This area of overlapping interest and concern.
I’d somehow never seen this famous diagram by Charles Eames (1969) until yesterday (thanks to Ann Pendleton-Jullian). It’s a beautiful way to talk about the design space.
“1) If this area represents the interest and concern of the design office.
2) and this the area of genuine interest to the client.
3) and this the concerns of society as a whole.
4) then it is in this area of overlapping interest and concern that the designer can work with conviction and enthusiasm.
NOTE: these areas are not static — they grow and develop as each one influences the others.
NOTE: putting more than one client in the model builds the relationship — in a positive and constructive way.”
