Double Diamond Design Skill
Purpose
Guide AI assistants in applying the Double Diamond design process to structure problem-solving, ensure user-centricity, and foster innovation.
The Double Diamond Process
The Double Diamond model consists of four phases, alternating between divergent (opening up) and convergent (narrowing down) thinking.
![]()
Phase 1: Discover (Divergent)
Goal: Understand the problem space, empathize with users, and gather insights. DO NOT assume the problem is known.
Key Activities:
- •Reframing the challenge
- •User research (interviews, surveys, observation)
- •Market research & competitive analysis
- •Stakeholder interviews
- •Trend analysis
Deliverables:
- •Research Report
- •User Personas
- •Empathy Maps
- •As-Is Journey Maps
Phase 2: Define (Convergent)
Goal: Synthesize research to define the core problem to solve.
Key Activities:
- •Clustering insights (Affinity Mapping)
- •Identifying patterns and themes
- •Defining the "How Might We" (HMW) questions
- •Prioritizing pain points
Deliverables:
- •Problem Statement
- •Value Proposition Canvas
- •Revised User Journey
- •Design Brief / Project Scope
Phase 3: Develop (Divergent)
Goal: Generate a wide range of potential solutions.
Key Activities:
- •Ideation workshops (Brainstorming, Crazy 8s)
- •Co-creation sessions
- •Prototyping (Low-fidelity)
- •Service Blueprinting
Deliverables:
- •Wireframes / Sketches
- •Low-fi Prototypes
- •Service Blueprints
- •Concept Testing Results
Phase 4: Deliver (Convergent)
Goal: Select the best solution, test, verify, and refine.
Key Activities:
- •Usability testing
- •Iterative prototyping (High-fidelity)
- •Technical feasibility assessment
- •Implementation planning
Deliverables:
- •High-fi Prototypes / Mockups
- •User Stories / Functional Specs
- •Implementation Roadmap
- •Final Design Assets
Applying the Skill
When to use Double Diamond?
- •Initial project discovery
- •Solving ill-defined or complex problems
- •Innovating new features or products
- •When user needs are unclear
Interaction Guide for AI
1. Discovery Phase Prompts:
- •"Help me plan user research for [Project X]."
- •"What questions should I ask stakeholders to understand the context?"
- •"Create a competitive analysis template."
AI Response Strategy:
- •Suggest research methods suitable for the constraints.
- •Draft interview scripts.
- •Analyze raw research notes to find themes.
2. Define Phase Prompts:
- •"Synthesize these interview notes into key insights."
- •"Help me write a problem statement based on this data."
- •"Generate 'How Might We' questions for [Problem Y]."
AI Response Strategy:
- •Use frameworks like "Point of View" (User... needs... because...).
- •Create persona templates.
- •Cluster loose points into themes.
3. Develop Phase Prompts:
- •"Brainstorm 10 ways to solve [Problem Z]."
- •"Create a low-fidelity wireframe description for [Feature A]."
- •" Facilitate a Crazy 8s session."
AI Response Strategy:
- •Encourage wild ideas (divergence).
- •Suggest mix-and-match techniques.
- •Describe UI concepts in detail.
4. Deliver Phase Prompts:
- •"Create a usability test script."
- •" critique this design based on usability heuristics."
- •"Prioritize these features for MVP."
AI Response Strategy:
- •Focus on feasibility and viability.
- •Suggest metrics for success.
- •Draft acceptance criteria.
Tools & Techniques
| Phase | Techniques | Tools |
|---|---|---|
| Discover | Interviews, Surveys, Desk Research, Observation | Google Forms, Typeform, Dovetail |
| Define | Personas, Empathy Maps, Journey Maps, Root Cause Analysis | Miro, Mural, FigJam |
| Develop | Brainstorming, Mind Mapping, Crazy 8s, SCAMPER | Figma, Balsamiq, Sketch |
| Deliver | Usability Testing, A/B Testing, Prototyping | Maze, UserTesting, InVision |
Common Pitfalls
- •Skipping Discovery: Jumping straight to solutions without understanding the problem.
- •Premature Convergence: Killing ideas too early in the Develop phase.
- •Analysis Paralysis: Getting stuck in research without moving to definition.
- •Ignoring Feasibility: designing solutions that cannot be built.
