By virtue of this concatenation of processes the modern industrial system at large bears the character of a comprehensive, balanced mechanical process. In order to an efficient working of this industrial process at large, the various constituent sub−processes must work in due coordination throughout the whole. Any degree of maladjustment in the interstitial coordination of this industrial process at large in some degree hinders its working. Similarity, any given detail process or any industrial plant will do its work to full advantage only when due adjustment is had between its work and the work done.
