Maintenance

Keeping equipment capable of producing. Planned maintenance is inconvenient; unplanned maintenance is expensive and arrives at the worst moment.

The idea

How it works

Maintenance deferred is not maintenance avoided. It is rescheduled to a moment chosen by the equipment rather than by the organisation, and that moment is reliably during peak demand.

The right regime differs by asset. Preventive scheduling suits equipment that wears predictably, condition monitoring suits equipment that gives warning, and running to failure is legitimate where the consequence is small and the spare is on the shelf.

Working with it

In practice

  1. 01

    Choose a regime per asset

    Preventive, predictive or run-to-failure, based on consequence and on whether failure gives warning.

  2. 02

    Protect the maintenance window

    The window that is always given up to production is not a schedule.

  3. 03

    Record downtime by cause

    Repeated causes are design problems, not maintenance problems.

  4. 04

    Hold spares for the constraint

    A cheap part that stops the bottleneck is expensive to be without.

The components of maintenance

A component is something that exists afterwards which did not exist before — a deliverable or a mechanism, not an intention.

  2. The schedule

    Planned work with protected windows.

  3. The downtime record

    Unplanned stops by cause, so repeats become visible.

Deferred maintenance is rescheduled by the equipment, and it chooses peak demand.
