The Double Diamond model: what is it and should you use it?

The Double Diamond design model, officially invented by the British Design Council in 2005, has become a widely recognized and effective framework for design thinking. This model consists of four stages: Discovery, Definition, Development, and Delivery. Each stage plays a crucial role in the design process, ultimately leading to the creation of successful products and solutions.

The Discovery stage is all about gathering insights and understanding the problem at hand. This is where mind maps, brainstorming sessions, desk research, field research (such as interviews, focus groups, observations), and consumer journey mapping come into play. By immersing themselves in the research process and interacting directly with users, designers can gain a deep understanding of their needs, pain points, and desires.

One company that exemplifies the importance of the Discovery stage is Starbucks. Their design team is required to spend a month working as a barista in one of their venues before embarking on any design projects. This hands-on experience allows designers to see firsthand how their creations will be used by customers. By directly engaging with users, Starbucks ensures that their designs are rooted in real-world insights and are truly user-centric.

Once the Discovery stage is complete, the Definition stage comes into play. This stage involves analyzing and filtering the ideas and data collected during the Discovery phase. It sets the context for product development, assesses the feasibility of the project, and aligns it with the corporate brand. It is crucial to involve different departments in this stage to ensure a comprehensive and well-rounded approach to problem-solving.

Microsoft follows the philosophy of "eating their own dog food" when it comes to design. This means that designers use their own creations in their work, putting themselves in the user's shoes. By doing so, they can better understand the user experience and make necessary design changes quickly and efficiently. This highlights the importance of having professional tools that facilitate seamless design iterations.

Now, let's take a step back and look at the bigger picture. Union Square Ventures (USV), a prominent venture capital firm, has a thesis that aligns with the principles of the Double Diamond model. USV backs trusted brands that broaden access to knowledge, capital, and well-being by leveraging networks, platforms, and protocols. They believe that true alignment and shared values with customers are essential for building trust. This resonates with the idea of involving users and understanding their needs deeply, as emphasized in the Double Diamond model.

So, should you use the Double Diamond model? The answer is a resounding yes. This model provides a structured and effective approach to design thinking that has been proven successful by numerous companies. By incorporating the Discovery, Definition, Development, and Delivery stages into your design process, you can ensure that your products and solutions are rooted in user insights, aligned with your brand, and ultimately meet the needs of your customers.

Here are three actionable pieces of advice to make the most of the Double Diamond model:

1. Embrace the Discovery stage: Invest time and resources in understanding your users deeply. Conduct interviews, focus groups, and observations to gain valuable insights that will inform your design decisions.

2. Collaborate across departments: Involve different teams and stakeholders in the Definition stage to ensure a holistic approach to problem-solving. This will lead to fewer prototypes and fewer issues discovered during testing.

3. Use professional design tools: Equip your designers with tools that allow them to make design changes quickly and efficiently. This will enable them to iterate on their creations and ensure a seamless user experience.

In conclusion, the Double Diamond model is a powerful framework for design thinking that can greatly enhance the success of your design projects. By incorporating the stages of Discovery, Definition, Development, and Delivery, you can create products and solutions that are deeply rooted in user insights, aligned with your brand, and meet the needs of your customers. Embrace the Double Diamond model, collaborate across departments, and use professional design tools to unlock the full potential of your design process.
