5. Results (The impact)
6. Learnings (What you'd do differently)

Time to Read

• **Quick Read:** 3-5 minutes (essential for portfolio)

Section-by-Section Guide

1. Overview Section

**Purpose:** Hook the reader, provide context

**Include:**

• Project name and company
• Your role
• Timeline
• Team size
• One-sentence summary of impact

**Example:**

# 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.

2. Problem Section

**Purpose:** Set up why this work mattered

**Include:**

• Business context
• User pain points
• Key metrics or goals
• Constraints

**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

3. Process Section

**Purpose:** Show your thinking and methodology

**Include:**

• Research conducted
• Stakeholders involved
• Hypotheses formed
• Options considered
• Decisions made (and why)

**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

4. Solution Section

**Purpose:** Show what you actually created

**Include:**

• Visual artifacts (mockups, screenshots, diagrams)
• Key features/changes
• Technical implementation (if relevant)
• How it addressed the problems

**Example:**

## Solution

### The New Checkout Flow

**Before:** 7 screens with mandatory registration
**After:** 3 screens with optional guest checkout
