Process
01
Decision journey mapping
Mapped where confidence drops in the decision process. Users lose trust when they can't verify where a recommendation comes from.
02
Interaction model testing
Tested three models: chat, structured form, and hybrid. Single input with structured output was the fastest path to a decision.
Solution
01
Natural language input
One text field. No forms or onboarding. Users describe what they need and get results.
02
Cited recommendations
Every result links to its source. Users verify the reasoning themselves.
03
Comparison view
Shows only the factors that separate options. Users ask followup questions to narrow results.
