So, if all the activities we mentioned contribute to the final product or service, that means that virtually every department is involved â not just manufacturing or operations, but also human resources, accounting, marketing, and so on. This is the essence of Total Quality Management (TQM).
In economics, the law of increasing costs is a principle that states that once all factors of production (land, labor, capital) are at maximum output and efficiency, producing more will cost more than average. As production increases, the opportunity cost does as well. The best way to look at this is to review an example of an economy that only produces two things - cars and oranges. If all the resources of the economy are put into producing only oranges, there will not be any factors of production available to produce cars.
What is 'Economic Efficiency'. Economic efficiency implies an economic state in which every resource is optimally allocated to serve each individual or entity in the best way while minimizing waste and inefficiency. When an economy is economically efficient, any changes made to assist one entity would harm another.
