Design thinking can be broadly applied in fields involving computer products, web services, and user interfaces. It is necessary for such fields to apply design thinking principles to understand users, map processes, get feedback, and iterate on designs. This helps ensure the user interface and processes are easy to understand and attract customers. Many successful web services today used design thinking and prototyping to address real needs, like services for extracurricular activities, transportation, and more. Design thinking helps develop solutions that truly help others.
