Design thinking is a crucial approach for solving complex problems, particularly in data analysis. Design principles can inform data problems by encouraging a holistic and systematic approach to problem-solving. Designing from first principles involves starting with the foundational level, building up solutions one clear piece at a time, rather than iterating out of the middle of a problem. This approach ensures clarity and alignment with the desired solution. Thinking in systems is essential for anyone working on complex problems, as it forces consideration of interdependencies and the impact of changes. Design systems, not pages, prioritize understanding how components interact with each other. Value reusage involves valuing consistency over change for change's sake, encouraging reuse of patterns, queries, metrics, and data definitions to make the codebase easy to maintain and unambiguous. By applying these principles, organizations can provide a valuable framework for solving complex problems across their company.
