Principles binds people, not appearances.
I separate design thinking from the skills used to express that thinking, which enables me to be comfortable working on cross-disciplinary projects.
Creativity comes from mixing people with different backgrounds, experiences, and culture. You will find solutions in the exchange, in the argument.
My favorite approach is exporting the structure, the principles from one field, onto another one, connecting the dots.
Studying and getting a master degree in business and management besides industrial design gives me a global approach to the industry. Though my approach is user-centered, I never lose sight of the economic reality.
