PREVENTATIVE OR CORRECTIVE?
Asset management is a major cost for most companies. But could you be spending more than necessary? The type of maintenance model your company adopts can significantly impact your equipment performance and technical resourcing.
Many companies start with a corrective maintenance model, which deals with asset repairs and replacements on an as-and-when-needed basis. However, this might not be the best way to keep your equipment and facilities in good working order, or to optimise their lifespan.
Let’s take a deeper dive into the subject of reactive maintenance programmes and discuss:
• What is corrective maintenance? • What are its disadvantages? • What’s the alternative to corrective maintenance? • What is the difference between preventative and corrective maintenance?
• Which is the best approach for your company?
What is corrective maintenance? All company equipment and facilities need some TLC from time to time. Corrective maintenance is the official term for identifying problems and repairing faults once they’ve occurred. It’s sometimes also referred to as reactive maintenance.
There are two types of corrective maintenance that take place in most companies:
Planned corrective maintenance: this scenario is when a repair or replacement job is scheduled later. Planned corrective maintenance tends to happen when your facilities management team carries out an inspection or work order and spot wear and tear on a non-essential object or component.
Planned corrective maintenance can also be used to manage non-critical equipment; assets where a run- to-failure model won’t affect company operations. Many
Corrective maintenance could be costing your company more than you think, says Elecosoft, as it examines what approach is more suitable for your company.
companies use CMMS software to schedule planned corrective maintenance at a more convenient time once they’ve seen a problem.
Unplanned corrective maintenance: sometimes an asset or component will malfunction when you don’t expect it to, and it needs repairing right away. Unplanned corrective maintenance examples include small things like replacing lightbulbs through to major events like machine component failures.
Unlike breakdown maintenance, where non-operational items need repairing, assets requiring corrective maintenance are still functional or have built-in redundancies. However, leaving the issue unresolved could significantly impact your company operations and productivity or lead to the complete breakdown of equipment.
What are the disadvantages of
corrective maintenance? While the run-to-failure model is a traditional way of managing maintenance, it doesn’t always help your company to work productively. There are several disadvantages to adopting a corrective maintenance strategy, including:
• Unplanned downtime and service interruptions: if an asset suddenly needs repairing, this could impact your overall workflow and cause production downtime.
• Undue pressure on maintenance teams: if you’re not expecting downtime, corrective maintenance work will pressure maintenance and facilities management teams to work quickly. This pressure can raise people’s stress levels and affect their quality of work. Also, technicians are not looking for wider problems when carrying out planned work, which means critical issues get missed.
• Planning and resourcing challenges: if your technicians have their work orders planned for the
