Great design can encourage out-of-the-box thinking and innovation. Great design can help break down complex problems into manageable, effective parts. Great design can improve usability, accessibility, and the overall experience. But one of the toughest design challenges is staying focused and ruthless with design decisions.
Good questions, Raika, especially #6. People have made great careers and even great companies by asking "How can I simplify this?" See Jobs, Steve.
Thank you!
