Defining your problem space does not have to be a daunting task; you can follow some general steps to get started. First, identify your target audience and their context. Who are they, what are they trying to achieve, and what are their challenges? Then, conduct user research to validate and deepen your understanding of their needs and pains. Interviews, surveys, observations, and user testing can provide qualitative and quantitative data. Next, synthesize and analyze your findings to identify patterns, insights, and opportunities. Personas, journey maps, empathy maps, and problem statements can help summarize and communicate your learnings. Finally, refine and prioritize your problem space based on business goals, resources, and constraints. Select the most important and urgent problem to solve for customers and the business.
