Platform

Benefits portals, configured per client

Mercer Marketplace 365+ is a multi-tenant platform where clients build customized benefits portals, using pre-designed user journeys and configurable content to match their audience, brand and products.

Role

Design strategy for enrollment

I partnered with Mercer to define the design strategy for the enrollment experience, using insights from user testing to turn key product distinctions into clear guidance at every step.

Challenge

Only 1 in 4 chose guidance

Expert Guidance enrollment was a separate, optional path, and despite efforts to promote it, only 1 in 4 users chose it. Abandonment hit 75%, likely because the flow felt overwhelming and the sheer number of choices made it easy to give up.

Solution

Guidance as the default path

I made Expert Guidance the default. The redesigned flow asks a focused set of questions, recommends plans from the answers, and confirms choices before submitting: fewer decisions, clearer direction.

Workflows

From login to confirmation

Testing

Validated in Maze before build

We ran usability tests in Maze before development. They shaped how the Expert Guidance questions were sequenced and how the final plan recommendation works.

Enrollment

Four questions to a matched plan

The guided flow asks four questions about medical needs, care preferences and cost comfort, then recommends a matched plan at the point of selection. Users can still compare plans side by side or review full details before enrolling.

Outcome

Enrollment completion up 28%

Enrollment completion increased by 28%. The core driver was making Expert Guidance the default path and reducing the number of decisions users had to navigate alone.
