Q. Explain Gantt task and bonus plan?

Gantt task and bonus plan: this plan has been devised by the H.L. Gantt and is the only one that pays a bonus percentage multiplied by the value of standard time. Under this system, fixed time rates are guaranteed. Output standards and time standards are established for performance of each job. Workers competing the job within the standard time or in the less time receive wages for the standard time plus a bonus which ranges from 20 per cent to 50 per cent of the time allowed and not time saved. When a worker fails to turn out the required quantity of a product, he simply gets his time rate without any bonus.
