A manufacturing plant is trying to determine standard production per day for an incentive program. Suppose that the incentive program will pay $1 per unit produced above standard rates

A worker is timed at an average of 280 seconds per unit, with a performance rating of 105%. The plant has an allowance factor of 13%. If the worker later produces 100 units in an 8 hour shift, how much would he receive under the incentive plan?

Standard time = (Average observed time × PF) / (1 - AF) = 280 ? 1.05/ (1 - .13 ) = 337.931 seconds.
Available time = (8 hours)(60 minutes/hr)(60 seconds/minute) = 28,800 seconds available.
Standard production = Available time / Standard time = 28,800 / 337.931 = 85.22 units
The worker produced 100 units, or ~15 more than standard (students may round up the standard production to 86, giving only 14 more units); thus, he would receive $15 (or $14 ) in incentive pay.
