What do you Mean Time Study? | Steps of Time Study
Time study is a method of measuring work for recording the times of performing a certain specific task or its elements carried out under specified conditions. An operator does same operation (task) throughout the day. Time study help to define how much time is necessary for an operator to carry out the task at a defined rate of performance.
Time study is also called work measurement. It is essential for both planning and control of operations.
According to British Standard Institute time study has been defined as “The application of techniques designed to establish the time for a qualified worker to carry out a specified job at a defined level of performance.”
Steps in Making Time Study:
Stop watch time is the basic technique for determining accurate time standards. They are economical for repetitive type of work. Steps in taking the time study are:
- Select the work to be studied.
- Obtain and record all the information available about the job, the operator and the working conditions likely to affect the time study work.
- Breakdown the operation into elements. An element is a instinct part of a specified activity composed of one or more fundamental motions selected for convenience of observation and timing.
- Measure the time by means of a stop watch taken by the operator to perform each element of the operation. Either continuous method or snap back method of timing could be used.
- At the same time, assess the operators effective speed of work relative to the observer’s concept of ‘normal’ speed. This is called performance rating.
- Adjust the observed time by rating factor to obtain normal time for each element
Normal= (Observed time *Rating)/100
- Add the suitable allowances to compensate for fatigue, personal needs, contingencies. etc. to give standard time for each element.
- Compute allowed time for the entire job by adding elemental standard times considering frequency of occurrence of each element.
- Make a detailed job description describing the method for which the standard time is established.
- Test and review standards wherever necessary.
