What is the Double Diamond?

• The Double Diamond is a visual representation of the design and innovation process. It’s a simple way to describe the steps taken in any design and innovation project, irrespective of methods and tools used (from The Double Diamond).

What are the phases of the Double Diamond?

• Problem
  1. Discover
     1. Start from a challenge you want to solve and diverge to understand the real problems and user needs.
     2. Employ quantitative and qualitative research. Some useful tools and techniques to use include user research, focus groups, observation, customer interviews, data analytics, competitive research, empathy mapping, and more.
  2. Define
     1. Converge to define the one problem you want to focus on.
     2. To clearly define problems, it is possible to employ journey mapping, or conduct a SWOT analysis.
     3. The problem should be real, focused, and as big as possible. A useful tool to select the problem can be the value vs. complexity framework.
• Solution
  1. Develop
     1. Start from the problem definition and diverge to ideate possible solutions.
     2. Use tools such as team Brainstorming, mind mapping, storyboarding, and running design sprints.
     3. Prioritize the solutions based on impact and feasibility.
  2. Deliver
     1. Converge to select a solution to Prototype and test.
     2. Different types of prototypes include, sketches, mockups, clickable prototypes, MVPs, or even using competitive/similar products.
     3. Popular tools and techniques for testing include, A/B testing, customer interviews, user testing, distributing surveys, and product beta testing.
     4. Presenting the solution to stakeholders can be crucial for earning buy-in and alignment.
