means The coordinated arrangement of many separate parts, people, or systems so they work together toward a single result.

from From 'orchestra,' which the Greeks first used for the semicircular space in front of a stage where the chorus danced and sang — from 'orcheisthai,' to dance. The word later shifted to mean the group of musicians itself, and by the 1800s 'orchestration' had emerged specifically for the craft of assigning music to different instruments so they blend into one coherent whole — a sense that quietly migrated into business and technology to describe making many parts move as one.
