Production function is that part of an organization, which is concerned with the transformation of a range of inputs into the required outputs (products) having the requisite quality level.
Production is defined as “The step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the user.”Thus production is a value addition process. At each stage of processing, there will be value addition.
Edwood Buffa defines production as ‘a process by which goods and services are created’. Some examples of production are: manufacturing custom-made products like, boilers with a specific capacity, constructing flats, some structural fabrication works for selected customers, etc., and manufacturing standardized products like, car, bus, motor cycle, radio, television, etc.
The above figure explains briefly the whole concept of production.
