What is the Best Planned Downtime for Your Process?

What is Planned Downtime


In this article, you will learn what is a planned downtime and how it is related to lean manufacturing activities.  Moreover, you shall discover how to define the optimum planned downtime for your operations.

What is a Planned Downtime [minutes]

Planned downtime is a period of time during which operations are restricted in order to implement upgrades, repairs, and other changes.

Unlike in more catastrophic types of downtime, planned downtime occurs when planners have set aside a particular time period to shut down or restrict operations.

This period of time to rest the operations, machinery, and people is important to restore and recharge the conditions of your resources.

The most common planned downtimes are related to:

  • preventive maintenance,
  • planned shutdowns,
  • change-overs,
  • cool-down, etc.

What is the Best Planned Downtime for Your Process?

Determine the best-planned downtime is a complex and sometimes difficult period to estimate.  Since it depends on many factors not associated directly with a particular operation.

For example, you shall consider the downtime of all other operations and equipment associated, but also you must consider its synchronization.

Sometimes, you may need to have a planned downtime in parallel (all downtimes at the same time).

In other cases, you may need to have a planned downtime in series, which means that the order and sequence in which the operations are stopped is relevant and not all machines can be stopped at the same time.

In summary, the best-planned downtimes shall be those that allow you to make the necessary preventive maintenance, changeovers, etc and maximize the overall operations performance.
