Design Thinking

Definition: What is Design Thinking?

Design Thinking is an innovation approach that originally stems from the design field and was popularized by the Stanford d.school and IDEO. At its core, it is a structured, iterative process that connects three dimensions: desirability (what do users want?), feasibility (what is technically possible?), and viability (what is business-viable?).

What distinguishes Design Thinking from other innovation methods is its radical user-centricity: instead of making assumptions about customer needs, teams observe real users, develop a deep understanding (empathy), and test solutions early on with prototypes.

Design Thinking is both a mindset (attitude toward innovation) and a method (structured process with concrete tools). In combination with Lean Startup and Agile methods, it forms the methodical foundation of modern innovation.

The 5 Phases of Design Thinking

Phase 1: Empathize

Deep immersion into the world of the user: interviews, observations, customer journey mapping. Goal: to understand real needs, frustrations, and motivations – not what customers say, but what they actually need.

Phase 2: Define

Condense the collected insights into a clear problem statement. The “Point of View” statement (POV) or “How Might We” question focuses the team on the central user problem. Example: “How might we help mid-sized business executives advance innovation projects despite day-to-day operations?”

Phase 3: Ideate

Broad idea generation without evaluation: brainstorming, brainwriting, analogy transfer, SCAMPER. Quantity over quality – aim for 50+ ideas, then cluster and prioritize. Business model patterns can serve as inspiration.

Phase 4: Prototype

Make the best ideas quickly tangible: paper prototypes, storyboards, click dummies, role-playing. Motto: “Build to think, not to ship.” A prototype doesn’t have to be perfect—it has to make a hypothesis testable.

Phase 5: Test

Testing prototypes with real users, gathering feedback, and learning. Based on the findings, the process iterates: back to prototype, ideation, or even problem definition. The process is deliberately non-linear and cyclical.

Core Principles

• User-centricity: The human is at the center – not technology, not the business case.
• Interdisciplinarity: Diverse teams bring together different perspectives and competencies.
• Iteration: Rapid cycles of build-test-learn instead of long planning phases.
• Visualization: Making ideas visible and tangible – post-its, sketches, prototypes instead of PowerPoint.
• Bias toward Action: Doing instead of just talking – testing early instead of endless discussion.
• Failure as a learning opportunity: Failing fast on a small scale prevents expensive failure in the market.

Areas of Application in Companies

• Product Development: Developing new products and services based on real user understanding.
• Business Model Innovation: Design Thinking + Business Model Canvas for new value propositions and revenue models.
• Customer Experience: Improving customer journeys and optimizing digital touchpoints.
• Process Innovation: Rethinking internal workflows from the employee’s perspective.
• Strategy Development: Addressing strategic challenges with creative methods.
• Cultural Change: Design Thinking as a catalyst for a more open, experimental corporate culture.

Design Thinking for SMEs

Design Thinking is not just a method for corporations with innovation labs. SMEs also benefit enormously:

• Leverage customer proximity: SMEs often have more direct customer contact than large corporations – this is the perfect starting point for the empathy phase.
• Apply pragmatically: Design Thinking doesn’t have to take place as a 5-day workshop. Even a focused half-day workshop with 2-3 phases delivers valuable results.
• Prototype quickly: SMEs can move from idea to test faster than bureaucratic corporations.
• Involve the entire team: In small teams, every employee can become an innovator.
• Combine with Lean Startup: Design Thinking for problem understanding + Lean Startup for market validation = ideal SME methodology.

Design Thinking vs. Other Methods

• Design Thinking vs. Lean Startup: Design Thinking focuses on problem understanding and creative solutions. Lean Startup on market validation and business metrics. Ideal: a combination of both approaches.
• Design Thinking vs. Agile/Scrum: Design Thinking discovers the “What” (finding the right solution). Agile/Scrum optimizes the “How” (efficient implementation). Complementary approaches
• Design Thinking vs. Blue Ocean Strategy: Blue Ocean works at the market and strategy level. Design Thinking at the user and solution level. They can be used together.
