Which of the following is not a potential benefit of the use of self-directed teams?

How many observations should be made if he wants to be 95.44 percent confident that the maximum error in the observed time is one second? Assume that the standard deviation of the task time is 5 seconds.

Which of the following statements should not characterize an operations strategy toward the design of work systems?

What is the observed time for this task?

A SIMO chart includes:

The normal time for a job is multiplied by the performance rating to obtain the standard time for the job.
