Quote by Russell Ackoff
A system is more than the sum of its parts; it is an indivisible whole. It loses its essential properties when it is taken apart. The elements of a system may themselves be systems, and every system may be part of a larger system.
"Science in the Systems Age: beyond IE, OR and MS" 1973
