The Double Diamond design process is a widely recognized framework for creative problem-solving and design thinking, developed by the British Design Council. It consists of four key phases that split the process into two diamonds: Discover, Define, Develop, and Deliver. Each phase focuses on different aspects of understanding and addressing a problem, helping designers navigate through exploration and solution generation.

Discover |
|||
|---|---|---|---|
| Description | Tools Used | Activities Performed | Outputs |
| In the Discover phase, designers explore the problem space to gather insights. This phase involves extensive research to understand user needs and the overall context. | Surveys, Interviews, Empathy Maps, Contextual Inquiries, Journey Maps | User Interviews, Stakeholder Meetings, Desk Research, Competitive Analysis, Contextual Observation | User Research Report, Key Insights, Opportunity Areas, Personas |
Define |
|||
|---|---|---|---|
| Description | Tools Used | Activities Performed | Outputs |
| The Define phase synthesizes insights from the Discover phase to clearly identify and articulate the problem or design challenge. | Affinity Diagrams, User Personas, Problem Statements, Journey Maps | Synthesizing Research, Identifying Patterns, Defining the Problem, Creating Personas | Problem Statement, Refined Personas, User Journey Maps, Project Roadmap |
Design |
|||
|---|---|---|---|
| Description | Tools Used | Activities Performed | Outputs |
| In the Develop phase, various solutions are created and tested through iterative prototyping and user feedback, exploring ways to solve the defined problem. | Wireframes, Prototypes, Usability Testing Tools, Brainstorming Techniques | Ideation, Sketching, Prototyping, Usability Testing, Feedback Sessions | Low/High-Fidelity Prototypes, Feedback Insights, Refined Ideas, MVPs |
Deliver |
|||
|---|---|---|---|
| Description | Tools Used | Activities Performed | Outputs |
| The Deliver phase focuses on finalizing and launching the solution. The product is tested in real-world conditions, and feedback is used to make any final adjustments. | Launch Plans, User Analytics, Final Testing Platforms | Final Testing, Deployment, Monitoring, Gathering Feedback | Final Product, User Feedback, Performance Reports, Next Steps for Iteration |
