The principles of management apply to all types of organisations, business as well as non-business, small as well as large, public sector as well as private sector, manufacturing as well as services sector. It should be noted here, that the extent of their applicability depends upon the nature of the organisation, business activity, scale of operations, etc.
This principle applies in varying quantities, as the case may be, to a limited company having various departments such as production, distribution, finance, marketing, research and development, etc., in government office where there is a diary/dispatch clerk whose task is to receive and send mails or documents, a data entry operator whose job is to input data on the computer, a peon, an officer and so on. This principle is also applicable to a limited company where there are separate departments, like Production, Finance, Marketing and Research and Development, etc.
