A friend of mine, on discovery of this site, compared our design philosophy with that of Dieter Rams.
Reading it confirmed a similarity although, of course, his list was generated by true brilliance and then refined by several high profile decades. The comparison was extremely flattering.

..makes a product useful
..makes a product understandable
..is thorough down to the last detail
..is environmentally friendly
..is as little design as possible
