"Design thinking is a human-centered approach to innovation." — Tim Brown, IDEO CEO

Activation Conditions and Trigger Words

• Direct invocation: "Analyze with design thinking...", "empathy map", "divergent ideation"
• Semantic trigger: Facing vague product/service innovation needs that require deep understanding of users
• Combined invocation: "First use design thinking to define the problem, then use Lean Startup to validate"

Method Framework Overview

The core of design thinking is to redefine the problem starting from user empathy; it avoids finding the right answer to the wrong problem through alternating divergence and convergence, rapid prototype iteration, and interdisciplinary collaboration.

Core Principles (3-7, each must be accompanied by ≥2 cross-domain pieces of evidence)

Principle 1: Start from user empathy

One-sentence definition: It is not about asking users what they want, but about observing and feeling what they truly experience.

Cross-domain evidence：

1. Product design: When IDEO redesigned the mouse, engineers tested the feel in a woodworking shop rather than drawing (Source: Kelley, The Art of Innovation, 2001)
2. Healthcare: The Embrace infant warmer team went to rural Nepal to observe and found that scarce electricity was the real bottleneck (Source: Stanford d.school, Embrace Case, 2008)

Application method: Before solving the problem, spend at least 30% of the time observing and interviewing users—see what they do in what situations.

Limitation: Small-sample observation may not represent the entire user group and needs to be supplemented by quantitative validation.

Principle 2: Problem definition is more important than the solution

One-sentence definition: Finding the best answer to the wrong problem is still the wrong answer.

Cross-domain evidence：

1. Corporate transformation: IBM did not sell faster computers but redefined itself as "helping CEOs make better decisions" (Source: Gerstner, Who Says Elephants Can't Dance?, 2002)
2. Financial product: Bank of America Keep the Change did not define itself as a savings tool but as "automatically saving spare change when you swipe your card" (Source: IDEO, Keep the Change Case, 2005)

Application method: Use the HMW format to redefine the problem at least 3 times, and choose the most inspiring angle.

Limitation: Over-redefining may lead to procrastination. A balance is needed between "sufficient definition" and "starting action".

Principle 3: The rhythm of divergence and convergence

One-sentence definition: First generate as many ideas as possible, then critically select and focus.

Cross-domain evidence：

1. Innovation factory: Google X, the moonshot factory, encourages impossible ideas, but when selecting, it strictly filters by physical feasibility (Source: Teller, Google X, 2013)
2. Animation production: Pixar Braintrust lets everyone contribute unreservedly, then the director decides the direction (Source: Catmull, Creativity Inc., 2014)

Application method: During the divergence phase, saying "no" or "but" is prohibited. During the convergence phase, use user data rather than personal preferences to choose.

Limitation: Divergence takes time. Urgent projects must be completed within a limited time.

Principle 4: Rapid prototyping reduces the cost of trial and error

One-sentence definition：The lowest-fidelity prototype gets the most authentic feedback in the fastest time.

Cross-domain evidence：

1. Consumer goods: 3M developed Post-it using homemade adhesive tests (Source: 3M, Post-it Origin Story)
2. VR: Palmer Luckey built the first Oculus prototype with foam board and a phone screen (Source: Luckey, Oculus Kickstarter, 2012)

How to apply：The first prototype must be made within 1 day. Paper, tape, slides, and conversation scripts are all valid materials.

Limitations：Low-fidelity prototypes are not only useless in some fields (such as surgical instruments) but also dangerous.

Principle 5: Interdisciplinary collaboration produces breakthroughs

One-sentence definition：Solutions produced by people from different backgrounds colliding are ones no single discipline could think of.

Cross-domain evidence：

1. Technology: The first-generation iPhone was born from arguments among software engineers, hardware engineers, and designers (Source: Isaacson, Steve Jobs, 2011)
2. Social innovation: In IDEO.org projects, engineers and anthropologists go into the field together (Source: IDEO.org, Field Guide to HCD, 2015)

How to apply：The team must include at least 3 people from different backgrounds. If not, bring in outside perspectives.

Limitations：Interdisciplinary collaboration has high communication costs, and insufficient leadership turns it into everyone talking past each other.

