Linguistics is a good way of defining the culture of a brand. The vocabulary used by sports and lifestyle brands - running, fitness, training, motorsports - is all about functionality, whereas the vocabulary of the luxury business - handbags, ready-to-wear - is all about the product.

A challenging economy is always good for design. It unites necessity and functionality. You are forced to be creative with poor materials.

Puma was all about function and not at all about design. The founder of the company always believed functionality and performance were the only ingredients that could make Puma successful and design never mattered.

Good design to me is both appearance and functionality together. It's the experience that makes it good design.
