Integrating Problem Framing and Problem Solving
Simon:
in oil painting every new spot of pigment laid on the canvas creates some kind of pattern that provides a continuing source of new ideas to the painter. The painting process is a process of cyclical interaction between the painter and canvas in which current goals lead to new applications of paint, while the gradually changing pattern suggests new goals.
Rittel:
one cannot understand a problem without having a concept of the solution in mind
one cannot gather information meaningfully unless one has understood the problem but one cannot understand the problem without information about it
concepts derived from these quotes:
back-talk of artifacts/situations
reflection-in-action
incremental development
co-evolution between problem and solution
