Importance Of Time Study

2.1 Time Study

According to Time study in Nieble and Frievald, 2003; is a direct and continuous observation of an activity. This observation is commenced by using timekeeping instrument such as stopwatch which is used in order to record how long the activity commenced. Time study is focusing on the time aspect of work in which leads to understanding of how long it takes to do an operation sequence within activity elements accuracy. This study will then leads to better understanding of how the process is going from pace to pace.

In the Industrial Engineering, time study is often defines as a method to determine how long an activity should be done. This method can be used in several field of industrial engineering such as determining the capacity

2.1.1 Time Study Procedures

In order to commence this method of study, several steps must be done such as selecting the subject of the study, breaking down the whole operation and so forth.

• Selecting Operator

The first step of the whole time study is to determine which subject should be the target of this study. In order to achieve the time study objective in which represents the whole operation, selecting the subject of the study should be fulfill several qualifications. The first, the subject should be completely trained in the method which is used in the operation. The next is the subject must show an interest when commencing the operation. The interest is shown by eager to commence a good operation.

• Recording Information

This study should include several important information regarding to the operation. The information is including facility such as machines, hand tools, layout and so forth.

• Positioning the

Therefore, the division is commenced. By divide into smaller activity, the observation can be done in easier way. In order to commence this division, a consideration of each element should be divided based on their working sequence and should be able to be observed in higher accuracy rate.

2.1.2 Rating Operator Performance

Since the time study is commenced in order to gain full representation of the operation, differentiation in each operator should be concerned. Thus, a rating performance is created for the operator. The rating performance means the rate of how good the operator works, how much effort does the operator gives, how good is the condition and how consistent is operation.

Gaining the rating of the observed subject, an adjustment is created based on this rating which calculated in Performance Rating formula

NT = OT x R/100 (2-1)

Where NT : Normal
