Frank's Fabricators has collected the following informa- tion to develop a standard time for producing their high- volume Navigator III, a universal remote control. All of the times are in minutes. Elements Observations 1 2 3 4 5 6 Cycle 1 1.10 3.00 0.92 1.23 1.46 1.80 Cycle 2 1.08 0.88 1.30 1.64 1.78 Cycle 3 1.15 3.20 0.85 1.26 1.55 1.76 Cycle 4 1.16 0.88 1.33 1.52 1.80 Cycle 5 1.07 3.10 0.90 1.28 1.62 1.82 Cycle 6 1.10 0.94 1.30 1.60 1.82 Rating factor 0.95 0.90 1.05 1.0 0.85 1.10 Frequency 1.00 0.50 1.0 1.0 1.0 1.0

(a) Calculate the mean observed time for each element.

(b) Calculate the normal time for each element.

(c) Using an allowance factor of 15% of job time, calculate the standard time for each element.

(d) Calculate the standard time for completing one Naviga- tor III.

(e) If an employee is able to produce at a rate equal to the standard (100% efficiency), how many units should she produce each hour?

(f) If an employee is working at 90% efficiency, how many units should she complete in one hour? (g) If a process improvement has changed the mean ob- served time for element 6 to 1.50 minutes, what is the new standard time for the Navigator III? (h) If the company builds 20,000 Navigator IIIs each month, how much less time does it require using the new process?
