Problem 1
Magic, Inc. carried out a time study of an existing job to develop new time standards. A worker
was observed for 50 minutes. During that period, 42 units were produced. The analyst rated the
worker as performing at an 85 percent performance rate. Allowances in the firm for rest and
personal time are 10 percent.
a. What is the normal time for the task?
b. What is the standard time for the task?
A traditional job description enumerates the relationship of each job to overall goals.
Question 17 options:
True
False
During a time study in a machine shop, five observations of a milling operation performed by an operator whose rating factor is 95 percent yielded the following times (in minutes): 40, 48, 48, 46, and 42. The allowance for this type of operation is 15 percent. a. Determine the normal time for this operation. b. Determine the standard time for this operation.
