11. Jakes Jumbo Jacks has collected the following inform- ation to develop a standard time for building jumbo jacks Observations Cycle 1 Cycle 2 Cycle 3 Cycle 4 Cycle 5 Cycle 6 Cycle 7 Cycle 8 Cycle 9 Cycle 10 Rating factor Frequency Element (in minutes) 3 2.18 1.25 1.70 2.741.57 2.221.23 1.752.661.55 2.201.29 1.722.60 1.57 2.18 1.301.802.561.57 2.21 1.26 1.84 2.581.59 2.22 1.22 1.792.581.61 2.17 1.261.782.601.57 2.211.26 1.752.581.61 2.18 1.301.80 2.601.55 2.17 1.281.782.581.57 1.10 1 2 4 5 0.90 0.80 1.05 0.95 (a) Calculate the mean observed time for each element. (b) Calculate the normal time for each element. (c) Using an allowance factor of 20 percent of job time, calculate the standard time for each element and for the entire job (d) How many units should be completed each hour percent of the if the worker performs at standard? How many units should be completed each hour if the worker performs at 90 percent of the standard? 100 (e)

Explanation / Answer

(a)

(b)

(c)

(d)

Units that should be completed each hour = 60 / 2.2 = 27 units.

(e)

With 90 percent of standard, units completed = 27 x 90% = 24 units
