IDEO helped formalize and popularize Design Thinking as a structured approach to problem-solving in the 1990s, and it took until the 2010s for it to reach widespread adoption. Now it’s 2025, and somehow, the most important message of design still hasn’t fully made it through:

The famous Double Diamond was never meant to be a linear process, yet it is often misinterpreted as one. It was never intended as a sequence of steps to be followed. At best, the Double Diamond is a map of a creative process, and just like in hiking, the map is not the territory. The only way to make progress is by moving. Then, every now and then, you revisit the map. Reflect on where you stand. You may find yourself close to your goal because team dynamics played out well and you made a groundbreaking discovery. You might also find yourself back near the beginning because you’ve learned something new about the territory.

This way of thinking is fundamentally at odds with the management needs of organizations. But hey, relax—this isn’t another call for “transformation.” What it does call for, though, is the creation of spaces within organizations that operate on fundamentally different principles. It calls for a fundamentally different culture and a fundamentally different breed of people.

In theory, that’s one of the beauties of organizations—they can, in theory, host all types of people. People who are great at running the existing business, as well as those who are great at inventing the business of tomorrow. The harsh truth is, most organizations fail at the latter. And that’s largely because the most important lessons of design still need to be learned.

What is Non-Linear Thinking?

Most traditional problem-solving follows linear logic: “If we do X, then Y will happen.” While this might work in predictable settings, design lives in ambiguity. Non-linear thinking recognizes that multiple factors interact dynamically, and the best outcomes often come from iteration, experimentation, and sometimes, pure serendipity.

Great design isn’t about rigidly following a plan—it’s about adapting, learning, and uncovering new possibilities along the way. The most iconic designs didn’t start as perfect blueprints; they evolved through feedback, failure, and refinement.

Non-Linear Thinking in Design

Effective designers don’t just execute—they explore. Here’s how non-linear logic drives better design outcomes:

1. Iterative Experimentation – The first idea is rarely the best one. Testing, tweaking, and evolving ideas leads to stronger, more meaningful designs.

2. User-Centric Adaptation – People don’t always behave as expected. The best designs evolve based on real-world interaction, not just initial assumptions.

3. Holistic Systems Thinking – Design doesn’t exist in a vacuum. A great interface, product, or brand must work within a broader ecosystem, ensuring changes don’t create unintended consequences.

Non-Linear Thinking in Business Strategy

Design isn’t just about aesthetics—it’s a critical part of business strategy. Here’s how non-linear logic supports innovation and long-term success:

1. Embracing Uncertainty – Markets shift, trends change, and user needs evolve. Designers who thrive in ambiguity create work that stands the test of time.

2. Serendipitous Discovery – Many of the most groundbreaking designs weren’t planned—they were discovered. Staying open to new insights leads to unexpected breakthroughs.

3. Flexible Execution – The best design strategies are fluid, allowing room for iteration rather than rigidly following a pre-set vision.

4. Rewriting the Rules – Iconic designs don’t just improve what exists; they challenge conventions and reshape industries.

How Designers Can Foster Non-Linear Thinking

To create truly impactful work, teams must break free from rigid, linear processes. Here’s how to make that shift:

• Prototype Early, Iterate Often – Move fast, test concepts, and embrace continuous refinement.

• Encourage Cross-Disciplinary Collaboration – The best ideas often come from unexpected sources. Bring in diverse perspectives to spark new connections.

• Reframe Constraints as Opportunities – Limits force creativity. Instead of resisting constraints, use them to drive innovative solutions.

• Prioritize Feedback Loops – Design is never “done.” Keep learning, iterating, and improving based on user insights.

Conclusion

Design is not a fixed destination. The best designers don’t just execute a vision—they explore, adapt, and refine their work based on new information and unexpected discoveries. By embracing non-linear thinking, designers can create more innovative, impactful, and lasting solutions.

The future belongs to those who think beyond the straight path. Are you ready to embrace the non-linear path forward?
