F.W. Taylor, founder of the scientific management evolved this system of wage payment. Under this system, there is no guarantee of minimum wages. Standard time and standard work is determined on the basis of time study.

The main characteristics of this system is tat two rates of wage one lower and one higher are fixed. Those who fail in attaining the standard, are paid at a lower rate and those exceeding the standard or just attaining the standard get higher rate. Fort example, the standard is fixed at 40 units per day and the piece rate are 40 P. and 50 P. per unit. If a worker produces 40 units or more in a day, he will get the wages at the rate of 450 P per unit and if he produces 39 units e will get the wages at 40 paise per unit for the total output. Thus, the penalty is very sever and the worker at least tries to produce as much as the standard output.

Under this system, a serve penalty is imposed on the inefficient workers because they get the wages at lower rates. The basic idea underlying in this scheme is to induce the worker at least to attain the standard but at the same time if a worker is relatively less efficient, he will lose much.
