What is this thing we call "design"?

Today I attended a lecture by Nigel Cross titled, "Designerly Ways of Knowing: Understanding how Designers Think and Work".

For me, the "take home" stuff came near the end when Nigel juxtaposed his analyses of conventional problem solvers, and great designers. Here are my notes:

Conventional problem solvers:

• tackle the problem in the 'easiest' way
• accept the problem rules
• adopt standard problem representations
• re-use previous solutions

Expert designers:

• tackle the problem in a 'difficult' way
• challenge the problem rules
• construct novel problem representations
• create new solutions from first principles

Where do you fit in?
