Writing Design Case Studies
Quick Start
Start with the essential framework:
# [Project Name] Case Study
Product: [Name and type] Role: [Your specific contribution] Timeline: [Duration] Platform: [Mobile app/web/etc.]
Brief description of what you designed and why.
[Specific design challenge - what wasn't working and for whom]
[High-level approach and key improvements]
# Workflow
Progress:
- Project Summary - Product name, your role, timeline, platform
- Context - Background, users, market situation
- Problem Statement - Specific design challenge
- Goals & Objectives - What success looks like
- Role & Responsibilities - Your specific contributions
- Research/Discovery - How you understood the problem
- Key Insights - 3-5 findings that shaped design
- Design Strategy - 3-4 guiding principles
- Information Architecture - User flows and organization
- Design Exploration - Iterations and rejected concepts
- Solution Breakdown - Feature-by-feature analysis
- Visual System - UI decisions and components
- Prototype/Interactions - How it behaves
- Validation - Testing and feedback
- Outcome - Results and improvements
- Learnings - Reflection and growth
For each major feature:
### [Feature Name]
**Challenge:** What problem this solved
**Design Decision:** What you created
**Rationale:** Why this approach worked
**Impact:** How it improved the experience
Progress:
- Project Summary
- Context & Problem
- Goals & Role
- Research/Discovery
- Design Strategy
- Solution Breakdown
- Outcome & Learnings
Examples
Example 1: Problem Statement Input: "The app was confusing" Output: "Although the product had useful financial features, the interface lacked visual hierarchy and consistency, making important actions harder to find and reducing user confidence in transaction security."
Example 2: Solution Feature Input: Need to explain dashboard redesign Output:
### Dashboard Overview
**Challenge:** Users couldn't quickly scan their financial status
**Design Decision:** Created a card-based layout with visual hierarchy
**Rationale:** Cards separate information types while maintaining scannable layout
**Impact:** Reduced time to find key information from 45 seconds to 8 seconds
Example 3: Key Insight Input: Research showed users were confused Output: "Users need financial information to be scannable at a glance - they check balances during brief moments throughout their day, not during dedicated review sessions."
Best Practices
- Lead with user problems, not features
- Include specific metrics when available
- Show process, not just polished results
- Use "Challenge/Decision/Rationale/Impact" structure consistently
- Break up text with clear section headers
- Include progress checklists for complex workflows
- Use consistent formatting for repeated elements
- Balance screenshots with explanatory text
- Include research methodology, even if brief
- Show design iterations and what didn't work
- Quantify improvements when possible
- Be specific about your individual contributions
- Start with project context, not your process
- Connect each design decision to user needs
- End with measurable outcomes or clear improvements
- Include honest reflection on challenges and learnings
Common Pitfalls
- Avoiding the template mindset - Don't list every portfolio piece identically
- Skipping the problem definition - Don't jump straight to solutions
- Focusing only on final designs - Show exploration and iteration
- Being vague about your role - Clearly state what you personally did
- Ignoring outcomes - Always include results, even if qualitative
- Over-explaining basic concepts - Assume design literacy in your audience
- Making it about the product - Keep focus on your design process and decisions
