Features of Production Function
1. Complementary: A producer will have to combine the inputs to produce outputs. Outputs can not get generated without the use of inputs.
2. Specificity: For any given output, the combination of inputs that may be used is clearly defined. What type of factors are needed for the production of a particular product is clearly mentioned before the actual production gets started.
3. Production Period: The period of the production process is clearly explained to the production unit. Each stage of production is given some specific time. Production generally gets completed over a long period of time.
