Depending on the type and complexity of the problem, different approaches may need to be used to combine data and creativity. For instance, when you have a clear problem and a lot of data, you can use data-driven decision-making to identify and quantify the issue, generate and evaluate alternatives, and select and monitor the best option. Alternatively, if you have a vague problem and a little data, creative problem-solving can be used to frame and understand the issue, generate and explore ideas, and prototype and test solutions. Finally, when you have a complex problem and a lot of uncertainty, design thinking can be employed to empathize with users, define their needs and pain points, ideate and prototype solutions, and test and learn from feedback. For example, if you want to optimize website performance or launch a new product or service, or create social impact or innovation, data from analytics, surveys, market research, customer feedback, interviews, observations, experiments can be used to inform your decisions.
