In industrial engineering, the standard time is the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method. It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may occur but have not been observed.

Usage of the standard time
Time times for all operations are known.
Techniques to establish a standard time
The standard time can be determined using the following techniques:
- Time study,
- Predetermined motion time system aka PMTS or PTS,
- Standard data system,
- Work sampling.
Method of calculation
The Standard Time is the product of three factors:
- Observed time: The time measured to complete the task.
- Performance rating factor: The pace the person is working at. 90% is working slower than normal, 110% is working faster than normal, 100% is normal. This factor is calculated by an experienced worker who is trained to observe and determine the rating.
- Personal, fatigue, and delay (PFD) allowance.
The standard time can then be calculated by using:
