# Redesigning the Checkout Flow
**Company:** E-Commerce Inc.
**Role:** Lead Product Designer
**Timeline:** 6 weeks
**Team:** 2 designers, 3 engineers, 1 PM
**Summary:** Reduced cart abandonment by 35% through a streamlined 3-step checkout process, generating $2M in recovered revenue.
Purpose: Set up why this work mattered
Include:
Example:
## The Problem
E-Commerce Inc. was experiencing 68% cart abandonment—significantly higher than the industry average of 55%. Exit surveys and user research revealed several issues:
- **Too many steps:** Our checkout had 7 screens
- **Forced account creation:** Users had to register before purchasing
- **Hidden costs:** Shipping wasn't shown until step 5
- **Mobile friction:** Forms weren't optimized for mobile
**Goal:** Reduce cart abandonment to below 50% within 3 months.
**Constraints:**
- No changes to existing payment integrations
- Had to maintain PCI compliance
- 6-week timeline before holiday season
Purpose: Show your thinking and methodology
Include:
Example:
## Process
### Research
I started by understanding the problem deeply:
- Analyzed Mixpanel funnel data for drop-off points
- Conducted 10 user interviews with recent abandoners
- Reviewed heatmaps and session recordings
- Benchmarked against 5 competitor checkout flows
**Key Insight:** 73% of drop-offs occurred at the account creation screen. Users wanted to purchase, not commit to a relationship.
### Ideation
I explored several approaches:
1. Guest checkout only (simplest)
2. Social login options (lower friction)
3. Progressive profiling (collect info over time)
4. One-page checkout (Amazon-style)
After weighing feasibility, timeline, and impact, we chose a hybrid approach...
### Decisions Made
- **Guest checkout first:** Made registration optional and post-purchase
- **Transparent pricing:** Showed shipping on the first screen
- **Mobile-first design:** Designed for mobile, then adapted for desktop
- **Progress indicator:** Added clear "Step 1 of 3" indicator
Purpose: Show what you actually created

## Learnings
### What Worked
- **Early user research** prevented us from building the wrong solution
- **Cross-functional alignment** meetings kept everyone on the same page
- **Launching with analytics** let us measure impact immediately
### What I'd Do Differently
- **More A/B testing:** We launched the full redesign at once. Would have preferred to test individual changes to understand what drove results.
- **Earlier mobile focus:** We designed desktop-first then adapted. Starting mobile-first would have been more efficient.
- **Stakeholder education:** Spent too long convincing leadership. Would start stakeholder alignment earlier next time.
### Skills Developed
- Advanced Figma prototyping
- Working with A/B testing frameworks
- Presenting data-driven design decisions to executives
