Which system is designed for the simple payment of per-unit output?

The piece rate wage system is specifically designed to compensate workers based on the number of units they produce or complete. This approach allows for straightforward tracking of productivity, as the worker is paid a predetermined amount for each unit made. It directly ties compensation to performance, incentivizing productivity and efficiency, which can be particularly beneficial in manufacturing or tasks where output quantity can be easily measured.

The other systems mentioned do not operate on the same principle of simple per-unit payment. Time rate wage systems pay based on the amount of time worked, regardless of output; commission-based systems often relate to sales performance rather than direct output; and salary-based systems provide a fixed amount for a period of time, offering no direct link to productivity in terms of units produced. This distinction is crucial in understanding how different compensation methods can impact employee motivation and performance.
