The Double Diamond, also known as the 4D method, is developed as a framework for design processes. It is based on the belief that effective design starts with a thorough exploration and understanding of problems, followed by a focused development and implementation.
The method is often visualized as two diamonds (the double diamond) with moments of expansion and contraction within them, during which results are distilled into usable chunks of information.
Discovery
The first phase, Discovery, is largely about comprehensive research. In this phase, I delve into the organization, its employees, users, competitors, trends, and the state of their respective (online) products and their performance. It’s a mouthful, but essentially, as a UX architect, I want to be well-informed.
I ask questions using methods like the 5 Whys to get to the core of the issues. This process helps create a holistic overview of the on- and offline landscape in which the organization operates, providing a foundation for understanding its dynamics.
Define
In the Define phase, I sift through the data and insights gathered in the first phase, selecting valuable information. I then logically structure and map this information to make it usable. This stage quickly leads to the initial outlines regarding the structure, personas, tone of voice, and storytelling. Methodologies like STDC x Cialdini are employed for this purpose.
It’s akin to creating the blueprints of a building—a detailed plan that serves as a guide for the further development of the project.
Develop
In this phase, the prototyping of potential solutions takes center stage. The structure is outlined as a screen map, clarifying the project scope and making potential iterations clear for all involved parties. It becomes evident which key screens need to be developed as (lo- or hi-fi) wireframes to provide a clear understanding of the user flow and storytelling.
Additionally, a direction is established for the copy text and visuals, ensuring a clear narrative. When necessary, a clickable prototype is created to offer a better experience of the final product to stakeholders and other involved parties, such as designers and developers, or for testing purposes with users. This step enhances the understanding of the envisioned product and facilitates valuable feedback.
Deliver
Last but not least is Deliver, the phase in which the UX end product is presented to the world. In addition to the screen map, wireframes, and prototype, this often includes pixel-perfect page designs that clearly depict how the product will look in reality. Realistic photos, logos, and copy text are added to provide an accurate representation of the product to be built.
This phase is crucial for conveying the final vision and ensuring that the design is aligned with the intended user experience.
