The two steps in preparing chocolate candy bars are molding and packaging. Personal fatigue and delay allowances are set at 15%. The molding machine operator is rated at 110% and the packer is rated at 80%. Observed cycle times per batch are given below.

Observed Cycle Time in Minutes
Molding 26 30 29 31
Packing 45 50 35 30

Determine the Normal and standard times for both tasks.

#### Solution Preview

We have,
Normal time
= (total time) (% of time working on this task) (rating)/(number of units produced)
Standard time = Total Normal time/(1 - Allowance factor)

For Molding:
Average for the actual Molding cycle ...

#### Solution Summary

The solution illustrates the determination of the Normal and standard times for two tasks. Cycle times per batch are observed.
