Idle time definition

What is Idle Time?

Idle time is a period of time during which an employee is not engaged in productive activities. It is usually caused by a work stoppage, or simply because an organization is so overstaffed that there is no need for certain employees.

How to Reduce Idle Time

Businesses try to reduce idle time, since employees are still being paid despite not being engaged in any productive activities. There are a number of ways to do this, such as reducing setup times, cross training employees, and using temporary staff who can be released as soon as there is no work left to do.

Advantages of Idle Time

Despite its name, there are several advantages associated with maintaining a certain amount of idle time within a business. They are as follows:

  • Extra capacity. Idle time represents excess capacity. As such, it can be useful when a business is subject to sudden spikes in activity levels, since there is a reserve of labor on the premises that can be directed at dealing with the increased activity.

  • Extra staff time for analysis work. It is easier to analyze a process and strip out non-value-added activities when there is extra staff time available to do so. In essence, you pay to retain staff in the short term, and use these extra personnel to make changes that will eventually result in a more lean and efficient organization.

Idle Time at the Bottleneck Operation

The drive to reduce idle time does not always work if there is a bottleneck operation involved. In this case, the bottleneck must be deliberately overstaffed in order to ensure that it is operating as close to its theoretical capacity as possible, since the throughput generated by the bottleneck usually exceeds the cost of the extra personnel.