Operating Protocol (Agentic Protocol)

Step 1: Problem classification

Applicable signals：

• Need to understand "what users really want"
• Early innovation stage with vague product definition
• Need to break the mindset of optimizing based on existing solutions

Not applicable signals：

• The problem is already clearly defined and only execution remains (Agile/Lean applies)
• Pure technical optimization (TRIZ applies)
• Urgent operational issues

Step 2: Design-thinking-style analysis

Research dimensions(Each dimension must trace back to a core principle):

1. Empathy map construction：Who is the user? What do they see/hear/think/feel? What do they do?

   • Source principle: Principle 1
   • How to do it: Draw a 5-box map (Think/Feel/Say/Do/See)

2. Problem redefinition：The current "problem" may not be the real problem

   • Source principle: Principle 2
   • How to do it: Rewrite with HMW ≥3 times, choose the most inspiring angle

3. Divergent ideation：Generate 20+ possible solutions to the redefined problem

   • Source principle: Principle 3
   • How to do it: Brainstorm for 10 minutes without judgment, then rank by feasibility and impact

4. Rapid prototype construction：Create the lowest-fidelity prototypes for the Top 3 solutions

   • Source principle: Principle 4
   • How to do it: Paper, whiteboard, conversation—any medium faster than code

5. User testing iteration：Take the prototype to real users for testing

   • Source principle: Principle 5 + Principle 1
   • How to do it: 5 users are enough; observe what they do, not what they say

Step 3: Design-thinking-style output

• Empathy map user persona core insights
• Redefined problem (HMW format)
• Brief description of Top 3 solutions + prototype suggestions
• User Testing Plan

Applicable/Not Applicable Assessment

Problem Type	Applicability	Description
New Product Definition	High	Classic Scenario
User Experience Optimization	High	Empathy and prototyping are inherently suited to UX
Enterprise Service Design	High	Service blueprints are an extension tool of design thinking
Technology-Led Optimization	Medium	Empathy helps but is not the core driver
Daily Operational Decisions	Low	Too slow; use heuristics or data to decide directly

Classic Case Library

Success Cases

1. IDEO Mouse Redesign(Product Design/1990s)

   • Problem: Computer mice were hard to use and uncomfortable
   • Method Application: Went to a woodworking shop to find the right feel and made dozens of foam prototypes for testing
   • Result: The ergonomic mouse was adopted by Apple
   • Source: Kelley, The Art of Innovation (2001)

2. Bank of America Keep the Change(Finance/2005)

   • Problem: How to get low-income people to save
   • Method Application: Observation revealed that people did not lack the desire to save but did not know how much to save
   • Result: Automatically round up card purchases and deposit the difference into savings. 2.5 million new users within one year of launch
   • Source: IDEO Case Study; HBS Case (2007)

3. Embrace Infant Warmer(Healthcare/2008)

   • Problem: Premature infants in developing countries need incubators, but electricity is unreliable
   • Method Application: Conducted field observation in rural Nepal
   • Result: The phase-change material warmer costs only 1% of a traditional incubator
   • Source: Stanford d.school, Embrace Case Study

Failure Cases

1. Juicero Overengineering(Consumer Hardware/2016)
   • Problem: Wanted convenient freshly squeezed juice
   • Misuse: Started from high-end equipment rather than designing from the perspective of user convenience
   • Lesson: Insufficient empathy—a juice pack that can be squeezed by hand does not need a Wi-Fi juicer
   • Source: Bloomberg, Juicero Investigation (2017)

Misuse Detector (≥3 misuse patterns)

Misuse Signal	Detection Logic	Warning Message	Recommended Action
Method and Problem Mismatch	The problem is already clearly defined and only needs execution	"There is already a clear solution; design thinking will slow you down. Using agile iteration directly is faster."	Recommend agile
Skipping Key Steps	Going directly to prototyping skips empathy and problem definition	"Prototyping without empathy and problem definition may be doing the right solution for the wrong problem."	Guide back to empathy
Over-Divergence	Still redefining after 3 HMW redefinitions	"There are already enough perspectives. Choose the most inspiring one and validate it with a prototype."	Force convergence

Honest Boundaries (≥3 specific limitations)

1. Not suitable for urgent problems: The complete process takes days to weeks, and is not suitable for operational issues that need to be handled within a few hours
2. Innovation may only be incremental: Design thinking is good at improving existing concepts and is unlikely to produce zero-to-one breakthroughs (requires first principles/TRIZ)
3. Depends on team composition: If there is a lack of interdisciplinary perspectives, it can easily become a solo show by the designer
4. Observation bias: Empathetic observation of 10 users does not necessarily represent the behavior of 100,000 users, and subsequent quantitative validation is needed
