Sharpening your pencil is an operation that may be divided into eight small elemental motions. In MTM terms, each element may be assigned a certain number of TMUs: What is the tota l normal time for sharpening one pencil? Convert your answer into minutes and seconds.
At Maggard Micro Manufacturing, Inc., workers press semicon-ductors into predrilled slots on printed circuit boards. The elemen-tal motions for normal time used by the company are as follows:
Reach 6 inches for semiconductors 40 TMUGrasp the semiconductor 10 TMUMove semiconductor to printed circuit board 30 TMUPosition semiconductor 35 TMUPress semiconductor into slots 65 TMUMove board aside 20 TMU
(Each time measurement unit is equal to .0006 min.)Determine the normal time for this operation in minutes andin seconds.
The time study of a work operation at a restaurant yielded an observed time of 4 minutes. The analysis rated the observed worker at 85%. This means the worker performed at 85% of normal when the study was made. The firm uses a 13% allowance factor. The restaurant wants to compute the normal time and the standard time for this operation;

- A call centre that handles customer service telephone calls is monitored by information system that collects data on the number of calls each representative received and the length of time each representative took to answer each call and then to respond to the question or request for service. Managers at the call centre can easily obtain statistics on virtually any part of the process. And data collection is built into the system, making it unintrusive. Obviously, the manager‟s goal is to make sure all calls are answered quickly and that customers are satisfied. Information from the system can then be used in a variety of ways. For instance, a manager can use the information from the system to compare a worker‟s output to that of his colleagues, to his own earlier output, to historical outputs reflecting similar work conditions at other times. He can evaluate the number and duration of calls service representatives answer on a given day. 3.
