Suppose you have two products x and y. the actual production for a given period was 20 units of X and 250 of Y. What can you infer from this information.
The demand for Y is probably higher than the demand for X.
You can also generate many other mathematical models.
You cant infer anything about X and Y given that you only know the production levels. Now then, if you also knew, say, the prices of X and Y, or the costs of producing x and y, then you could say something.
