The objectives of the internal control structure for a production cycle are to provide assurance that transactions are properly executed and recorded, and that: a. independent internal verification of activity reports is established.
b. transfers to finished goods are documented by a completed production report and a quality control report.
c. production orders are pre-numbered and signed by a supervisor.
d. custody of work in process and of finished goods is properly maintained.

Aproduction line has three machines a, b, and c, with reliabilities of .96, .86, and .85, respectively. the machines are arranged so that if one breaks down, the others must shut down. engineers are weighing two alternative designs for increasing the line’s reliability. plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. in either case, three machines (a, b, and c) would be used with reliabilities equal to the original three. a. compute overall system reliability under plan 1. (round your intermediate calculations and final answer to 4 decimal places.) reliability b. compute overall system reliability under plan 2. (round your intermediate calculations and final answer to 4 decimal places.) reliability c. which plan will provide the higher reliability? plan2plan1
