Prototyping in The Art of Innovation
How IDEO uses rapid prototyping as the 'shorthand of innovation' to transform abstract ideas into tangible solutions through iterative learning cycles
Tom Kelley's foundational 2001 book revealing IDEO's revolutionary design thinking methodology and human-centered approach to innovation
The Art of Innovation: Lessons in Creativity from IDEO, America’s Leading Design Firm was published in 2001 by Tom Kelley, the general manager and co-founder of IDEO. Tom Kelley is the brother of David Kelley, who founded the original David Kelley Design firm in 1978 and later co-founded IDEO in 1991. This book emerged from decades of pioneering work in design thinking and represents one of the first comprehensive guides to IDEO’s revolutionary approach to innovation.
The story of IDEO and this book is deeply intertwined with Stanford University and Apple Computer. David Kelley graduated from Stanford’s Joint Program in Design (now Product Design) in 1977, where he learned a human-centered, team-based approach to design. In 1978, he co-founded Hovey-Kelley Design, which became one of Apple’s earliest design partners.
The relationship with Apple began when Stanford professor Bob McKim introduced David Kelley to Jerry Manock, who was working on Apple projects. This led to Hovey-Kelley Design creating the first commercial computer mouse for Apple in 1980, a project that would define both companies’ futures. Steve Jobs challenged the team to create a mouse that could be manufactured for $10-35, work reliably, and function on everyday surfaces like jeans. The resulting design became a cornerstone of personal computing.
IDEO was formed in 1991 through the merger of four design firms: David Kelley Design (founded 1978), London-based Moggridge Associates (founded 1969), San Francisco’s ID Two (founded 1979), and Matrix Product Design (founded 1983). Bill Moggridge, who had designed the world’s first laptop computer (the GRiD Compass in 1982), chose the name “IDEO” from the dictionary as the combining form of “idea”.
The d.school at Stanford was founded in 2004-2005 by David Kelley and Bernard Roth with a $35 million donation from SAP co-founder Hasso Plattner. This institution formalized and democratized the design thinking principles that had been guiding IDEO’s work since the 1970s.
The book outlines IDEO’s systematic approach to innovation through five fundamental phases:
Human-Centered Design The book emphasizes that innovation must begin with deep empathy for users. IDEO’s approach involves “carefully observing the behavior or ‘anthropology’ of the people who will be using a product or service”. This principle emerged from the recognition that successful products solve real human problems rather than impose technological solutions.
“Hot Groups” and Team Dynamics Kelley introduces the concept of “hot groups” - small, passionate, diverse teams focused on specific goals under tight deadlines. These cross-functional teams bring together different disciplines and perspectives to generate breakthrough solutions. The book emphasizes that “the best way to get a good idea is to get a lot of ideas”.
Rapid Prototyping The philosophy that “prototyping is the shorthand of innovation” runs throughout the book. IDEO’s approach emphasizes creating quick, inexpensive prototypes to test ideas early and often, allowing teams to “fail often to succeed sooner”.
The Deep Dive Methodology The book details IDEO’s intense, quick-turnaround process for tackling complex problems. This approach gained public attention through ABC’s Nightline broadcast in 1999, where IDEO redesigned a shopping cart in five days. The Deep Dive demonstrates how diverse teams can immerse themselves completely in understanding and solving a problem through collaborative brainstorming and rapid prototyping.
The book is organized into 15 chapters:
Chapters 1-2: Foundation
Chapters 3-6: Core Methodology
Chapters 7-11: Implementation
Chapters 12-15: Advanced Concepts
Brainstorming Excellence The book provides specific guidelines for conducting effective brainstorming sessions, including creating playful atmospheres, encouraging wild ideas, and building on others’ contributions. IDEO’s approach emphasizes quantity over initial quality, visual aids, and diverse perspectives.
User Research Techniques Kelley advocates for ethnographic research methods, including field observations, empathy mapping, and user journey analysis. The approach goes beyond asking users what they want to observing what they actually do and understanding their unmet needs.
Cross-Pollination The book emphasizes learning from other industries and disciplines to spark innovative solutions. This approach breaks down silos and encourages teams to look for inspiration in unexpected places.
Organizational Culture The book details how to create “greenhouse” environments that foster creativity, including flexible workspaces, celebration of experimentation, and tolerance for intelligent failure.
The Art of Innovation became a foundational text for design thinking and innovation management. It introduced business audiences to IDEO’s human-centered methodology and helped establish design thinking as a legitimate business discipline. The book’s influence extends beyond product design into service design, organizational development, and strategic innovation.
The principles outlined in the book became the foundation for the Stanford d.school’s curriculum and have been adopted by organizations worldwide. The book’s emphasis on empathy, collaboration, and experimentation has influenced how companies approach innovation challenges across industries.
The shopping cart redesign featured in the book became an iconic case study, demonstrating how design thinking can transform even mundane objects through careful observation, creative collaboration, and rapid iteration. This project showed that innovation isn’t limited to high-tech products but can improve any aspect of human experience.
The Art of Innovation remains relevant today as organizations continue to seek systematic approaches to creativity and innovation. Its practical frameworks and real-world examples provide actionable guidance for teams looking to develop breakthrough solutions to complex problems.
