Once you have everything ready, you can start your design sprint by following five distinct phases. The 'Understand' phase involves gaining a deeper understanding of the problem, context, and people you are designing for. To do this, you can use tools such as interviews, surveys, observations, empathy maps, personas, or journey maps to gather insights and data. The 'Sketch' phase is about generating ideas for your program idea without judging or filtering them. Brainstorming, mind mapping, storyboarding, or sketching are all useful tools for expressing ideas visually and creatively. The 'Decide' phase is about choosing the best idea or combination of ideas based on criteria and constraints. Dot voting, matrix, or SWOT analysis can be used to evaluate and prioritize ideas. For the 'Prototype' phase, build a realistic and tangible prototype of your program idea that can be tested with users or stakeholders. Mockups, wireframes, role-playing, or video are all useful tools for creating a prototype that simulates key features and benefits of the program idea. Lastly, the 'Test' phase involves getting feedback and validation from users or stakeholders on the prototype. Interviews, surveys, observations, or usability tests are all useful tools for testing the prototype and collecting feedback and suggestions.
