What Is Design Thinking?

Design thinking is a human-centered approach to problem-solving and innovation that emphasizes understanding the needs and desires of the end-user. As an Innovation Methodology, it applies a designer's toolkit and mindset to solve complex problems across various fields, including business, technology, and social challenges. This structured yet iterative framework aims to create solutions that are not only technologically feasible and economically viable but also desirable from a human perspective, often leading to improved customer experience.

History and Origin

The roots of design thinking can be traced back to the mid-20th century, drawing from early studies in design cognition and methods. Figures like John E. Arnold at Stanford University and L. Bruce Archer contributed to the foundational ideas in the 1950s and 1960s, conceptualizing "creative engineering" and systematic design processes.

A significant evolution occurred with the emergence of human-centered design principles in the 1980s. This shift emphasized understanding human behavior and experiences, influencing prominent thinkers such as Donald Norman⁴⁹. In the 1990s, the design consultancy IDEO played a pivotal role in formalizing and popularizing design thinking as a systematic process⁴⁷, ⁴⁸. David Kelley, who founded IDEO in 1991, also established the Hasso Plattner Institute of Design at Stanford University, often referred to as the "d.school," in 2005, which has been central to developing and teaching the methodology⁴⁵, ⁴⁶.

Tim Brown, CEO of IDEO, further brought design thinking to the mainstream business world through his influential articles, notably his 2008 piece in the Harvard Business Review titled "Design Thinking"⁴², ⁴³, ⁴⁴. This marked a turning point, solidifying design thinking as a recognized approach for addressing a wide range of challenges beyond traditional product development⁴¹. The design process associated with design thinking is an iterative process, involving stages of empathy, definition, ideation, prototyping, and testing³⁹, ⁴⁰.

Key Takeaways

• Design thinking is a human-centered approach to innovation, focusing on understanding and addressing genuine user needs.
• It is an iterative and non-linear process, allowing for continuous refinement of ideas and solutions based on feedback.
• The methodology fosters collaboration among diverse teams, bringing varied perspectives to complex problems.
• Prototyping and testing are crucial phases, enabling rapid experimentation and risk reduction before full implementation.
• Design thinking can be applied across numerous sectors, from crafting new products and services to developing business strategies and enhancing organizational processes.

Interpreting the Design Thinking Approach

Interpreting design thinking involves adopting a particular mindset that prioritizes empathy, collaboration, and experimentation. It is not merely a linear sequence of steps but a flexible framework that encourages moving back and forth between phases as new insights emerge. The goal is to move beyond obvious solutions by deeply understanding user challenges, defining problems clearly, brainstorming broadly, and building tangible prototypes for testing and learning³⁸. This approach aims to minimize risk by validating ideas early and iteratively refining them based on real-world feedback.

Hypothetical Example

Consider a hypothetical regional bank looking to improve its customer onboarding process for new checking accounts. The bank observes that many potential customers abandon the application midway, and current customers often struggle with understanding initial account features.

1. Empathize: The design thinking team begins by conducting in-depth interviews and observations with prospective and new customers, as well as bank employees involved in onboarding. Through this market research, they discover that applicants find the online form too long and confusing, while new customers are overwhelmed by the number of documents and digital features they need to set up.
2. Define: The team synthesizes these insights to define the core problem: "New customers need a simplified, intuitive onboarding experience to successfully activate their accounts and understand key features, reducing friction and confusion."
3. Ideate: They then brainstorm a wide range of solutions, from a streamlined online application to interactive tutorials and personalized onboarding calls. No idea is too radical at this stage.
4. Prototype: The team creates low-fidelity prototypes: a simplified paper mock-up of the online application and a short, animated video explaining common initial steps.
5. Test: They test these prototypes with a small group of target customers, gathering immediate feedback. They learn that while the simplified form is well-received, the video needs to be broken into smaller, more digestible segments.
6. Iterate: Based on this feedback, the team refines the prototypes, leading to a new, shorter digital application and a series of concise instructional videos accessible via the bank's mobile app, enhancing the overall customer experience.

Practical Applications

Design thinking is increasingly applied across various sectors, including financial services. It helps organizations navigate complex challenges, particularly those driven by evolving customer expectations and digital transformation³⁶, ³⁷.

In banking, for instance, design thinking has been used to:

• Enhance digital banking solutions: Financial institutions leverage design thinking to create more intuitive mobile applications and online platforms, addressing customer pain points related to transactions, account management, and financial planning³⁴, ³⁵. Companies like DBS Bank and Capital One have implemented design thinking to improve digital interfaces and customer engagement³², ³³.
• Improve internal processes: Beyond customer-facing applications, design thinking can optimize back-office operations, leading to greater efficiency and reduced costs in areas like fraud detection or loan approvals³¹.
• Develop new business models: As fintech startups challenge traditional players, established banks use design thinking to innovate their offerings and remain competitive³⁰. This includes creating personalized financial advice services or new investment tools²⁹.

A major U.S. credit union, for example, used design thinking and Agile methodologies to enhance its members' experiences with banking fees and debit card disputes, leading to improved first-touch resolution and automated processes²⁸.

Limitations and Criticisms

Despite its widespread adoption, design thinking faces certain limitations and criticisms. One common critique is that it can be time-consuming and resource-intensive, particularly in the initial phases of user research and prototyping²⁵, ²⁶, ²⁷. This can pose challenges for projects with tight deadlines or limited budgets.

Another concern is the potential for over-reliance on intuition and a lack of clear metrics for measuring success, making it difficult to quantify the impact of the design thinking process²⁴. Critics also argue that design thinking may sometimes dilute the complexity of actual design work into a rigid, linear process, potentially stifling true creativity and leading to solutions that are "safe" rather than truly groundbreaking²¹, ²², ²³. Furthermore, an excessive focus on the user can sometimes neglect the needs of other stakeholders or broader societal implications²⁰. Some academic perspectives suggest that prevailing theories of design thinking in organizations remain too focused on the "making" paradigm, overlooking deeper social and systemic considerations¹⁹. While it encourages a collaborative organizational culture, companies with siloed departments might find the interdisciplinary nature of design thinking challenging¹⁸. Additionally, design thinking is not a panacea for all problems; it may be less efficient for straightforward technical issues with clear solutions compared to complex, human-centered challenges¹⁷.

Design Thinking vs. Agile Methodology

While both design thinking and Agile methodology are popular frameworks for innovation and problem-solving, they serve different primary purposes and focus on distinct stages of development.

Design thinking is fundamentally about "problem finding" and understanding the context before building. Its emphasis is on empathy, defining the right problem, ideation, and early validation through prototyping and testing. It helps teams identify what problem to solve and why it's worth solving, prioritizing human desirability and exploring new possibilities¹⁴, ¹⁵, ¹⁶. The design process within design thinking is iterative but can be non-linear, allowing for broad exploration and refinement of the problem statement itself.

Agile methodology, on the other hand, is primarily about "problem solving" and efficient execution. It is a project management approach focused on iterative and incremental delivery of solutions to predefined problems¹¹, ¹², ¹³. Agile frameworks, such as Scrum, emphasize rapid development cycles (sprints), continuous feedback loops, and adapting to changing requirements¹⁰. While Agile also incorporates user feedback, its focus is more on the development team and delivering working software or products quickly, assuming the core problem is already understood⁸, ⁹.

In practice, these two methodologies are often complementary. Design thinking can be used in the early stages of a project to ensure the right problem is being addressed and a user-centered solution is conceptualized. Once the problem and initial solution direction are clear, Agile can then be employed to efficiently develop and deliver that solution through incremental iterations⁶, ⁷.
