Deliver
Prototypes expand to cover edge cases, role differences, and full states — moving closer to real product behaviour. Deeper usability sessions with 6−10 users, combined with stakeholder reviews, reveal what still doesn’t work.
The best solution isn’t the ideal one — it’s the best one that can actually ship. On Travelata, legacy code made full parameter sync impossible. I evaluated three approaches and proposed a compromise that delivered 80% of the value at 30% of the technical cost. On Document Base, security constraints shaped the change history feature — I designed it to serve both compliance needs and user transparency.
Final deliverables include refined UI, clear copy, accessibility, responsive behaviour, and success metrics tied to the design — conversion, task completion, time-to-task, satisfaction scores
