What is productivity? How to measure and calculate it?
In general terms productivity can be defined as the relationship between outputs and inputs.
In which sectors can be applied the definition of productivity?
This definition of productivity is generic and applies in an enterprise, a sector of economic activity or the economy as a whole. Productivity can be used to asses or measure how much output can be extracted from a given input.

What is the mathematical representation of productivity?
Mathematically productivity may be expressed by.
Example of how to calculate productivity
A textile factory works eight hours per day manufacturing 100.000 pants and 50.000 sweaters a month using 110000 and 75000 square meters of polyester cloth, respectively. If the pants section of the factory has 50 workers and the sweaters section 75, we can calculate the productivity as follow:
Measure of materials productivity
According to the formula given before, the materials productivity may be measured as the relation between the quantity of finished products and the materials used in the process.
Therefore, the productivity for the pants and sweaters lines of the factory are:
Measure of labor productivity
The labor productivity may be measured as the relation between the quantity of finished products and the labor hours used in the process.
Therefore, the productivity for the pants and sweaters lines of the factory are:
The productivity of any factor of production or input, can be measured in the form we exemplify before.
