The general procedure followed in systematic carrying out the time study in production planning is as follows:
- Select the work to be studied.
- Record all the information about the work, operator and surrounding conditions.
- Break down the each operation into small elements.
- Examine each element to ensure that the most effective method and motions are used.
- Measure with a stop watch, the time taken by the operator to perform each element.
- Assess the effective speed of the operator performance, i.e. rating factor.
- Apply rating factor to the observed time to get basic or normal time.
- Determine the allowances to be made.
- Compile standard time.
- The standard time or allowed time is the total time in which a job should be completed at standard performance. It is obtained by adding all allowances to the basic time or normal time.
- The average of times recorded by a work study man for an operation is called representative time.
- The actual time read from a stop watch during time study is known as observed time.
- The assessment of performance of the operator by the time study man is known as rating factor.
