Halsey plan and Rowan plans are time based incentive wage plans. I have tried to check for the possible benefits the worker can get if he does work quickly than the standard time (S) . Halsey method seems reasonable but when I have tried to find the numerical profit of Rowan plan, it seems as the worker is always penalized.
As simplified,the benefit that a worker is getting from this incentive plan is always negative. So why and where is Rowal plan used?
