Design Thinking

When to Use This Skill

Use this skill when:

• Design Thinking tasks - Working on design thinking methodology for human-centered innovation. covers the 5-phase ideo/stanford d.school approach (empathize, define, ideate, prototype, test) with workshop facilitation and exercise templates
• Planning or design - Need guidance on Design Thinking approaches
• Best practices - Want to follow established patterns and standards

Overview

A human-centered approach to innovation that integrates the needs of people, the possibilities of technology, and the requirements for business success.

What is Design Thinking?

Design Thinking is a problem-solving methodology developed by IDEO and taught at Stanford d.school. It emphasizes understanding users, challenging assumptions, redefining problems, and creating innovative solutions through iterative prototyping and testing.

Core Principles

Principle	Description
Human-Centered	Start with people, not technology or process
Embrace Ambiguity	Comfortable with uncertainty early on
Bias to Action	Learn by doing, not just thinking
Radical Collaboration	Cross-functional, diverse perspectives
Iterate Rapidly	Fail fast, learn fast, improve fast

Phase Characteristics

Phase	Mode	Key Question	Output
Empathize	Diverge	What is the user experiencing?	Insights, observations
Define	Converge	What is the core problem?	POV statement

Point of View (POV) Statement

## POV Statement

**User:** [Specific user type/persona]

**Need:** [Verb - what they need to do]

**Insight:** [Because - surprising insight about why]

---

**Full Statement:**
[User] needs to [need] because [insight].

**Example:**
A busy working parent needs to quickly prepare healthy meals
because they want to model good eating habits for their children
but feel guilty about the time-cost tradeoff.

How Might We (HMW) Questions

Transform POV into actionable opportunity statements:

## How Might We Questions

**POV:** [Your POV statement]

### HMW Brainstorm

Generate HMW questions by asking:

| Lens | Question | HMW |
|------|----------|-----|
| **Amplify the good** | What's working? | HMW do more of [good thing]? |
| **Remove the bad** | What's painful? | HMW eliminate [pain point]? |
| **Explore the opposite** | What if we flipped it? | HMW [opposite approach]? |
| **Question assumptions** | What's assumed? | HMW if [assumption] wasn't true? |
| **Change status quo** | What's expected? | HMW change when/where/who? |
| **Break it into parts** | What are components? | HMW address just [component]? |

### Selected HMW Questions
1. HMW [question 1]?
2. HMW [question 2]?
3. HMW [question 3]?

**Priority HMW:** [The one to ideate on]

Phase 3: Ideate

Generate a wide range of creative solutions.

Ideation Rules

Rule	Description
Defer judgment	No criticism during brainstorming
Go for quantity	More ideas = better ideas
Build on others' ideas	"Yes, and..."
Encourage wild ideas	Think big, no constraints
Be visual	Sketch, don't just talk
One conversation	Listen, build, riff
Stay focused	Keep the HMW visible
