A three-step scenario and sticky shortcuts were introduced after direct iPhone usability feedback.
CASE STUDY 03 / FRONTLINE OPERATIONS
Workforce Continuity
A mobile-first prototype for handoffs, consent, readiness, next actions, and human reviewer feedback in high-friction frontline work.
PRODUCTWORKFORCETESTED PROTOTYPEINDEPENDENT CONCEPT
01 / HUMAN PROBLEM
A handoff is where continuity disappears.
Frontline work often depends on one person knowing what is ready, what is missing, what can be shared, and who owns the next step. When that person or context disappears, the workflow restarts from memory.
The prototype explores a compact continuity layer that carries readiness, consent, next action, and minimum-necessary context without converting a handoff tool into a giant system of record.
02 / PRODUCT FLOW
Consent is state, not decoration.
STATUS→DOCUMENT READINESS→CONSENT→NEXT ACTION→HANDOFF→AUDIT / REVIEW
Revoked consent persists and blocks handoff/export behavior in the synthetic workflow. Restoring consent can re-enable permitted actions. The UI exposes those consequences rather than treating a checkbox as a one-time formality.
03 / ITERATION
Mobile feedback changed the product.
A later review rail supports typed feedback, free text, share-sheet behavior, clipboard fallback, clear action, and live-region status without a feedback backend.
A separate dry-run control-plane layer can explain blockers and test state transitions without mutating project state or authorizing a build.
04 / EVIDENCE
Usability and authority were tested separately.
Repository evidence records successful persistence/revocation/reset/export behavior and no visible horizontal overflow in the guided synthetic flow.
Hardware keyboard and VoiceOver were human-reported as passing on the v0.2 flow; that evidence remains distinct from automated static checks.
The review surface does not automatically submit, store, analyze, or persist unsent reviewer feedback.
The repository explicitly refused to invent reviewer identity, findings, risks, or recommendations from a blanket test report.
05 / LIMITS
What the prototype refuses to imply.
- No real participant data or private institutional workflow truth.
- No autonomous adverse decision, diagnosis, eligibility decision, or legal/clinical authority.
- No employer endorsement, partnership, deployment, or adoption claim.
- Passing ontology/scenario tests proves internal consistency, not stakeholder validation.
- Feedback itself cannot authorize a product state transition.
WHAT I LEARNED
A human-centered workflow is not safer because it says “consent.” It is safer when revoked consent changes what the software can actually do, and that behavior survives the messy edges of mobile use, refresh, review, and handoff.
