population's feedback required.
every piece of feedback went into a structured table tracking: observation, evidence, recommendation, type, module, rating, proposed design change, priority, rationale, and whether it became an actionable task. from there, i ran prioritization sessions with the design team based on impact vs. effort, and assigned resulting tasks by each designer's module specialization.
outcome
the app shipped on the app store and play store, having gone through 7 design iterations, each reviewed not just by design but by internal clinical, regulatory, and technical teams at huma.
reported outcomes:
•
increased patients' ability to successfully self-infuse at home
•
increased patient and caregiver confidence and competence managing treatment
•
reduced treatment attrition
•
improved patients' quality of life / reduced burden
•
maintained desirability for healthcare providers, not just patients
what made this different
this wasn't a typical "ship fast, iterate later" product cycle. certain modules (onboarding, profiles, caregivers, journal, medication) were treated as low-risk-of-change and could evolve — but other features were deliberately frozen based on the research-to-date in order to hit regulatory deadlines. balancing clinician needs, patient needs, and regulatory constraints simultaneously is what shaped most of the prioritization calls across those 7 iterations.
