"An ideal-seeking system is thus one which has a concept of 'perfection' or the 'ultimate desirable' and pursues it systematically; that is in interrelated steps"

"…a purposeful system which, on attainment of any of its goals or objectives, then seeks another goal and objective, which more closely approximates its ideal" (ACKOFF, 1972)

"The vision ... may not be attainable, but it must be continuously approachable. The vision is not utopian because it is subject to improvement over time. Therefore, it is not a description of an ideal system, but of an ideal-seeking system, the best one can conceive at the time."
