What is the difference, if any, between large and small plant as far as process planning requirements are concerned?

Process planning is the basis for the optimization of the whole production scenario and its alternatives, and not only for simple operations.  In the other side, plant layout can affect the total operation of a company, including the production processes, equipment, storage, dispatch, and administration. It has a direct effect upon production efficiency and economics of the operation, the morale of employees and can affect the physical health of operatives.
