Introduction

Prime members strongly value fast shipping, but many additional benefits remain under-discovered after sign-up. I led the design of a gamification framework that introduced challenges, rewards, and personalized motivation directly into existing Prime journeys.

My role: Lead product designer
Timeline: 3 months, 2024
Collaborated with: Product, Engineering, Data Science, UX Research, Brand, Marketing and Legal
Platforms: Mobile, Desktop

Design Process

I follow an iterative process of:

  • Empathizing with user behavior
  • Defining measurable problems
  • Ideating testable solutions
  • Prototyping for experimentation
  • Testing and learning

Understanding the Problem

Prime engagement drops quickly after sign-up once members establish routine behaviors.

Key questions we aligned on with product and data partners:

  • Which Prime behaviors indicate meaningful engagement beyond shipping?
  • Where do members disengage after onboarding?
  • How can we encourage discovery without adding friction?

This framing ensured we focused on behavioral gaps, not surface-level engagement tactics.

Mapping the Prime Member Journey

I mapped the Prime member journey from sign-up through ongoing usage to identify:

  • Where members first encounter Prime benefits
  • Drop-off points after onboarding
  • High-traffic moments suitable for lightweight motivation

The journey revealed that most members quickly settle into habitual usage with limited reinforcement to explore additional benefits. This insight reinforced the need for contextual nudges embedded into existing journeys, rather than standalone promotional experiences.

Audit

To ground the work, I audited existing Prime customer journeys to understand what was working well and where improvements were needed

Key findings:

  • Prime journeys used inconsistent design themes and components, creating fragmented experiences across surfaces.
  • Several flows were not aligned with the latest Prime brand guidelines and visual system.
  • Some components did not fully meet accessibility standards, including contrast, hierarchy, and interaction states.

This helped identify what worked, what created friction, and what could scale.

Analysis

I reviewed common gamification methods used by leading consumer products and identified patterns that translate well to Prime:

  • Points and rewards that reinforce everyday behaviors, aligning with Prime’s value-driven ecosystem
  • Challenges that guide users toward specific actions through clear goals and time-bound incentives
  • Badges and achievements that make progress visible and create a sense of accomplishment
  • Interactive personalization that adapts challenges and messaging based on user behavior

These insights shaped a Prime strategy focused on embedding familiar gamification mechanics directly into existing member journeys.

Research Insights

Key insights from quantitative data and prior research:

  • Most members are highly familiar with only one or two Prime benefits, while awareness of other benefits remains low
  • Members who are familiar with and use multiple benefits show higher overall engagement with Prime

Helping members discover and adopt additional Prime benefits increases perceived value and strengthens long-term membership retention.

Ideation

To explore how we could increase benefit awareness and drive repeat engagement, I evaluated several directions:

  • Educational prompts to highlight underused benefits
  • Benefit bundling to encourage multi-benefit discovery
  • One-time incentives to trigger initial participation
  • Repeatable incentive loops to encourage ongoing engagement

Each direction was assessed based on engagement potential, scalability, implementation complexity, and fit within existing Prime surfaces. We ultimately focused on repeatable incentive loops as the most effective way to drive ongoing engagement.

Priorities

To shape the experience, I defined the core principles for how the solution should work:

  • Make progress visible to encourage continued participation
  • Reinforce value through meaningful rewards and benefit discovery
  • Keep the experience lightweight and easy to engage with
  • Design for scalability across multiple Prime touchpoints

These principles helped translate the concept into a practical, scalable product experience.

Hypothesis

We hypothesized that introducing a scalable challenge and reward framework within existing Prime touchpoints would encourage members to explore multiple benefits and reduce membership cancellations.

Success Metrics

Primary Metrics

  • Multi-benefit usage
  • Membership retention

Secondary Metrics

  • Participation rate
  • Completion rate

Guardrail Metrics

  • Support tickets
  • Homepage engagement
  • Reward confusion

Opportunities

Three opportunity areas emerged:

  • Create a reusable challenge framework instead of one-off campaigns
  • Remain consistent with Prime Brand standards and internal design system guidelines
  • Use personalization to keep challenges relevant and achievable

These opportunities directly informed the design direction.

Low Fidelity Wireframes

I explored early concepts through low-fidelity wireframes to validate:

  • Entry points and discovery
  • Progress visibility
  • Reward clarity
  • Edge cases such as expiration and partial completion

Early alignment with product, engineering, and legal enabled rapid iteration.

Design System

The experience was built using Prime’s existing design system to ensure scale.

  • Reused standard components (cards, banners, modals)
  • Defined consistent progress and completion states
  • Ensured accessibility, localization, and extensibility

This allowed future challenges to be launched through configuration rather than redesign.

Design Variations

The gamification journey was embedded between two existing sections across most placements. Because of this, a key design goal was to keep the experience as compact as possible so it would not push surrounding content down, while still being visually distinct and scalable across locales and surfaces.
I worked closely with the Brand team to align on three design options that balanced visibility, hierarchy, and density. These options explored different treatments around borders, background color, and emphasis.

High Fidelity Wireframes

Once the structure and rules were validated, I created high-fidelity mocks and interactive prototypes. These screens were used in stakeholder reviews, usability testing, and as the foundation for engineering implementation.

Usability Testing

  • Conducted usability testing with 20 participants across different Prime member segments.
  • Validated ease of use and overall strategy, compared multiple design variations, and asked participants to rate the experience (4.8 / 5 CX score).
  • Feedback highlighted strong clarity and motivation, with participants requesting deeper personalization in future iterations.

Tradeoffs

During the usability testing phase, some users suggested that personalization could increase engagement, since Prime members value different benefits. However, introducing full personalization in the initial release would have significantly increased scope and development time. To balance impact and feasibility, we launched a simpler version first to validate the core concept, then introduced personalization in a later phase once the approach was proven.

Scaling and Collaboration

  • Aligned product, marketing, legal, brand, and email teams on a shared gamification strategy focused on discovery and repeat engagement.
  • Defined multiple high-traffic Prime placements to create a cohesive end-to-end challenge journey rather than a single entry point.
  • Validated with engineering that the framework could scale across surfaces through configuration.

Results

Primary Metrics

  • 10% increase in multi-benefit usage
  • 80% of members who completed challenges maintained their membership

Secondary Metrics

  • +15% participation and completion

Guardrails

  • No meaningful increase in support tickets
  • No negative impact to homepage engagement

Next Phase: AI-Powered Personalization

Following the initial launch, we introduced an adaptive system that gave users the ability to select their preferred Prime benefits such as streaming, shopping, or reading. AI analyzed engagement patterns to recommend the most relevant options, helping users make meaningful choices. The system then surfaced challenges that reinforced their favorite benefits while gradually introducing new ones to expand engagement with Prime.

What I Learned

This project reinforced the importance of treating gamification as a scalable system rather than a one-off feature. Driving meaningful engagement required aligning user motivation, business goals, and data insights while embedding experiences naturally within existing Prime journeys. Collaborating across product, marketing, legal, and engineering showed how decisions around placement, rewards, and feedback loops directly influence adoption and retention.
